Websites are an extremely popular and efficient form of
information dissemination. The technology for delivering
websites changes rapidly and the public expects a fresh and
interesting layout, newly available video formats, easy navigation,
and current content. The University of Florida/IFAS Center for
Aquatic and Invasive Plants (CAIP) Information Office, under
the direction of Victor Ramey, created the original website
and placed it online in 1995. It included plant information and
images, the Aquatic Plant Information Retrieval System (APIRS)
bibliographic database, the Aquaphyte newsletter, and more.
Over the last dozen years, three portals or gateways have been
added to direct viewers to even more information on aquatic and
wetland plants around the world, and invasive non-native plants
in Florida's natural areas.
Primary CAIP/APIRS Website
In 2005, a major overhaul and update of the primary website
was initiated. After being online for ten years, the underlying
framework and organization of the original website was outdated.
New technology was quickly becoming available to enhance nav-
igation, delivery and appearance. The newly refurbished website
finally went online this summer and definitely deserves a revisit
by those who have not been to this site recently. The overhaul and
update were accomplished by website designer Elizabeth Hatha-
A major enhancement has been the addition of 102 aquatic plant
identification video segments to each respective Plant Information
page. These segments were completed as a video series in the
late 1990s. They were subsequently converted to digital formats,
enabling them to be viewed on the CAIP website as individual
2-3 minute identification video segments. Look for the
video icon in the Plant Information and Images section of
A new series of identification videos on Florida upland inva-
sive plant species was initiated in 2007-2008. Six segments were
produced and have been uploaded to the Plant Information and
Images pages for viewing.
The aquatic plant photographic image collection is being
refreshed using technology that was not available when the
initial website was developed. The CAIP receives requests
for 450 700 images annually, including our botanically accurate
line drawings. Sample uses include brochures, agency reports,
textbooks, educational websites, gardening and other magazines,
PowerPointTM and other multi-media presentations, student
papers, poster presentations, and more. A good example is the
recent publication in Hydrobiologia (2008) 595:9-26, Global
diversity of aquatic macrophytes in freshwater by P.A. Chambers,
P. Lacoul, K.J. Murphy, and S.M. Thomaz, in which line draw-
ings produced by the CAIP were used. Image requests continue
to come from all over the world, including Canada, Belgium,
France, Poland, and Nigeria, to name just a few.
Plant Management in Florida Waters
This portal was created in cooperation with the Florida Depart-
ment of Environmental Protection's Bureau of Invasive Plant
Management (now under the direction of the Florida Fish and
Wildlife Conservation Commission (see article, p. 4)). Topics
within this encyclopedia-style portal have been researched in the
APIRS and other libraries,
written for the non-scien-
tific public, and reviewed by
content experts. More than
400 major and minor topics
are addressed and indexed.
Aside from the tremendous
reception from the general
public, the Plant Management in Florida Waters portal also is prov-
ing to be especially helpful to professionals in the field. Aquatic
herbicide applicators are encouraged to carry a supply of "web
cards" for citizens who have questions about plant management
activities. This web card refers interested people to the website,
which is a reliable source of accurate information about aquatic
plant management. Thus, a useful tool is put into the hands of
pesticide applicators for their interactions with the public, and a
trusted University of Florida website is made readily available
to those with questions and concerns about aquatic plant man-
agement. Web cards also are distributed at various environmental
education events throughout the year to publicize this Internet
resource and to make the public aware of invasive plants as an
important environmental topic.

Portals to Education
Since 2005, the CAIP Information Office and the Bureau have
collaborated on the Florida Invasive Plant Education Initia-
tive and Curricula portal at http://plants.ifas.ufl.edu/education,
and the Florida Invasive Plant Education Initiative In the
Parks portal at http://plants.ifas.ufl.edu/parks/ under the direction
of Amy Richard. The primary goal of both programs is to raise
public awareness of invasive plant problems in Florida.
The first portal is for particular use by science teachers and sup-
ports extensive programs developed to provide in-service training
to Florida science teachers. Training topics include plant identi-
fication of native, non-native and invasive plants; the ecological
and economic impacts of non-native invasive plants in Florida;
the numerous management issues regarding invasive plants; and
invasive plant prevention strategies.
The latter portal is for particular use by Florida State Park
rangers, biologists, environmental volunteers and other staff. It
provides management and identification information for native,
non-native and invasive plants, including comprehensive invasive
plant management plans for 42 species; a glossary of plant terms;
and an invasive plant brochure template that can be customized
for individual parks; 90 individual PDF files on invasive and non-
native plant species (from the Invasive and Non-native Plants You
Should Know -F ..... ,,iii,. ,,i Cards publication); and a Find Plants
in Your Region section with links to native and non-native plant
information for all of the five Florida State Park Districts.
Additional Website Projects
The IFAS Assessment of Non-Native Plants in Florida '
Natural Areas website was developed by the UF/IFAS Invasive
Plants Working Group so that University of Florida-IFAS
Extension faculty from all departments could provide consistent
recommendations concerning the use of non-native plants. The
IFAS Assessment is available on the CAIP primary website
(http://plants.ifas.ufl.edu/assessment/), and new results are posted
The Osceola County Hydrilla and Hygrophila Demonstration
Project website (http://plants.ifas.ufl.edu/osceola/) describes a US
Environmental Protection Agency (EPA) funded project examin-
ing the biology of Hydrilla verticillata and Hygrophila polysper-
ma, invasive species management strategies, and new research
and technologies under development. The site is used to com-
municate with residents of Osceola County and other interested
groups about aquatic plant management activities that are occur-
ring throughout the county. This is a cooperative project with the
UF-IFAS Osceola County Extension Office, Osceola County, and
n order for researchers and natural area managers to conduct
research and apply invasive plant management techniques
in the most efficient and informed manner, it is essential that
they be apprised of the total body of scientific literature sur-
rounding each species of concern. This literature is widely
scattered in international, national, and regional journals, in
proceedings from professional symposia, in books, and in
agency reports. Much of this literature, especially the "gray
literature" (proceedings, state and federal agency reports,
etc.) often is not available using common Internet searches
(although this is rapidly changing), and it is not collected
under one database "umbrella." This complicates literature
searching by individuals and necessitates multiple, individual
site visits, author contacts, and/or academic library access to
multiple databases for locating published research.
Since the early 1980s, the Aquatic Plant Information
Retrieval System (APIRS) has been developed as a source
of bibliographic information for both aquatic and upland in-
vasive plant researchers, managers, graduate students and oth-
ers around the world. This information includes the scientific
literature (research articles, books, and reports) about aquatic
and wetland plants worldwide, and upland invasive plant spe-
cies listed by the Florida Exotic Pest Plant Council (FLEPPC).
APIRS staff continues to identify and catalog the scientific
literature in these areas. Annotated citations (not full-text) are
uploaded to the APIRS online database and made freely avail-
able to environmental managers, scientists, graduate students
and others via the website:
During the past year, approximately 2,600 new records were
added to the APIRS database, and there are more than 71,000
annotated citations in the APIRS Online database in total.
Citations include plant lists and keywords provided by reader/
cataloger Mary Langeland.
According to Google AnalyticsTM, the APIRS database
has received almost 20,000 queries in the past year. Visitors
range from 121 different countries/territories, with the major-
ity (65%) from the U.S. By continent, visits to APIRS were as
follows: Americas, 5,272; Europe, 1,032; Asia, 651; Oceania,
173; Africa, 99; Others, 7.
APIRS welcomes contributions of publications for the
citation database, either as reprints or as PDF files. Only an-
notated citations are entered into the database.

Florida's Invasive Plant Education Initiative
by Amy Richard, Coordinator
In 2005, the Florida Invasive Plant Education Initiative was launched as a collabora-
tive effort between the CAIP Information Office and the Florida DEP's Bureau of
Invasive Plant Management (see Aquaphyte Volume 25, Number 2 Winter 2005). Staff
at the CAIP Information Office began to work with teachers to find ways to meld the
wealth of preexisting CAIP educational materials and resources into science lessons
and activities that could be used in classrooms around the state in a concerted way. This
initiative, which focuses largely on aquatic plants, also includes upland invasive plants,
and is among the first of its kind in the United States.
For the past three years, we not only have been assembling and distributing resources
for teachers to use in the classroom, but have also developed content and delivery strat- .
egies for a number of core lessons or teaching modules. The modules are designed to
cover science topics and activities that teachers are required to teach to meet state stan-
dards and benchmarks, and are delivered on the web via QuickTime and FLASH in an Teachers examine the leaves of water
effort to make the presentations available 24 hours a day, seven days a week, in keep- hyacinth plants at the CAIP 2008
ing with current nc" media" trends and technology. During the development process,
groups of teachers throughout Florida were asked to review and provide feedback on the content and presentation of these core lessons
and activities. This inclusive approach was appreciated and contributes to the enthusiasm many educators have for the materials.
The intention of these lessons is to provide the tools for students to become responsible environmental stewards as adults. In addition,
they deliver a message that hopefully will help ease some of the conflicts and negative attitudes often directed at the plant manage-
ment arena by citizens unaware of the problems and expense created by invasive plants in Florida and elsewhere.
The Education Initiative is the first program to provide such intensive in-service training for Florida science teachers (i.e., upper
elementary, middle and high school levels) on the subject of aquatic and upland invasive plants. These annual "PLANT CAMPs," held
for 4.5 days in mid-June, include field trips and rigorous hands-on plant identification activities as a way of generating excitement and
interest in the curriculum. Teachers also earn as many as forty hours of professional development continuing education units (CEUs).
Ultimately, the camps provide teachers with greater background knowledge on Florida's native, non-native and invasive plants before
they begin to teach the topic to their students. So far, the Initiative has trained 94 teachers. At least 250 teachers have been introduced to the
materials/lessons on a more limited
basis as a result of outreach mini-
workshops and events.
For the past two years, we have
added information and training
about invasive animal species to
our PLANT CAMPs by collabo-
rating with the Florida Fish and
Wildlife Conservation Commis-
sion (FWC) Project WILD program,
a wildlife-focused conservation
and environmental education pro-
gram for educators and their stu-
dents (kindergarten through high
school). This year, PLANT CAMP
participants graduated from the 4-
day workshop with both Invasive
Plant and Project WILD certifica-
tion. It is hoped that as a result of
this collaboration, Florida's future
taxpayers will have a better under-
standing of the challenges we all
face from invasive species both

Florida's Invasive Plant Management Program
Under New Leadership
By Bill Caton, Section Leader, Invasive Plant Management
Division of Habitat and Species Conservation, Florida Fish and Wildlife Conservation Commission
During the 2008 Session of the Florida Legislature, Senate
Bill 1294 was passed and became law on July 1, 2008. This
law transferred the authority to direct and operate the State's
invasive plant management program from the Department of
Environmental Protection (DEP) to the Fish and Wildlife Con-
servation Commission (FWC) and the Department of Agri-
culture and Consumer Services (DACS). The FWC is now the
lead agency for:
Aquatic Plant Management in Public Water Bodies
directing the control, eradication, and regulation of nox-
ious aquatic weeds;
guiding and coordinating the activities of all public
bodies, authorities, agencies, and special districts charged
with the management of aquatic plants;
disbursing funds to districts, special districts, or other
local authorities for the purpose of operating a program for
managing aquatic plants in the waters of state responsibility;
directing the research and planning related to these activi-
Upland Invasive Exotic Plant Management on Public
achieving eradication or maintenance control of upland in-
vasive exotic plants on public lands;
assisting state and local government agencies in the
development and implementation of coordinated management
plans for the eradication or maintenance control of upland
invasive exotic plant species on public lands;
contracting, or entering into agreements, with entities in
the State University System or other governmental or private
sector entities for research concerning control agents; and the
production and growth of biological control agents.
Any person or public agency wanting to control, eradicate,
remove, or otherwise alter any aquatic weeds or plants in wa-
ters of the state must obtain a permit for such activity from the
FWC unless the activity or waters are expressly exempted by
FWC rule. DEP's rule chapters 62C-20 and 62C-54, Florida
Administrative Code (F.A.C.) have been transferred to the
FWC under rule chapters 68F-20 and 68F-54, F.A.C., respec-
tively. The only changes to these rules were technical in nature
primarily to change all references of DEP to FWC.
All personnel and equipment of the DEP Bureau of Invasive
Plant Management have been transferred to the FWC Invasive
Plant Management Section (FWC's equivalent of a Bureau).
The FWC Executive Director, Ken Haddad, has clearly stated
that initially there will be no change in how the program
operates. There are a lot of administrative issues involved with
moving a program from one agency to another. After these is-
sues are worked out and the transition is complete, the agency
will look for ways to integrate operations with other internal
programs to create improvements and enhance efficiency.
In addition, the portion of the DEP Bureau of Invasive Plant
Management responsibility related to the importation, trans-
portation, cultivation and collection of aquatic plants for busi-
ness purposes and the possession of prohibited aquatic plants
was transferred to the DACS by Senate Bill 1294. The DACS
now maintains the list that regulates the possession of prohib-
ited aquatic plants. As a result of this change, DACS now has
authority over the State's noxious weed list and the prohibited
aquatic plant list. Any person wanting to import, transport, cul-
tivate or collect plants for business purposes or possess prohib-
ited plants must obtain a permit from the DACS, Division of
Additional legislation will be needed in the 2009 session of
the Florida Legislature to address unresolved issues regarding
the Invasive Plant Control Trust Fund (base funding for aquatic
plant control activities that was established by the Legislature
in 1971; currently funding comes from fuel taxes, boat regis-
tration fees, and documentary stamps), authority for allowing
activities on sovereign submerged lands, and regulatory en-
forcement. FWC is committed to working with the Legislature
and stakeholders to get these issues resolved and to ensure that
Florida's Invasive Plant Management program continues to be
the best of its kind in the nation.
The original Bureau of Aquatic Plant Research and Control
was established in 1969 and funded in 1970 under the Florida
Department of Natural Resources (DNR). Dr. Alva Burkhal-
ter was appointed Bureau Chief beginning in 1971. The DNR
later became the Department of Environmental Protection and
the Bureau underwent internal name changes to the Bureau of
Aquatic Plant Management, and later, when the Florida Leg-
islature directed the Bureau to begin an upland invasive ex-
otic plant management program, the Bureau of Invasive Plant
Management. It is now the Inva-
sive Plant Management Section

At the Center in 2008
by William T. Haller, Acting Director
The Center for Aquatic and Invasive Plants (CAIP) has been very much involved with invasive plant management for the past
thirty years. The CAIP is under the auspices of the Institute of Food and Agricultural Sciences (IFAS) at the University of Florida
and is responsible for coordinating, facilitating and assisting faculty in
pursuing research, extension and teaching issues in invasive plant biol-
ogy, ecology and control. UNIVERSITY 9f

The CAIP grew under the leadership of former Center directors Arnette Mace, Joe Joyce and Randall Stocker, and its respon-
sibilities expanded into research, education and control of upland invasives in natural areas. The number of faculty, staff and
students increased and many federal (Department of Agriculture, Army Corps of Engineers, Department of Interior, Environmental
Protection Agency) and state agencies (Department of Environmental Protection, Fish and Wildlife Conservation Commission
(FWCC), Department of Agriculture and Consumer Services (FDACS), water management districts, county and private agencies
and foundations continue to support research and education programs at the CAIP
Drs. Alison Fox, Randall Stocker, Vernon Vandiver, David Sutton and Curtis Rainbolt have all retired within the last several
years, and budget problems have not allowed for their replacement. Nevertheless, the IFAS Assessment of Non-native Plants in
Florida Natural Areas (http://plants.ifas.ufl.edu/assessment/), extension training programs such as the UF/IFAS CAIP Aquatic
Weed Control Short Course, and the many research efforts conducted by these former staff members continues.
Newer faces around the Center include Jeremy Slade, a new biologist focusing on monitoring of large-scale hydrilla control
projects for the Florida FWCC, and post-doctoral associate Lyn Gettys working on ecotypic differentiation of Vallisneria americana.
Dr. Chris Mudge completed his PhD degree in December 2007 and is now at Vicksburg, Mississippi with the US Army Corps
of Engineers, Waterways Experiment Station. Dr. Tomas Chiconela completed his PhD degree in May 2008 and has assumed
teaching responsibilities in plant protection at Eduardo Mondlane University in Maputo, Mozambique. Dr. Mercedes Roquela
recently completed a one year sabbatical working on ALS enzymes, herbicide metabolism, and resistance with Dr. Greg
MacDonald and Dr. Atul Puri. Dr. Roquela has returned to her weed scientist position at Universidad Pfiblica de Navarra,
Pamplona, Spain. Exciting research projects on Lygodium control, evaluating new herbicides for aquatic use, searching for insect
biocontrols for hydrilla in East Africa, and many other projects keep the scientific staff across Florida at the cutting edge of devel-
oping new and improved technologies for invasive plant management.
The annual Aquatic Weed Control Short Course held in South Florida at Coral Springs attracted 450 attendees once again in
May 2008. Plans are currently underway for the 2009 Short Course to be held at the same location May 4-7, 2009 (http://confer-
ence.ifas.ufl.edu/aw/) In addition, the second Northwest Florida Right-of-Way and Aquatic Pesticide Applicator Training
Course will be held in Panama City in late September 2009 (http://conference.ifas.ufl.edu/applicator/index.htm).
The CAIP Information Office has redesigned its award winning website (see cover article), and the educational efforts with
Florida Fish and Wildlife Conservation staff and CAIP continue at an accelerated pace with the Education Initiative (see pg. 3).
As we move into this initial year of collaboration with the Invasive Plant Management Section of the Florida Fish and Wildlife
Conservation Commission (formerly the Department of Environmental Protection's Bureau of Invasive Plant Management, we
look back and reflect on the breadth of information and materials that have been developed over the past 25+ years with their
support. This productive partnership has built a strong foundation of information services thanks to individuals like (the late) Vic
Ramey at the CAIP, and Jeff Schardt and Don Schmitz of the new FFWC Invasive Plant Management Section, who recognized
the importance of educating Florida's citizens about invasive species. Together, they produced a wide variety of materials that
continue to be used on a regular basis by agency personnel, biologists, field technicians, researchers, students and teachers for
the purpose of identifying, managing, and learning more about Florida's non-native and invasive plants. Veteran Aquaphyte read-
ers will recognize the numerous items which have been introduced in this newsletter over the years and are also viewable on the
newly renovated CAIP website: http://plants.ifas.ufl.edu/node/596 Please take a moment to visit.

THE RIVERSCAPE AND THE RIVER.
By S. M. Haslam. 2008. ISBN 9780521839785. Cambridge University Press. htt: //www.cambridge.or/
Dr. Haslam examines how the quantity, function and ecology of water changes as it moves from watershed to river. The develop-
ment of river and riverscape, their ecology, the effect of human activities (such as water abstractions, flood control and management
for recreational use) and water resources are described both in principle and using case histories. Contrasting examples are given
from across the world, including Iceland, Hungary, Malta, Britain and the USA, which enables an understanding of how water and
riverscape interact with each other, and with human impact.

key presentations from a series of biennial International Conferences on the Ecology and Management of Alien Plant Invasions
(EMAPi) beginning in 1992 (see de Waal et al. 1994, Pysek et al. 1995, Brock et al. 1997, Starfinger et al. 1998, Brundu et al. 2001,
Child et al. 2003). This volume aims to contribute to this growing field, exploring human perceptions of plant invasions and the role
of humans in the invasion process from different perspectives and geographical areas. It also covers case studies of the biology and
ecology of invasive species, mechanisms of invasion and ecological impacts, while offering solutions through a variety of control
and management techniques.

chaux) using a miniaturised monitoring test system consisting of
a microbioreactor of reduced volume and integrated sensors for
the online measurement of physiologic parameters, like oxygen
production and different parameters of fluorescence. Different
concentrations of both chemicals were applied to leaves of E. ca-
nadensis and the physiologic endpoints evaluated after 1 h... The
mini-PAM technique implemented in the presented system al-
lowed for a clear monitoring of the kinetic of BAC and atrazine,
showing their distinct mode of action..."
There are indications "that the microbioreactor test system might
be suitable, on the one hand, for the laboratory screening of poten-
tial short-term toxicity of contaminants on aquatic plants, and on
the other hand, serve as an in situ field biomonitoring system for
the rapid detection of pollutants in water."
Hydrothermal processing of biomass from invasive aquatic
plants. By Catallo, W.J., Shupe, T.F., Eberhardt, T.L. 2008.
Biomass Bioenergy 32(2):140-145.
"The purpose of this study was to examine the hydrothermal
(HT) treatment of three invasive aquatic plants (i.e., Lemna sp.,
Hydrilla sp., and Eichhornia sp.) with respect to the generation of
semi-volatile hydrocarbon product mixtures and biomass volume
reduction. Identical HT treatments yielded similar semi-volatile
product mixtures for Hydrilla sp. and Eichhornia sp. versus a sig-
nificantly different mixture for Lemna sp...
Currently, there are no data in the public domain on products re-
sulting from HT treatment of vascular aquatic plants, particularly
those which pose ecological problems (i.e., invasive or noxious
nature)... Therefore, the objective of this research was to evaluate
the HT treatment of three major pest aquatic plants with respect
to hydrocarbon yields, chemical composition of semi-volatile mix-
tures, and volume reduction."
Botany new home for tiny aquatics. By Friis, E.M., Crane, P.
2007. Nature 446(7133):269-270.
"Many new constellations in the angiosperm evolutionary tree
have come to light as relationships within the flowering plants
have been explored using molecular analyses. Some of these
changes were not unexpected. But others have resulted in fun-
damental reinterpretations of angiosperm evolution. It will take
some time to digest all the implications of suddenly introducing a
new plant family into discussions of early angiosperm evolution...
Hydatella and Trithuria have not been on the radar screen of most
specialists working on the subject, and there are many pieces of
this puzzle still to work out. Certainly, repositioning the Hydatel-
laceae as the closest living relatives to the Nymphaeales will dra-
matically influence ideas about the early evolution of water-lilies
and their allies, and it will modify important details of character
evolution at the base of the angiosperm tree. Hydatella and Tri-
thuria will inevitably be the subject of detailed investigation in
the coming years. But whatever the outcomes of these studies, the
radical realignment discovered by Saarela et al. should remind us
not to become too comfortable with the current picture of early an-
giosperm relationships, and especially with the details of character
evolution that they imply."
Programmed cell death and tissue remodelling in plants. By
Gunawardena, A.H.LA.N. 2008. J. Experim. Bot. 59(3):445-451.
"PCD is a genetically encoded active process, whereby cells or-
ganize their own destruction. The main objective of this paper is
to review a few select examples of PCD-enabled remodelling in
plants at the cellular, tissue, and organ levels, with an emphasis on
research involving the lace plant-a model system for the study of
developmentally induced PCD."
"The formation of complex leaf shape through the use of PCD is
a rare event across vascular plants and occurs only in a few species
of Monstera and related genera, and in the lace plant (Aponoge-
ton madagascariensis). During early development, the lace plant
leaf forms a pattern of equidistantly positioned perforations across
the surface of the leaf, giving it a lattice-like appearance. Due to
the accessibility and predictability of this process, the lace plant
provides highly suitable material for the study of developmentally
regulated PCD in plants."
The kingdom of the shore: achievement of good ecological
potential in reservoirs. By Moss, B. 2008. Freshwater Reviews
Moss says, in the conclusion of this article, "In the past few hun-
dred years we have assumed that we can alter our environment at
will, without consequence." Reservoirs are an example of this al-
teration. They "...are disabled lakes, usually lacking the diversity
and function provided by a littoral zone." In the "kingdom of the
shore" (a title from William Shakespeare's Sonnet LXIV), where
the land and water interface, Moss suggests that "...the least dam-
aging solutions are mechanisms that promote parsimony of use
rather than response always to continued demand."
Ethnobotany of folk medicinal aquatic plants in Jordan.
By Al-Qura'n, S. 2007. Bot. Review 73(1):51-65.
Most of the area of Jordan is desert with few water resources.
It is considered to be one of the world's ten most poorly watered
countries. It is in or around the "... Jordan and Yarmouk rivers,
marshes, swamps, ditches, geothermal springs... in addition to
small ponds and water resources where the aquatic species with
therapeutic effects are found."
"This study aimed to verify the phytomedicinal wealth present
in the investigated area and to determine the levels of popularity
of different plants, since the investigated area has a uniquely high
level of species diversity." The authors expressed the hope that the
Bedouin and rural peoples would feel an increased "sense of re-
sponsibility for protecting these species from factors that threaten
and endanger them. Consequently, this cultural heritage may be
reinforced because it is aligned with scientific measures."

N. Flor-Arnau. 2008. 132 pp. Real Jardin Bothnico de Madrid.
This 2008 Monograph of the Flora Ib6rica series on the mainland
algae is devoted to the characterization, identification and distribu-
tion of the Iberian charophytes, including Spain, Portugal and the
Baleares Isles. The slender book (only 132 pages) by Santos Ciru-
jano, et. al was published in Spanish by the Real Jardin Botnico de
Madrid. The usefulness of the book lies in the orderly arrangement
and careful, detailed infor-
mation and keys, based on
sampling field trips, reviews
of herbarium specimens and
Cirujano states that the
purpose of the work is to fa-
cilitate the identification of
the charophytes of the Iberi-
an Peninsula. This has been o
accomplished in the book
with detailed, crisply drawn
illustrations, the clear pho-
tographs of specimens, and
the simple, but useful keys
for identification. The book Dr. Eduardo Reyes Pr6sper
opens with several short, but to-the-point chapters on the history of
the study of charophytes of the Iberian
Peninsula, on the ecology of the cha-
rophytes, on methods of management
and conservation, on their value, and
the phylogeny and general morphol-
ogy of charophytes.
The authors take great delight in
their field of study and their enjoy-
Sment is obvious in the treatment of
the historical figures of the disci-
pline of Iberian charophytes. Honor
is paid to the early experts of the field,
but with some lighthearted over-
tones. The first general study of the
Iberian charophytes was published in
1910 by Dr. Eduardo Reyes Pr6sper,
entitled "Las Carofitas de Espafia.
Singularmente las que crecen en sus
estepas." Other notable experts in-
Seluded in the short historical sketch
are Adriano Gongalves da Cunha and

5th International Weed Science Congress Aquatic Weed Control Session
The 5th International Weed Science Congress took place
during the week of June 22nd, 2008 in Vancouver, Canada, and
was co-hosted by the International Weed Science Society, the
Canadian Weed Science Society, and the Weed Science Society
This meeting is held every four years and over 500 meeting
delegates from 46 countries represented academia, government,
non-governmental organizations, and private industry research. A
main topic session on aquatic weed control was co-organized by
Dr. Michael Netherland, US Army ERDC, USA, and Dr. Kevin
Murphy, University of Glasgow, Scotland. Invited talks were giv-
en by Dr. Sidnei Thomaz (Brazil) on the spread of invasive plants
in Brazilian reservoirs and Dr. Mic Julien (France) on water hya-
cinth dynamics and biocontrol in Lake Victoria, Africa. Papers se-
lected for oral presentation included: 1) Dr. Pat Chambers (Cana-
da) on worldwide distribution of aquatic macrophytes; 2) Dr. Joe
Caffrey (Ireland) on lagarosiphon invasion in Irish lochs; 3) Mr.
Jeff Schardt (USA) on the linkage between operational aquatic
plant control and research in Florida; 4) Dr. John Madsen (USA)
on Eurasian watermilfoil eradication efforts in Idaho; 5) Dr. Rob
Richardson (USA) on the use ofALS inhibitors for aquatic plant
control in the United States; 6) Dr. Matthew O'Hare (UK) on
issues with aquatic plants and water conveyance in rivers; 7)
Dr. Michael Smart (USA) on integrating ecological principles in
aquatic plant control efforts; 8) Ms. Pauline Lang (UK) on dis-
tribution of native and invasive plants in Zambia, Africa; 9) Dr.
Robinson Pitelli (Brazil) on control of invasive aquatic grasses in
Brazil; and 10) Dr. Cody Gray (USA) on control of aquatic mac-
rophytes in irrigation canals. There were also numerous posters
presented as part of this session. Other papers on aquatic weeds
were presented in different sessions throughout the conference.

The International Weed Science Society (IWSS) is a worldwide
scientific organization that was formed in 1975 by individuals
from Europe, North America, South America, and the Asian-
Pacific area to deal with global weed science issues. The forma-
tion of IWSS was promoted actively by the six existing regional
weed science societies (Asian-Pacific, European, Latin American,
American, East and West African). The Society has held highly
successful International Weed Control Congresses in Australia
(1992), Denmark (1996), Brazil (2000), South Africa (2. '14), and
Vancouver, Canada (2008).
Podostemaceae range worldwide on all continents with tropical
climates. Most of the members occur in tropical and subtropical
rivers and waterfalls. Many of the c. 48 genera and c. 280 spe-
cies are endemic to small geographical areas or even a single
river or waterfall. This website contains drawings of all African
species, photographs of African podos, keys, and a literature list,
together with much more information: Rutishauser R., Pfeifer

Mare's-tail in Colorado Waters
Hippuris vulgaris (Hippuridaceae) occurs in the southwestern and northern
USA, including Alaska. This population was found at high elevation (around
8,800') in San Miguel County in western Colorado. Currently residing with
a native milfoil, it is becoming a problem in this pond. Mare's-tail is consid-
ered endangered or threatened in some states.
