(a) Abrus precatorius L., Rosary Pea, has seeds which are brilliant red
with a black spot. They are strung into necklaces, used for decoration
and played with by children. Potentially fatal internal toxins of vari-
able effect are present in all parts, notably in the seeds. The poisons
may be absorbed when taken internally or through a cut or puncture (as
when stringing beads).
(b) Melaleuca quinquenervia (Cav.) S. T. Blake, Paper-bark Tree or
Cajeput-tree, is an introduced tree native of Australia. The flowers
and at times the foliage, emit an aromatic substance which produces
respiratory disturbance for some persons. Sensitive persons may suffer
a burning rash from close contact with the bark or leaves.
(c) Datura X candida (Pers.) Saff., Angel's-trumpet, and other species
of Datura possess nervous system toxins in all parts, especially in the
flowers, nectar and seeds. Poisonings result from accidental ingestion
or from overdoses taken by persons seeking narcotic and hallucinogenic
effects from the plant. The fragrance of the flowers is found pleasant
by some persons, but produces discomfort for others.
(d) Toxicodendron radicans (L.) Kuntze, Poison Ivy, is a climbing vine
with variable trifoliate leaves. Most parts of the plant contain an
oily sap which causes severe skin irritation. The oil is spread only
by contact or is carried in smoke from the burning plant.
(e) Argemone mexicana L., Mexican Prickly-poppy, is a prickly plant
which may inflict skin injury. The seeds contain poisonous alkaloids.
They were once a problem as a contaminant in grain, flour and livestock
feed.
(f) Ricinus communis L., Castor Bean, produces brown and silvery mottled
seeds with toxins, allergens and the purgative, Castor Oil. Fatal poi-
soning of humans and animals has resulted from the ingestion of chewed
seeds. The plant may produce allergic responses such as eye irritation,
dermatitis and bronchial difficulty.

INTRODUCTION


The flora of Florida is an unusually diverse one within the contiguous
United States. It contains many species that are unique, being found only
there, and is further enriched and diversified by extensions of northern
and southern species that reach their extreme distribution limits in the
state. In addition, the salubrious climate enables cultivation of an
exceptionally diverse selection of fruits, vegetables, nuts, fiber plants,
ornamentals, and other cultivars of value to society and commerce. A minor
proportion of these plants is poisonous or irritant to humans and other
animals, but though the percentage is small the actual number is large
because the total is large. The purpose of this Guide is to consolidate
information on these plants, providing a reference work that gives informa-
tion about them and facilitates access to the literature. The plants
treated here are only the vascular plants; non-vascular plants, including
fungi, algae, mosses and their relatives are omitted.

Numerous other books and articles have been written about plant
poisoning, more than 630 of which are enumerated in the bibliography of
this volume, but there is no other comprehensive work for the toxic and
irritant plants of Florida. This Guide is a step toward complete survey
of the native, naturalized, introduced and cultivated plants of importance
in this regard. Although 500 entries are included, comprehensiveness

cannot be claimed and will not be possible until every plant kind in
Florida has been carefully studied and tested; the vast majority of species
remain essentially unknown. The user should be aware that many plants not
incorporated in this volume are potentially problematic, especially under
the special circumstances of particular situations or with unusually
susceptible persons or animals.

Similarly, this is not a work intended to give authoritative advice on
treatment. Data have been compiled from many sources, and are only as
trustworthy as those sources after interpretation by the authors. If
serious poisoning is suspected, seek competent medical help immediately.


HUMAN POISONING

Children, especially from the ages one to nine, are most frequently
poisoned from ingesting toxic plant materials. They sometimes eat the most
unpleasant and unlikely things out of curiosity or while at play. They are
also susceptible to "taking a dare" from a playmate, even when they themselves
and the child offering the dare suspect the possible danger. Parents and
educators should emphasize the foolhardiness of taking unnecessary risks
because of taunts, and should forbid eating unknown leaves, nuts or berries.

Adults are increasingly drawn back to nature, with greatly heightened
interest in the use of "natural" plants and weeds, especially for their
comestible and medicinal properties. Yet, many of the enthusiasts know
relatively little about the plants around them, and are heedless of the
dangers of ill-informed experimentation. Even rather innocuous plants that
are well-known can be harmful when used in novel ways; for instance, the
tomato and potato, both important and common food plants, produce poisonous
foliage and stems that have caused human poisoning and livestock deaths.
Always remember that most of the world's powerful, biologically produced
drugs, including tranquilizers, allergens, hallucinogens, stimulants,
depressants, and poisons, are plant products. In part, they are defense
mechanisms evolved to protect the plants against animal predation, and they
work. It is obvious that these mechanisms are especially potent and
effective for wild plants, plants that have not historically been found
edible, and that have not been made more palatable, nutritious and harmless
by selective breeding.

These remarks are not meant to discourage experimentation with wild
species. They do suggest, however, that intelligent and careful experimen-
tation will reduce the probability of accidental poisoning. As a first
step, learn to identify plants yourself (colleges and universities usually
provide plant identification courses), and be cautious with unknown plants.
Seek advice and guidance from people with experience, and familiarize
yourself with agencies that can provide assistance, including schools,
colleges, hospitals, clinics, and government agencies, such as your county
agricultural or extension agent.

LIVESTOCK POISONING

Livestock poisoning is different in many respects from human poisoning.
Humans are seldom forced to eat unusual foods by circumstances beyond their
control, and are likely to ingest relatively little and to know what they
have eaten. Animals often eat poisonous plants only when they are provided
inadvertently as fodder, or when starvation forces unusual grazing and
browsing. The animal cannot explain or comment upon its symptoms, nor can
it communicate information as to the plant or plants involved. Thus, while
humans can be educated to careful avoidance, animals must be protected from
harm by removing dangerous plants from the areas they occupy and in which
they forage, and by intelligent feeding by the farmer or keeper.


TREATMENT OF POISONING

Prevention is the best cure. Adults should know the hazards in their
homes, yards, and environs, and should educate themselves and their children
for intelligent behavior, including avoidance. Wild plants should be used
in medicine and cooking only when they are known with absolute certainty
to be innocuous. There are no easy rules to distinguish poisonous from
harmless and beneficial plants, and closely similar, sometimes related
species may be easily confused with tragic results.

If poisoning is suspected, consult a physician or the poison control
center of your local hospital immediately. When the plant is known, take
as good an example of it as you can to the treatment center so that it can
be identified exactly, and the nature of its toxic substances and the
effective treatments determined with precision. For herbaceous plants, try
to take an entire plant, with leaves, stems, flowers, fruits and roots,
or as complete a specimen as is available. If the plants are large, as
for trees and shrubs, take a large branch with several leaves, flowers and
fruits, and note carefully whether it appears to be cultivated or wild. It
is far better to have too large a specimen than one inadequate for deter-
mination.

If absolutely no professional help is available, it is usually helpful
to empty the stomach by induced vomiting (emesis). Give the sufferer a
glass or more of warm water, followed by mustard water, ipecac, or physical
gagging. After the stomach contents are emptied, a process that may require
several repeated vomits, the victim may benefit from administration of
soothing protective, such as flour mixed to the consistency of cream in
water, egg white, milk, or a suspension of activated charcoal in water.
Note that these treatments are different from those used in many kinds of
chemical poisoning, and they should not be confused. Not infrequently,
plant poisoning is accompanied by convulsions, and lavage and emesis should
never be attempted when convulsions are imminent or in progress because
the person may choke to death on liquids or vomit. In all cases, the
patient should be kept calm, and medical advice should be sought as quickly

as possible. Be alert to the symptoms of poisoning, and remember that they
may not be evident for several hours or days.

The authors of this Guide and its publishers have not tested the
treatments listed herein, and are in no way responsible for their efficacy
or failure. As stated above, treatment data have been garnered wholly from
the literature, and are provided for assistance to the professional physician
or veterinarian, trained to treat patients and animals suffering from poi-
soning or exposure to irritants, and capable of checking or extrapolating
from the information here.


HOW TO USE THIS GUIDE

The Guide is divided into six main sections. The organization of these
is described below:

1. Introduction.

2. Table of Florida Plants with Poisonous and Irritant Properties.

This section includes data in five columns:

A) Number. Each entry is numbered in the left-hand column, and the
numbers are used in the Index for ready location of plants and
data about them.

B) Names. The scientific name, consisting of the genus and species,
together with the author, are presented in large type. If the
species of a plant is questionable, or if several species of the
same genus are believed to have essentially identical properties,
the scientific name is given only as the generic name, followed
by "spp." Synonymous scientific names (names used in former times
or by other authors, necessary for literature access) are presented
in parentheses. Common names follow the scientific names, and are
not underlined.

C) Family Name and Literature References. In the third column, headed
"FAMILY (References)", the scientific name of the family is given
in large capitals, followed by the common name for the family in
smaller capitals. Numbered references are provided in parentheses,
and these numbers correspond to alphabetically arranged, numbered
references in the Bibliography.

D) Toxic Parts and Constituents. Here the known toxic parts and
materials are listed, reflecting reports in the literature cited.
The abbreviation "w/", means with, containing, or containss. A
question mark inside parentheses, (?), indicates the information is
uncertain. Words in parentheses are either other names given to




- 5 -


constituents, or are general terms for the chemical groups to
which a substance belongs, such as alkaloids, glycosides, proteins,
and pigments. The toxic parts and constituents of many plants are
unknown, and every part should be suspect if the plant is known
to be poisonous in any way.

E) Effects and Remarks. In the far right column, the code (NCHLPSD)
stands for the following:

N = Native or naturalized in Florida.

C = Cultivated in Florida as a crop, landscape plant, or
houseplant.

H = The plant or an extract has caused the death of humans.

L = The plant has caused the death of livestock or domestic
animals.

P = The plant has caused poisoning of humans and/or livestock
or domestic animals.

S = The plant is suspected of being poisonous, although the
supporting data are uncertain.

D = The plant is a cause of dermatitis (skin irritation)
allergy, eye irritation, and/or respiratory problems in
humans (and possibly some animals).

= A line above any of the letters means that the information
available is questionable.

Effects and remarks, including symptoms and treatments, complete
the right-hand column. All of the material that is indented, that
is, remains to the right of the (NCHLPSD) code, pertains particu-
larly to all the plants opposite the indentation. Remember that
symptoms vary greatly with the individual person or animal.
Symptoms in parentheses are thought to occur only occasionally.

3. Bibliography. The references in the bibliography are listed alpha-
betically and numbered sequentially for each letter group, permitting
unambiguous and brief identification in the table. Starred references (*)
include large numbers of species, and may be especially useful as general
references or for further research for the plants of Florida. A few
references added late, and out of alphabetical sequence at the end of a
particular letter group, have their alpha-numeric numbers compressed to
the right and preceded by a slash (e.g.,/M62, found after entry M27,
indicates a reference that should occur alphabetically as the 28th entry
under "M", but has been included as the 62nd entry).

4. List of Genera by Family. This compact list, organized alphabetically
by family, shows the nature of plant coverage in the work, and is helpful
to the specialist or amateur familiar with the nature and classification
of vascular plants.

5. Index. The Index includes common and scientific names listed alpha-
betically, with the numbers allotted them in the table. CAUTION: Common
names are inexact for plants, and may be applied to different species by
people with different cultural or geographic backgrounds.

6. Addendum. A few last-minute items that came to the authors' attention
after the body of the work was completed and typed.

with symptoms like those of acute poisoning, but
slower & milder in appearance. In either case,
recoveries are few. Poisonings in humans, includ-

ble atropine poisoning. No photosensitization
has occurred in humans, but the leaves cause con-
tact dermatitis. Gastric lavage should bring
about complete recovery, if performed in the first
