Instructions for
Collecting and Shipping Plant Specimens for Identification or Diagnosis

By Erdman West

Plant specimens for identification or plant parts for diagnosis of a

diseased condition must be chosen carefully and shipped properly so that

your specialist will be able to give you the desired information.

Small plants: Plants 15 inches or less in height should be sent in


Large plants: Specimens larger than 15 inches are unnecessary. Rep-

resentative portions should be selected for sending. Sections of stems, 12

to 15 inches long with the leaves attached are necessary. Buds, flowers and

fruits or as many of these as are available should always be sent. Leaves

and stems alone often are not sufficient for the identification of exotic

or native plants. Grasses without seed-heads cannot be identified. Notes

on the size and shape of the bulb, root or other underground parts should

be included.

Specimens of disease should include al ~s of'~the trouble from the

earliest symptoms to the final stages. ugh of plant parts should be

included for the identification of the t play or tHe name of the plant

should be given. Various samples shou ~ separate/ pieces of absorbent

paper. Speci-ens of different troubles sh be l fully labelled. When

all the leaves on a plant are wilted or dead, specimens of the roots and

lower trunk at the ground line should be sent. Diseased specimens should

always be generous.

Packing: Specimens should be wrapped in absorbent paper such as news-

paper, paper toweling, etc. Do not make the specimens wet as they are much

',-r- -


more satisfactory dry than when molded. They need not be pressed like

herbarium specimens. They may be packed fresh, as they are picked from

the plant. Each piece should be wrapped separately but all parts of the

same plant should be tied together. If more than one plant is involved,

number each and keep notes or duplicates for future reference so that we

do not have to return the specimens.

Specimens should be packed carefully in a container that will resist

breaking in transit. They may be placed in a mailing tube, a cardboard

box or between layers of stiff cardboard. Do not mail them on the week-

end. Be sure your name and return address are on the package.

A letter of explanation should always be mailed at the same time or

may be attached to the package. This letter should tell the reason for

sending the material, kind of trouble involved, source of specimens and

anything else of interest. It should tell how serious a trouble is,

acreage involved, previous treatments, such as sprays, soil treatments,


Plant specimens for identification should be addressed to Botanist,

Florida Agricultural Experiment Station, Gainesville, Florida. Specimens

of diseased plants should be sent to Plant Pathology Department at the

same address.
