Let's say you're out walking in the
woods in May and you see a plant with bright yellow
flowers with leaves that are lance shaped at the base,
green in color with purple stripes throughout. There are
a lot of these around you. What is this plant?
Well, you sit down beside the plant
and start studying it and you notice that it is anywhere
from 4 to 12 inches tall. The stem is slender and there
are two leaves that are from 2 to 3 inches long and
about 1 inch wide. They are opposite from each other.
The flower is lily-like; about an
inch across and bright yellow, with 6 petals that curve
back (reflexed). The flowers are also nodding (bent
downward). The flowers are also purple blotched on the
outside of the petals. As you continue to look and the
day turns to evening, they close up for the night.
The area that you're in is moist and
wooded and the light is filtered.
You also see many, many single leaves
protruding from the forest floor that are the same as
the ones that have two leaves and flowers on them and
realize that these must be younger plants.
Close by you see a plant that you
recognize as Cut-Leaved Toothwort; but what is this one?
So how do you find out what this plant is?
There are many ways to find the
identity of the plants you see in the wild. Many people
just try to remember what the flower looks like then
flip through illustrated guides and look at the pictures
for a match. This is tedious but it can work well for
very distinct, showy plants. Others take field guides
into the field. The technique sounds appropriate but I
find that one can spend hours on a single plant and then
often not positively identify it. Making some notes and
a quick sketch takes only a few moments. Then one can
move on to find other flowers and take back a permanent
record of the plants to use later to identify them.
Bringing home notes and then reviewing them with
reference books in hand is a great way to prolong the
enjoyment of an outdoor experience and it gives you
unlimited time to make an identification.
Very localized plants may not appear
in general guides. I have had plants in my notes for
years before discovering their identity. Who knows, you
may find an unknown species or a rare variant. That is a
good reason to include the exact date, time, habitat and
location in your notes. Remember that many plants are
only above ground for a brief period and some only bloom
at a certain time of day or for only a few days.
First - we need to make sure that we
remember what it looks like. You can dig one up (only if
there are a lot there); You can photograph it; You can
draw it and write down the description of the plant; or
you can look at all parts of the plant so that you can
get a good identification. Also, learn what each part is
called.
Then, we can look it up in a good
field guide. Try:
1) Peterson's Field Guide to
Wildflowers: Northeastern and North Central North
America.
2) Newcomb's Wildflower Guide. (This
one is very good and simple at identifying flowering
plants)
3) A Field Guide to Edible Wild
Plants: Eastern and Central North America.
4) Peterson's Field Guide to
Eastern/Central Medicinal Plants.
5) National Audubon Society Field
Guide to North American Wildflowers.
If you don’t have or can’t find a
field guide, find someone in your area that is
knowledgeable on wild flowers, like a Garden club,
Naturalist, Botanist from a local college, or State
Department of Natural Resources personnel. You could
also Search the internet for sites on plant
identification.
To make identification easier, learn
to key out a plant.
