General Information- Flora
Protists, Fungi, Vascular and Non-Vascualar Plants
Flowering Dogwood (Cornus florida)
Purpose
Right off the bat I want to acknowledge that I am
no expert on plants and flora. The purpose of this section is mostly
to showcase some of the species that may be encountered in New York State.
Information is provided on each species, and is accurate to the best of
my knowledge. If there are any mistakes I hope you will
let
me know.
Species
There are literally hundreds of Protists, hundreds
of Fungi, and thousands of Vascular and Non-Vascular Plants known from
New York State. These include mushrooms, ferns, slime molds, trees,
flowers, grasses, horsetails, club mosses, algae, lichens, and more.
Many are small or nondescript, but some such as cattails and a variety
of tree species are very common and form the basis for their various ecosystems.
In fact, most ecosystems are defined by the plant life they hold.
Without plants and the like no animal species would exist in the state.
Some animals are dependant on one or two species of plants and form intense
symbiotic relationships.
The flora of the state is important in that it regulates
weather patterns, slows erosion, removes toxins from the ecosystem, and
has great economic value as timber and cropland. Many of the trees
in the area lose their leaves in winter as an adaption to cold weather
and the associated color change draws many tourists to the area.
Flowers
Flowers are the most easily recognized parts of
most plants. They usually consist of petals and sepals,
petals being the main part of the flower and colorful and soft. Sepals
are normally green and encircle the petals as a base. In some flowers,
such as irises and orchids the sepals are colored similar to the petals
and form a major part of the flower. There may be a sterile bract
which is a modified leaf framing the flower. Dogwood "flowers" actually
consist of the bract surrounding a cluster of small inconspicuous flowers.
Flowers are classified into three main groups. Regular
flowers, such as the buttercup and lily family, have a radially symmetrical
group of equal sized petals. Irregular flowers are characterized
by unequal parts that are bilaterally symetrical. Peas, orchids,
and violets are examples of irregular flowers. Composite flowers
include asters and goldenrods and are made up of several small
disk
florets with small equal petals. The disk florets are then surrounded
by a ring of ray florets which have an enlarged petal. The
overall impression is of one complex flower.
No matter which group they are, flowers are the
reproductive part of the plant. They are most commonly pollinated
by insects, but some are pollinated by birds and others by wind.
Insect pollinated flowers tend to be large enough to give the insect a
place to land and are usually yellow, orange, or white to be easily visible.
Bird pollinated flowers are often red and have a long tube containing nectar
that is innaccesible to bees and other insects. Wind pollinated flowers
tend to be small and inconspicuous. Many lack petals altogether.
The pollen producing part of flowers (considered
the male part) are the stamens, consisting of a long filament
and the anther. The anther produces pollen which is
then picked up by a pollinator and carried on to the next flower.
The pistil is the female part of the flower and it accepts the pollen.
The swollen base of the pistil contains the ovaries which produce
the seeds and the fruit.
Flowers are classified as perfect or imperfect.
Perfect
flowers have both male and female parts in one flower. Imperfect
flowers have only male or only female parts. Some plants with
imperfect flowers have both male and female flowers on one plant.
These are termed diecious. Those species with only one sex
flower on the plant are monecious.
Groups
There are literally thousands of protists, fungi,
algae, and vascular plants in New York State. This lists only those
species which I have write-ups and photographs. I don't know a lot
about about the taxonomy of plants and the like, so what is listed is only
a basic overview of what I know. If you find any mistakes or inaccuracies
email
me.
Kingdom Protista - Protists
Phyla Myxomycota and Acrasiomycota- Slime Molds
Slime molds are a much misunderstood group. There is still much debate
as to whether they belong in the kingdom with the one-celled protists or
the fungi. They are now considered protists. Slime molds grow
in damp areas and can either be pretty and colorful or gross and disgusting.
Most commonly slime molds spend their time below ground as single cells
feeding on decaying plant matter. Every now and then the cells congregate
to form spores that develop into new slime molds. This phase of their
life is the most visible and weird. Occasionally, slime molds will
move across land searching for better breeding grounds. They move
across the ground in an amoeboid blob like the "B" rate horror movies of
the 1950's and 60's.
Kindom Fungi- Mushrooms and kin
Mushrooms and other fungi, along with slime molds and
bacteria, are the decomposers of the natural world. They change dead
and dying biological material into forms that other life can use.
Most plants are dependant upon a symbiotic fungus in their roots to grow.
The fungus converts the soil into raw nutrients and elements that the plant
then uses to grow. These are called mycorrhizal associations.
Although fungi are much more common in their unicellular phases they are
most commonly seen in their reproductive stage. Most fungi spend
their life as an underground net-like mass of cells spreading far and wide
absorbing nutrient from their substrate. When they begin their reproductive
cycle they grow in dense clusters that push above ground and are known
as mushrooms. These reproductive structures release microscopic spores
which are carried by the wind and develop into new fungus.
Although many mushrooms are edible, many poisonous
mushrooms resemble edible ones. No one should eat wild mushrooms
except those well versed in the species.
Kingdom Plantae- Plants
Ferns are primitive plants that don't produce seeds. Instead they
release spores into the air similar to the way mushrooms reproduce.
The spores are contained in tiny sacs called sporangia. Several
sporangia grouped in a pattern form a sori. The sori in turn
may be spread out randomly on the underside of the leaf, or in spots and
patterns. These patterns can help to identify ferns in the field.
The stem of a fern grows along the ground as a rhizome
and from this sprout the leaves. Most fern leaves are divided once
(pinnate), twice, (bipinnate) or three times (tripinnate.)
These divisions are referred to as leaflets.
Young leaflets arise in a curled position.
The young leaves are called "fiddleheads" and some species may be edible
while others are deadly.

Flowering plants are one of the most diverse groups on the planet.
Although many are large and showy, others are small and inconspicuous and
seldom observed. I have opted to include only the most common, interesting,
or easiest observed plants in New York state. For a discussion of
flowers and flower parts see the preceding sections.
