Emersed plants are plants that grow out of the water (or during
low-water times, in exposed sediments). They are rooted to the bottom,
but their stems, leaves and flowers are above the water
Lizard's-Tail
(Saururus cernuus)- Lizard's-tail is a common emersed plant. It
grows into small colonies from underground runners. The erect plant is
commonly found growing to one to two feet tall, in freshwater marshes
and swamps nearly throughout Florida. It blooms in the summer. Saururus
cernuus occurs almost always under natural conditions in wetlands.
Lizard's-tail has a bottlebrush spike of white flowers. It is typically
six to eight inches long but can be longer. The flower spike arches
above the leaves of the plant. After maturity, the flowers become a
string of nutlets that resemble a lizard's tail. The leaves are medium
sized, about 1 1/2 inches wide, and three to four inches long. They can
be arrowhead-shaped or heart-shaped, are on stalks, and are alternate on
the stem. Leaf stalks form clasps where they join the stem.
Pickerelweed
(Pontederia cordata)- The native pickerelweed is a very common emersed
plant that is commonly found growing in streams, marshes, ditches, ponds
and lake margins nearly throughout Florida. It is a prolific grower that
can cover large areas. Pontederia cordata blooms from spring to summer.
Pickerelweed typically grows to about two to three feet tall. Its leaves
are large, up to five inches wide, and are usually twice as long. Leaf
shapes are variable, but are usually lance-shaped. The easiest way to
recognize pickerelweed is by its spike of violet-blue flowers. Sometimes
the flowers are white.
Smooth
Water Hyssop (Bacopa monnieri)- Smooth water hyssop is an
emersed plant. This small sprawling herb is common in fresh and brackish
waters. At least three species of bacopa are native to Florida. This
species, smooth water hyssop, is distinguished by its white flowers, and
is distributed throughout the southernmost U.S. Smooth water hyssop
leaves are succulent and relatively thick. Its leaves are only 1/8 inch
wide and 5/8 inch long. Leaves are oblanceolate, and are arranged
oppositely on the stem. Flowers are small and white, with 4 or 5 petals.
Spatterdock
(Nuphar lutea subsp. advena)- Spatterdock is a large plant whose leaves
are often floating, however submersed and emersed leaves are common.
Spatterdock commonly occurs in ponds, lakes and sluggish streams and
blooms from spring to summer. Spatterdock has large heart-shaped leaves,
usually with wavy margins. Spatterdock floating leaves are attached to
long, stout stems which arise from large, spongy rhizomes. Spatterdock
submersed leaves are very thin, attached at the bottom rhizomes.
Spatterdock flowers are yellow and "half-opened" at or above the water
surface. Flowers are attached to thick round stems that are often six
feet long.
Swamp
lily (Crinum americanum)- Swamp lily is an emersed plant that
is frequently found growing in swamps, marshes, and wet hammocks. It is
a fragrant native. There are four species of
Crinum in Florida. The swamp lily is a perennial herb with an onionlike
bulb. The leaves are erect to spreading. Leaves are straplike, to three
feet long. The leaves are to three inches wide. Swamp lily flowers arise
from the bulb on a long flower stalk that is separate from the leaves.
The flowers have six petals and are white or white and pink.
Water-Spider
Orchid (Habenaria repens)- The water-spider orchid is an
emersed plant. It is a true native orchid. Water-spider orchid occurs on
marshy shores and sometimes in floating mats of vegetation. There are
five species of Habenaria in Florida. The water-spider orchid spreads
by runners as well as seeds. It is erect, growing to one or two feet
tall. Its leaves are thick and succulent, two to nine inches long and up
to one inch wide. The leaves are narrowly lance-shaped, tapering to a
narrow point. The most conspicuous part is its stalk of flowers that
occurs at the top of the plant. The small flowers are pale green, to 3/4
inch across. The petals are narrow, making the flowers resemble small
green spiders.
Waterpod (Hydrolea
quadrivalvis)- Waterpod is not especially common, but is native from
Virginia to Florida to Louisiana. Four species of Hydrolea exist in
Florida. This particular species grows in the shallow waters of swamps
and marshes from the northern counties south to the central peninsula of
Florida; it flowers in the summer. Waterpod is a medium-sized plant with
blue axillary flowers and stout thorns. Don't grab it without looking
first. Its thick stems are covered with very visible hairs.
