Proserpinaca palustris, the marsh mermaidweed or common mermaid-weed, [2] [3] is a species of flowering plant in the watermilfoil family (Haloragaceae). It is found in North America, the Caribbean, and Central America. [3]
It has submerged leaves, which are sessile, 2–6 cm (1–2 in) long. They are deeply divided into linear segments and the emergent leaves are simply serrated. It has fruits with concave sides and sharp or winged angles. [4]
There are two know varieties; P. palustris var. palustris - which has fruits 4-6mm wide, angles wing margined, very rare SE and NW P. palustris var. crebra (Fernald and Griscom) - which has fruits 2-4mm wide, angles not winged, occasional E and NW [4]
It grows in swamps, bogs, ponds and marshes. [4]
Acer campestre, known as the field maple, is a flowering plant species in the family Sapindaceae. It is native to much of continental Europe, Britain, southwest Asia from Turkey to the Caucasus, and north Africa in the Atlas Mountains. It has been widely planted, and is introduced outside its native range in Europe and areas of USA and Western Australia with suitable climate.
The longleaf pine is a pine species native to the Southeastern United States, found along the coastal plain from East Texas to southern Maryland, extending into northern and central Florida. It reaches a height of 30–35 m (98–115 ft) and a diameter of 0.7 m (28 in). In the past, before extensive logging, they reportedly grew to 47 m (154 ft) with a diameter of 1.2 m (47 in). The tree is a cultural symbol of the Southern United States, being the official state tree of Alabama. Contrary to popular belief, this particular species of pine is not officially the state tree of North Carolina.
Prunus virginiana, commonly called bitter-berry, chokecherry, Virginia bird cherry and western chokecherry, is a species of bird cherry native to North America. The natural historic range of P. virginiana includes most of Canada, most of the United States, and northern Mexico.
Caltha palustris, known as marsh-marigold and kingcup, is a small to medium size perennial herbaceous plant of the buttercup family, native to marshes, fens, ditches and wet woodland in temperate regions of the Northern Hemisphere. It flowers between April and August, dependent on altitude and latitude, but occasional flowers may occur at other times.
The genus Parnassia, also known as grass of Parnassus or bog-stars, are plants now placed in the family Celastraceae., formerly classified in Parnassiaceae or Saxifragaceae. The plants occur in arctic and alpine habitats, as well as in dune systems and fens, swamps, wet meadows, open seepage areas, moist woods, and across the Northern Hemisphere. It is actually not a grass, but an herbaceous dicot. The stalk of the plant can reach up to 8 inches (200 mm), the leaves up to 4 inches (100 mm) and the petals can be up to 1.4 inches (36 mm) wide. The flower has five white petals with light green venation. There are five three-pronged sterile stamens, each tipped with drop-like, false nectaries, which attract pollinating flies and bees.
Caltha is a genus of rhizomatous perennial flowering plants in the family Ranunculaceae, to which ten species have been assigned. They occur in moist environments in temperate and cold regions of both the Northern and Southern Hemispheres. Their leaves are generally heart-shaped or kidney-shaped, or are characteristically diplophyllous. Flowers are star shaped and mostly yellow to white. True petals and nectaries are missing but the five or more sepals are distinctly colored. As usual in the buttercup family there is a circle of stamens around free carpels.
Rudbeckia fulgida, the orange coneflower or perennial coneflower, is a species of flowering plant in the family Asteraceae, native to eastern North America.
Triglochin maritima is a species of flowering plant in the arrowgrass family Juncaginaceae. It is found in brackish marshes, freshwater marshes, wet sandy beaches, fens, damp grassland and bogs. It has a circumboreal distribution, occurring throughout the northern Northern Hemisphere. In the British Isles it is common on the coast, but very rare inland.
The marsh rabbit is a small cottontail rabbit found in marshes and swamps of coastal regions of the Eastern and Southern United States. It is a strong swimmer and found only near regions of water. It is similar in appearance to the eastern cottontail but is characterized by smaller ears, legs, and tail.
Epipactis palustris, the marsh helleborine, is a species of orchid native to Europe and Asia.
Senecio congestus, also known by its common names swamp ragwort, northern swamp groundsel, marsh fleabane, marsh fleawort, clustered marsh ragwort and mastodon flower, a herbaceous member of the family Asteraceae and the genus Senecio, can be seen most easily when its bright yellow umbel flowers appear from May to early July standing 3 to 4 feet along marshes, stream banks and slough areas where it likes to grow.
Frankenia pauciflora, the common sea-heath or southern sea-heath, is an evergreen shrub native to southern Australia. It is part of the Frankenia genus of the Frankeniaceae family.
Lathyrus palustris is a species of wild pea known by the common name marsh pea. It is native to Europe, Asia, and North America. It is a perennial herb with leaves made up of oval-shaped or oblong leaflets a few centimeters long. It has branched, coiled tendrils. The plant bears an inflorescence of two to eight pinkish purple pea flowers each up to two centimeters wide. The fruit is a dehiscent legume pod.
Mimetes hirtus is an upright, evergreen shrub of 1½–2 m high from the family Proteaceae. It has upright, overlapping, (broadly) lance-shaped leaves, without teeth, but with one thickened pointy tip. It has cylindric inflorescences topped by a pine apple-like tuft of pinkish-brownish, smaller and more or less horizontal leaves. The flowerheads are tightly enclosed by yellow, red-tipped bracts, only the 9–14 long red styles and the whitish silky tips of the perianth sticking out. It is primarily pollinated by the Cape sugarbird. It is an endemic species of the southwest of the Western Cape province of South Africa, and grows in wet zones at the base of south facing mountain slopes. Flower heads may be found from May to November, but peaks in July and August. The species has several vernacular names of which marsh pagoda seems to be used most.
Triglochin palustris or marsh arrowgrass is a species of flowering plant in the arrowgrass family Juncaginaceae. It is found in damp grassland usually on calcareous soils, fens and meadows. The species epithet palustris is Latin for "of the marsh" and indicates its common habitat. It has a circumboreal distribution, occurring throughout northern parts of the Northern Hemisphere. It can be found locally in the British Isles especially the north.
Rorippa palustris, marsh yellow cress, is a species of flowering plant in the family Brassicaceae. It is widespread and native to parts of Africa, and much of Asia, Europe and Eurasia, North America and the Caribbean. It can also be found in other parts of the world as an introduced species and a common weed, for example, in Australia and South America. It is an adaptable plant which grows in many types of damp, wet, and aquatic habitat. It may be an annual, biennial, or perennial plant, and is variable in appearance as well.
Sapindus saponaria is a small to medium-sized deciduous tree native to the Americas. Common names include wingleaf soapberry, western soapberry, jaboncillo, sulluku and manele and a'e (Hawaiian).

It is a small genus, comprising only two to three extant species, all of which are native to eastern North America and the West Indies. All species in this genus are found in aquatic or terrestrial wetland habitats.
