Cypress Dome
A cypress dome is a type of freshwater forested wetland, or a swamp, found in the southeastern part of the United States. They are dominated by the ''Taxodium spp''., either the bald cypress (''Taxodium distichum''), or pond cypress (''Taxodium ascendens''). The name comes from the dome-like shape of treetops, formed by smaller trees growing on the edge where the water is shallow while taller trees grow at the center in deeper water. They usually appear as circular, but if the center is too deep, they form a “doughnut” shape when viewed from above. Cypress domes are characteristically small compared to other swamps, however they can occur at a range of sizes, dependent on the depth. Cypress domes form when pond cypress grow in shallow standing water. The ground level in the center of the dome may be several inches to a few feet lower than at the edge of the dome, but tree growth is more vigorous at the center of the dome. Thus, the treetops are higher at the center than at the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

Big Cypress National Preserve
Big Cypress National Preserve is a United States National Preserve located in South Florida, about 45 miles (72 kilometers) west of Miami on the Atlantic coastal plain. The Big Cypress, along with Big Thicket National Preserve in Texas, became the first national preserves in the United States National Park System when they were established on October 11, 1974. In 2008, Florida film producer Elam Stoltzfus featured the preserve in a PBS documentary. Big Cypress borders the wet freshwater marl prairies of Everglades National Park to the south, and other state and federally protected cypress country in the west, with water from the Big Cypress flowing south and west into the coastal Ten Thousand Islands region of Everglades National Park. History Archaeology at Platt Island in the preserve shows humans settled there more than two thousand years ago. The Calusa people had an extensive presence in the area when Europeans arrived. Big Cypress was historically occupied by variou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lemna
''Lemna'' is a genus of free-floating aquatic plants referred to by the common name "Lemnoideae, duckweed". They are morphologically divergent members of the arum family Araceae. These rapidly growing plants have found uses as a Model organism, model system for studies in community (ecology), community ecology, basic plant biology, ecotoxicology, and production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture. Currently, 14 species of ''Lemna'' are recognised. Taxonomy These duckweeds were previously placed in a separate flowering plant family, the Lemnaceae, but they are now considered to be members of the Araceae. Description ''Lemna'' species grow as simple free-floating Thallus (tissue), thalli on or just beneath the water surface. Most are small, not exceeding 5 mm in length, except ''Lemna trisulca'', which is elongated and has a branched structure. ''Lemna'' thalli have a single root, which distinguishes this genus from the rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodwardia
''Woodwardia'' is a genus of ferns in the family Blechnaceae, in the suborder Aspleniineae (eupolypods II) of the order Polypodiales. Species are known as chain ferns. The genus is native to warm temperate and subtropical regions of the Northern Hemisphere. They are large ferns, with fronds growing to 50–300 cm long depending on the species. The fossil record of the genus extends to the Paleocene. Taxonomy ''Woodwardia'' was first described by James Edward Smith in 1793. It was named after Thomas Jenkinson Woodward. When broadly circumscribed, the genus contains about 15 species (plus some hybrids). In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the genera '' Anchistea'' and '' Lorinseria'' (each with one species) are kept separate.

Osmunda Regalis
''Osmunda regalis'', or royal fern, is a species of deciduous fern, native to Europe, Africa and Asia, growing in woodland bogs and on the banks of streams. The species is sometimes known as flowering fern due to the appearance of its fertile fronds. Names The name ''Osmunda'' possibly derives from ''Osmunder'', a Saxon name for the god Thor. The name "royal fern" derives from its being one of the largest and most imposing European ferns. The name has been qualified as "old world royal fern" in some American literature to distinguish it from the closely related American royal fern, '' O. spectabilis''. However this terminology is not found in British literature. Description ''Osmunda regalis'' produces separate fertile and sterile fronds. The sterile fronds are spreading, tall and broad, bipinnate, with 7-9 pairs of pinnae up to long, each pinna with 7-13 pairs of pinnules 2.5-6.5 cm long and 1–2 cm broad. The fertile fronds are erect and shorter, 20–50 cm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saururus Cernuus
''Saururus cernuus'' (lizard's tail, water-dragon, dragon's tail, swamp root) is a medicinal plant, medicinal and ornamental plant native to eastern North America. It grows in wet areas or shallow water, and can be up to about a meter tall. The native range covers much of the eastern United States, as far west as eastern Texas and Kansas, south to Florida, and north to Michigan and New York state. ''Saururus cernuus'' also occurs in Ontario Canada. It is an obligate wetland plant and able to grow in saturated soils. ''Saururus cernuus'' is a herbaceous perennial that gets its most frequent common name, lizard's tail, from its white flowers that bloom in the summer months. The inflorescence is usually 6 to 8 in long. After floral maturity the white flowers turn brown, giving the plant its namesake, lizard's tail. The leaves are usually heart-shaped, arrow-shaped, or lance-shaped, and are arranged alternately on the stem. When the leaves are crushed they release a citrus or sassafr ...

Rhynchospora
''Rhynchospora'' (beak-rush or beak-sedge) is a genus of about 400 species of sedges with a cosmopolitan distribution. The genus includes both annual and perennial species, mostly with erect 3-sided stems and 3-ranked leaves. The achenes bear a beak-like tubercule (hence the name “beak-rush”, although the plants are sedges, not rushes) and are sometimes subtended by bristles. Many of the species are similar in vegetative appearance, and mature fruits are needed to make a positive identification. The inflorescences (spikelets) are sometimes subtended by bracts which can be leaf-like or showy. Ecology ''Rhynchospora'' occurs on all continents except Antarctica, but is most diverse in the neotropics.Thomas, W.W. 1992. A synopsis of ''Rhynchospora'' (Cyperaceae) in Mesoamerica. ''Brittonia'' 44:14–44. It is most frequent in sunny habitats with wet, acidic soils.Kral, R. 2002. ''Rhynchospora''. In: Flora of North America Editorial Committee, eds. 1993+.

Polygonum
''Polygonum'' is a genus of about 130 species of flowering plant in the buckwheat and knotweed family Polygonaceae. Common names include knotweed and knotgrass (though the common names may refer more broadly to plants from Polygonaceae). In the Middle English glossary of herbs ''Alphita'' ( 1400–1425), it was known as ars-smerte. There have been various opinions about how broadly the genus should be defined. For example, buckwheat (''Fagopyrum esculentum'') has sometimes been included in the genus as ''Polygonum fagopyrum''. Former genera such as ''Polygonella'' have been subsumed into ''Polygonum''; other genera have been split off. The genus primarily grows in northern temperate regions. The species are very diverse, ranging from prostrate herbaceous annual plants to erect herbaceous perennial plants. ''Polygonum'' species are occasionally eaten by humans, and are used as food plants by the larvae of some Lepidoptera species – see list. Most species are considered weeds i ...
