Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus ''Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinkhole
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are locally also known as ''vrtače'' and shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. A ''sink'' or ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture surf ...

Apocynum
''Apocynum'', commonly known as dogbane or Indian hemp, is a small genus of the flowering plant family Apocynaceae. Its name comes from Ancient Greek , from "away" and "dog", referring to dogbane ('' Cionura erecta''), which was used to poison dogs. The genus is native to North America, temperate Asia, and southeastern Europe. ''Apocynum'' species are used as food plants by the larvae of some Lepidoptera species, including the mouse moth and the queen butterfly. Uses ''Apocynum cannabinum'' was used as a source of fiber by Native Americans. '' Apocynum venetum'' () is used as an herbal tea in China. Dogbane contains cymarin, a cardiotonic agent formerly used to treat cardiac arrhythmia in humans. Species Almost 300 names have been proposed in the genus for species, subspecies, and forms. , only the following five species and hybrids are currently recognized, with several subspecies and varieties accepted for '' A. androsaemifolium'' and '' A. venetum'' (see their respecti ...

Ilex Verticillata
''Ilex verticillata'', the winterberry, is a species of holly native to eastern North America in the United States and southeast Canada, from Newfoundland west to Ontario and Minnesota, and south to Alabama. Other names that have been used include black alder, Canada holly, coralberry, fever bush, Michigan holly, or winterberry holly. The species occurs particularly in wetland habitats, but also on dry sand dunes and grassland. The berries are an important food resource for some species of bird, among them the American robin. Description ''Ilex verticillata'' is a shrub growing to tall. It is one of a number of hollies which are deciduous, losing their leaves in the fall. In wet sites, it will spread to form a dense thicket, while in dry soil it remains a tight shrub. The leaves are glossy green, long, broad, with a serrated margin and an acute apex. The flowers are small, in diameter, with five to eight white petals. The fruit is a globose red drupe in diameter, which of ...

Triadenum Virginicum
''Hypericum virginicum'' (''Triadenum virginicum''), the marsh St. Johns-wort or Virginia marsh St. Johnswort, is a species of flowering plant in the family Hypericaceae. It is native to the central and eastern United States and eastern Canada. ''Hypericum virginicum'' is a small herbaceous plant growing up to in height. Its leaves are sessile and opposite, sometimes clasping. The flowers grow up to in diameter, with 5 pink petals. It flowers in the summer to early fall and grows in bogs, wet meadows, fens, swamps, and along lakeshores. It can be distinguished from the closely related '' Hypericum fraseri'' by its longer, acute sepals, and longer styles. Alexander Garden first observed this plant in 1754, but following correspondence with Jane Colden realized that she had previously collected and recorded the same species in 1753, one year before his discovery. As such, Jane Colden held naming rights for what both naturalists thought would be a newly described genus. Colden ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sensu Lato
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case).
