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.

Rhynchospora Alba
''Rhynchospora alba'', the white beak-sedge, is a plant in the sedge family, Cyperaceae. It is a tufted herbaceous perennial around 50 cm tall, with white inflorescences that flower in August. The fruit of the sedge is a small achene with a characteristic beak-like cap. It is dispersed by wind or falls by gravity, leading to individuals existing in tight clumps. The species favours wet, acidic and nutrient poor soils, thriving in ''Sphagnum''-dominated bogs, but also peaty grasslands. As such it is often used as a positive indicator for bog and mire ecosystem health. The species was first described by Linnaeus in 1753 under a different genus and name, ''Schoenus albus'', but was subsequently reclassified into the novel genus '' Rhynchospora'' by Vahl in 1805. It has a wide range across the Northern Hemisphere, extending from the inland wetlands of North America, across Europe to the Korean Peninsula. Due to this large range, there is considerable variation between population ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhynchospora Knieskernii
''Rhynchospora knieskernii'' is a rare species of sedge known by the common name Knieskern's beaksedge. It is endemic to the state of New Jersey in the United States, where it occurs naturallyin the Pine Barrens. Reports have cited it present in Delaware as well, but these populations appear to have been introduced. It is threatened by the destruction and degradation of its habitat. It is a federally listed threatened species of the United States. This perennial sedge produces clumps of very narrow, triangular stems lined with thin leaves. Inflorescences occur at the tips and on the sides of the stems. Each contains two to four tight clusters of dark brown spikelets and leaflike bracts.''Rhynchospora knieskernii''.
