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. Members of this genus have holocentric chromosomes and have become a model for the study of chromosome evolution and meiotic recombination in holocentric plants. The genomes of '' Rhynchospora pubera'', '' R. breviuscula'', and '' R. tenuis'' have been published in 2022.

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 populations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
