Rhynchospora Tenuis
''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.
