Calamagrostis is a genus of flowering plants in the grass family Poaceae, with about 260 species that occur mainly in temperate regions of the globe. Towards equatorial latitudes, species of Calamagrostis generally occur at higher elevations. These tufted perennials usually have hairless narrow leaves. The ligules are usually blunt. The inflorescence forms a panicle. Some may be reed-like.
Agrostis is a large and very nearly cosmopolitan genus of plants in the grass family, found in nearly all the countries in the world. It has been bred as a GMO creeping bent grass.

Achnatherum is a genus of flowering plants in the grass family, Poaceae. It includes 20 species of needlegrass native to temperate Eurasia and North Africa. Several needlegrass species have been switched between Achnatherum and genus Stipa; taxonomy between the two closely related genera is still uncertain. In 2019 Peterson et al. reorganized the genera in tribe Stipeae based on molecular DNA studies, and placed the species from the Americas into other genera.
Elymus is a genus of perennial plants with approximately 150 species in the grass family, related to rye, wheat, and other widely grown cereal grains.
Chloris is a widespread genus of monophyletic grasses belonging to the family Poaceae, known generally as windmill grass or finger grass. The genus is found worldwide, but especially in the tropical and subtropical regions, and more often in the Southern Hemisphere. The species are variable in morphology, but in general, the plants are less than 0.5 m in height. They bear inflorescences shaped like umbels, with several plumes lined with rows of spikelets. The genus is characterized by the series of sterile florets above the lowest fertile ones, spikes usually 4–10 in numbers, approximated or in a slightly separated series of 10–20 spikes, rarely an indefinite numbers of terminal spikes. In India, 11 species are known to occur in which only two are endemic viz. Chloris wightiana Nees ex Steud. and Chloris bournei Rangachariar & Tadulingam.
