Genera
Arrhenatherum
Arrhenatherum, commonly called Oat-grass or Button-grass, is a genus with seven species and subspecies from the grass family Poaceae. It grows in Europe and the Mediterranean. Wild forms resemble Wild Oat (Avena) or Fescue (Festuca). Meadow Oat-grass is also found on some alvar formations such as the Stora Alvaret of Oland, Sweden. [more]
Avena
The oats (Avena) are a genus of 10-15 species of true grasses (family Poaceae). They are native to Europe, Asia and northwest Africa. One species is widely cultivated elsewhere, and several have become naturalized in many parts of the world. All oats have edible seeds, though they are small and hard to harvest in most species. [more]
Deschampsia
Deschampsia is a genus of wild plant in the grass family Poaceae, commonly known as hair grass or tussock grass. There are 30 to 40 species. [more]
Helictotrichon
Helictotrichon is a genus of in the Poaceae family. It contains the following species: [more]
Koeleria
Koeleria is a genus of true grasses which includes species known generally as Junegrasses. The genus was named after German botanist Georg Ludwig Koeler. [more]
Trisetum
Perennials, tufted, sometimes shortly rhizomatous. Leaf blades narrowly to broadly linear, usually flat; ligule membranous. Inflorescence a moderately lax to spikelike panicle, shining. Spikelets with 2 or 3 florets, disarticulating below each floret; rachilla shortly bearded, extended beyond uppermost floret, tipped by a reduced or vestigial floret; glumes lanceolate, unequal or subequal, shorter than spikelet, keeled, herbaceous or membranous, margins broad, hyaline, lower glume 1(-3) -veined, upper glume 3-veined, apex acute or acuminate; floret callus glabrous or shortly bearded; lemmas lanceolate, laterally compressed, membranous to thinly leathery, 5-veined, glabrous, awned from above middle of back, apex 2-toothed, teeth often aristulate; awn geniculate with twisted column or merely outwardly curved; palea hyaline, slightly to distinctly shorter than lemma, gaping free from lemma margins. Ovary glabrous or almost so. Caryopsis with punctiform hilum; endosperm sometimes liquid.[1] [more]
At least 324 species and subspecies belong to the Genus Trisetum.
