Pseudarrhenatherum
''Arrhenatherum'', commonly called oatgrass or button-grass, is a genus of Eurasian and North African plants in the grass family. Description Wild forms can resemble wild oat (''Avena'') or fescue (''Festuca''). Oatgrasses are very common perennials with yellowish roots. The shining stems grow to a height of 1.5 meters, but die off in winter. The leaves are hairless with blunt ligules. The inflorescence is a panicle with two-flowered bisexual spikelets. ; Species * ''Arrhenatherum album'' - tall oatgrass - Mediterranean from Portugal to Cyprus * ''Arrhenatherum calderae'' - Tenerife in Canary Islands * ''Arrhenatherum elatius'' - false oatgrass, tall oatgrass, tall meadow oat - Eurasia + North Africa from Iceland to Canary Islands + Kazakhstan; naturalized in East Asia, Australia, New Zealand, the AmericasRosengurtt, B., B.

List Of Poaceae Genera
The true grasses ( Poaceae) are one of the largest plant families, with around 12,000 species and roughly 800 genera. They contain, among others, the cereal crop species and other plants of economic importance, such as the bamboos, and several important weeds. Grasses probably originated in the understory of tropical rainforests in the Late Cretaceous, but have since come to occupy a wide range of different habitats. Notably, they are the dominant species in grasslands, open habitats that cover around one fifth of the earth's terrestrial surface. The C4 photosynthetic pathway has evolved at least 22 times independently in the grasses; C4 species are more competitive than C3 plants in open habitats with high light intensity and warm temperatures. The deeper relationships in the family have been resolved by recent molecular phylogenetic work. This has been translated into a modern classification which divides the grasses into twelve subfamilies and a number of tribes, with ...

Arrhenatherum Elatius
''Arrhenatherum elatius'', with the common names bulbous oat grass, false oat-grass, tall oat-grass, tall meadow oat, onion couch and tuber oat-grass, is a species of perennial grass, native to Europe, western Asia, and northern Africa. This bunchgrass is often used as an ornamental grass and is sometimes marketed as " cat grass". It is native to Europe but can be found elsewhere as an introduced species. It is found especially in prairies, at the side of roads and in uncultivated fields. The bulbous subspecies can be a weed of arable land. It is palatable grass for livestock and is used both as forage (pasture) and fodder (hay and silage). Description This coarse grass can grow to tall. The leaves are bright green, broad, slightly hairy, and rough. The ligule is long and smooth edged. The panicle is up to , and the bunched spikelets have projecting and angled awns up to long, green or purplish. The panicles often remain into winter. The spikelets are oblong or gaping. I ...

Panicle
A panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses such as oat and crabgrass, as well as other plants such as pistachio and mamoncillo. Botanists use the term paniculate in two ways: "having a true panicle inflorescence" as well as "having an inflorescence with the form but not necessarily the structure of a panicle". Corymb A corymb may have a paniculate branching structure, with the lower flowers having longer pedicels than the upper, thus giving a flattish top superficially resembling an umbel. Many species in the subfamily Amygdaloideae, such as hawthorns and rowans, produce their flowers in corymbs. up'' Sorbus glabrescens'' corymb with fruit See ...
