Bromus

Bromus is a large genus of grasses, classified in its own tribe Bromeae. They are commonly known as bromes, brome grasses, cheat grasses or chess grasses. Estimates in the scientific literature of the number of species have ranged from 100 to 400, but plant taxonomists currently recognize around 160–170 species.

Bromus is part of the cool-season grass lineage (subfamily Pooideae), which includes about 3300 species. Within Pooideae, Bromus is classified in tribe Bromeae (it is the only genus in the tribe). Bromus is closely related to the wheat-grass lineage (tribe Triticeae) that includes such economically important genera as Triticum (wheat), Hordeum (barley) and Secale (rye).

The generic name Bromus is derived from the Latin bromos, a borrowed word from the Ancient Greek βρομός. βρομός and bromos mean oats, but βρομός seems to have referred specifically to Avena sativa (Hp.Vict.2.43, Dsc.2.94, Polem.Hist.88) and Avena barbata (Thphr.HP8.9.2, Ps.-Dsc.4.137). The generic name Avena is another Latin word for oats or wild oats.
