Arrhenatherum Explained
Arrhenatherum, commonly called oat-grass or button-grass, is a genus of Eurasian and North African plants in the grass family.[1] [2] [3] [4]
Description
Wild forms can resemble wild oat (Avena) or fescue (Festuca). Oat-grasses are very common perennials with yellowish roots. The shining stems grow to a height of 1.8abbr=onNaNabbr=on,[5] but die off in winter. The leaves are hairless with blunt ligules. The inflorescence is a panicle with two-flowered bisexual spikelets.[6]
