Arrhenatherum, commonly called oatgrass or button-grass, is a genus of Eurasian and North African plants in the grass family.[4][5][6][7]
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.[8]
