Arrhenantherum, commonly called Oat 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)
Oat-grass is a very common perennial with yellowish roots. The shining stems grow to a height of 1.50 m, but die off in winter. The leaves are hairless with blunt ligules. The inflorescence spreads into a panicle with 2-flowered bisexual spikelets.
