Caucasian Bluestem Grass is a clustered perennial grass with stems 50-150 cm high, erect from a shortly rhizomatous base, often robust. Leaves are long and narrow, 10-55 cm long, 2-12 mm wide. Flowers are borne in a cluster with a central axis 4-20 cm long, the racemes numerous and borne loosely or densely in irregular whorls upon simple or branched flower-cluster-stalks. Racemes are 2-5 cm long (the lowest shorter than the central axis), velvet-hairy. Stalkless spikelet are narrowly elliptic, 3-4 mm long; lower glume papery, hairy below the middle, usually not glossy, with or without a pit; awn 10-25 mm long. Stalked spikelets are hairless, barren or rarely staminate, narrower than stalkless spikelet, sometimes pitted. Caucasian Bluestem Grass is widespread in tropical and temperate Asia, tropical Africa and Australia. It is found in the Himalayas at altitudes of 400-1600 m.
