Perennial. Innovations intravaginal. Culms about 30 cm tall, erect, terete, scabrous, with two nodes; the upper node situated about the middle of the culm; leafy up to the apex. Sheaths shorter than the internodes, terete; the lower ones tight, the uppermost dilated; all scabrous downward; when withered becoming brownish, opaque. Ligules lanceolate, somewhat acute, 2–3 mm long. Blades all setaceously convolute, very acute, rigid; the lower ones equaling or surpassing half the culm; those of the innovations 10–15 cm long, 0.5 mm in diameter; those of the culm shorter; all very scabrous beneath, grayish-green.
Panicle linear, contracted, sheathed at the base or shortly exserted from the sheath, 10–12 cm long; lower branches paired, upper solitary; all short, erect, scabrous; mostly bearing one spikelet, the lowest sometimes two; spikelet pedicels appressed to the rachis, the lower ones slightly longer than the spikelets, the upper ones several times shorter. Spikelets lanceolate, 3 cm long, greenish.
Sterile glumes lanceolate, 12–14 mm long, herbaceous-membranous in the lower part, hyaline-setaceous in the upper, produced into a very slender point; 3-nerved; glabrous or scabrous above along the midnerve. Fertile glume linear-oblong, about 10 mm long; callus pungent, densely bearded with fulvous hairs 2 mm long; otherwise marked with five silky-pilose lines, of which two marginal lines extend to ¾ of the glume, the remaining three to ½; the rest of the back minutely punctulate-scaberulous; apex glabrous; awn exserted, 8–10 cm long; column 2–2.5 cm long, glabrous or scarcely scaberulous, geniculate above the middle, with a distinct geniculation separating it from the seta; seta plumose, three to four times longer than the column, briefly naked at the very tip. Palea equaling the glume, linear-oblong, obtuse, somewhat tubular, 2-nerved, glabrous. Lodicules 2 mm long. Anthers 6 mm long, usually exserted, rarely during anthesis retained within the glume and palea.

Very closely related to Stipa pennata L., but at first glance already distinct by its awns, which are two to three times shorter (8–10 cm, whereas in Stipa pennata they are 20–35 cm long). Furthermore, it differs from all by the sheaths being strongly scabrous downward, and from most subspecies of Stipa pennata (except Stipa tirsa) by its very scabrous leaf blades. From Stipa tirsa it is further distinguished by its lanceolate ligule, 2–3 mm long.
