Small, delicate grey-green or blue-green, rarely reddish perennial, forming intravaginal tufts 5- 40 cm tall, with a few extravaginal shoots at plant base; leaves usually much shorter than culms, densely packed, wiry, short and curved, or longer and erect; laminae persistent. Sheaths very pale brown, often purplish, membranous, distinctly nerved, minutely scabrous abaxially, occasionally smooth; ligule 0.2-0.7 mm long, truncate, erose, abaxially smooth; lamina 0.5-1.5-(5) cm × 1-1.5- (3) mm, usually fine and folded, adaxially with minute scattered teeth, abaxially smooth, but midnerve scabrous near boat-shaped tip, margins inrolled, sparingly scabrous. Culms (1.5)—5—15— (40) cm tall, very slender, purplish, smooth, usually bearing 2 small cauline leaves. Panicle 1.5-6.5- (8) cm long, open; rachis glabrous, branchlets capillary, sometimes flexuous, very minutely scabrous with teeth scarcely visible except at high magnification, with rather few spikelets, clustered 2-3 at branchlet tips. Spikelets 1.5-4.5 mm long, (1)-3- 5-(6)-flowered, silvery purple-green. Glumes subequal, 1-2 mm long, with wide hyaline margins, midnerve slightly scabrous in upper ½ or near tip; lower glume narrower, ovate-lanceolate, acute, 1- (3)-nerved, upper ovate, obtuse, 3-nerved, sometimes with a few teeth on margins and on lateral nerves above. Lemma 1-2 mm long, 5-nerved, ovate, obtuse, covered almost throughout or for about 2/3 length with long, appressed, silky hairs, c. 0.2 mm long, midnerve scabrous and internerves glabrous near membranous tip. Palea 1-2 mm long, long appressed-ciliate between long-ciliate keels, some hairs on margins. Lodicules 0.2-0.4 mm long. Callus glabrous. Rachilla to 0.5 mm long, with scattered long hairs or almost glabrous. Anthers 0.2- 0.5 mm long. Caryopsis c. 1 × 0.5 mm. 2n = 28. Endemic

Small, delicate grey-green or blue-green, rarely reddish perennial tufts, 5-40 cm, with densely packed wiry, short and curved, or longer and erect leaves usually « culms; branching intravaginal, with a few extravaginal shoots at plant base; leaf-blades persistent. Leaf-sheath very pale brown, often purplish, membranous, distinctly ribbed, minutely scabrid abaxially, occasionally smooth. Ligule 0.2-0.7 mm, truncate, erose, glabrous throughout. Leaf-blade 0.5-1.5-(5) cm × 1-1.5-(3) mm, usually fine and folded, adaxially with minute scattered prickle-teeth, abaxially smooth, but midrib scabrid near naviculate tip; margins inrolled, sparingly scabrid. Culm (1.5)-5-15-(40) cm, very slender, purplish, usually bearing 2 small cauline leaves, internodes glabrous.
