Perennial; tufts small, 5-15 cm tall, narrow, glaucous; new shoots extravaginal at plant base, intravaginal above; laminae persistent. Sheaths shining, greenish or reddish-purple, later light greybrown, membranous, smooth, veins conspicuous; ligule 0.2-0.7 mm long, entire, smooth across top, rounded or sometimes narrowed to a point at centre, abaxially minutely papillose; lamina 1-6- (9) cm × 0.6-2 mm, usually folded, with inrolled shortly scabrous margins, abaxially smooth except on midnerve near curved tip, adaxially smooth and glabrous but shortly hairy above ligule and occasionally with a few teeth along midnerve, veins indistinct. Culms 2-9-(16)cm tall, often closely short-scabrous below panicle or smooth. Panicle 0.5-2.5 cm long, compact, spike-like or racemose, very rarely more open with few, very short branchlets; rachis and minute, stiff, angled ± densely short-scabrous branchlets with few spikelets on scabrous pedicels. Spikelets 2.5-3.5 mm long, 2-3- (4)-flowered, light green tinged purple. Glumes subequal, usually 1.5-2.5 mm long, smooth, with a few teeth on nerves in upper half; lower glume occasionally smaller, 1-1.5 mm long, 1-(3)-nerved, narrow- to ovate-elliptic, subobtuse to obtuse, upper 3-nerved, ovate, obtuse. Lemma c. 2-2.5 mm long, 5-(7)-nerved, ovate, strongly folded about midnerve, obtuse, sometimes almost hooded, midnerve scabrous towards tip, elsewhere surface minutely papillose, occasionally minutely scabrous near distinct membranous margin. Palea 1.5- 2.3 mm long, scabrous on upper ½ of keels, elsewhere smooth. Lodicules 0.4-0.5 mm long. Callus glabrous. Rachilla c. 0.5 mm long, smooth and glabrous, projection usually twice as long. Anthers 0.2- 0.5 mm long. Caryopsis 1-1.3 × c. 0.5 mm. Endemic

Small perennial tufts, 5-15 cm, narrow, glaucous; branching extravaginal at plant base, intravaginal above; leaf-blades persistent. Leaf-sheath shining, greenish or reddish purple, later light grey-brown, membranous, glabrous, ribs conspicuous. Ligule 0.2-0.7 mm, apically glabrous, entire, rounded or sometimes centrally narrowed to a point, abaxially minutely papillose. Leaf-blade 1-6-(9) cm × 0.6-2 mm, usually folded, abaxially smooth, but scabrid on midrib near curved tip, adaxially glabrous, but shortly hairy above ligule and occasionally with a few prickle-teeth on midrib, lateral ribs indistinct; margins inrolled, shortly prickle-toothed. Culm 2-9-(16) cm, internodes often closely short-scabrid below panicle or smooth. Panicle 0.5-2.5-(3) cm, compact, spike-like or racemose, very rarely more open with few, very short branches; rachis and branches stiff, angular, ± densely scabrid, spikelets few on scabrid pedicels. Spikelets 2.5-3.5 mm, 2-3-(4)-flowered, light green tinged purple. Glumes subequal, usually 1.5-2.5 mm, glabrous, with a few prickle-teeth on nerves in upper ½; lower occasionally smaller, 1-1.5 mm, 1-(3)-nerved, narrow- to ovate-elliptic, subobtuse to obtuse, upper 3-nerved, ovate, obtuse. Lemma c. 2-2.5 mm, 5-(7)-nerved, ovate, strongly folded about midnerve, obtuse, sometimes almost hooded, minutely papillose or occasionally minutely scabrid near distinct membranous margin, midnerve scabrid towards tip. Palea 1.5-2.3 mm, keels scabrid on upper ½, interkeel and flanks glabrous. Callus glabrous. Rachilla c. 0.5 mm, glabrous; prolongation usually twice as long. Lodicules 0.4-0.5 mm. Anthers 0.2-0.5 mm. Gynoecium: ovary 0.4-0.5 mm; stigma-styles 0.75-1.1 mm. Caryopsis 1-1.3 ×c. 0.5 mm.
