Small, finely rhizomatous tufts 3-5-(20) cm, with fine, pale green or blue-green, to light brown leaves, and narrowly branched, delicate panicles usually scarcely overtopping leaves; branching extravaginal at base, intravaginal above. Leaf-sheath ± hyaline, light green to light brown, glabrous, ribs few, prominent. Ligule 0.1-0.6 mm, truncate, minutely ciliate or erose, abaxially glabrous. Leaf-blade 0.8-2.5 cm × 0.2-0.4 mm diam., narrow-linear, involute, filiform, abaxially smooth except near blunt, minutely scabrid tip, adaxially usually finely scabrid on ribs. Culm slender, erect, internodes glabrous. Panicle 0.6-2-(3) cm, open, ovate to pyramidal, with few, minutely, sparsely ciliate branches each tipped by a single spikelet. Spikelets (1.2)-1.5-2 mm, pale green to light creamy brown, sometimes purplish. Glumes ± equal, and usually ≈ lemma, ovate-lanceolate, subobtuse, keel scabrid near tip, margins sometimes finely ciliate near tip. Lemma 1.2-1.8 mm, glabrous, faintly 5-nerved, ovate, obtuse or almost truncate, awnless. Palea 0.4-0.6 mm, ovate. Lodicules 0.2-0.4 mm. Callus glabrous. Anthers 0.4-0.7-(1) mm. Caryopsis c. 1 × 0.5 mm.

Small, finely rhizomatous tufts 3-5-{20) cm tall, with fine, pale green or blue-green, to light brown leaves and narrowly branched, delicate panicles usually scarcely overtopping leaves; branching extravaginal at plant base, intravaginal above. Sheaths ± hyaline, light green to light brown, smooth, with few, well-marked nerves; ligule 0.1-0.6 mm, truncate, minutely ciliate across top or erase, abaxially smooth; lamina 0.8-2.5 cm × 0.2-0.4 mm, narrow-linear, involute, filiform, abaxially glabrous except near blunt, minutely scabrous tip, adaxially usually finely scabrous along nerves. Culms slender, erect, smooth. Panicle 0.6-2-(3) cm long, open, ovate to pyramidal, with few, minutely, sparsely ciliate branchlets each tipped by a single spikelet. Spikelets (1.2)—1.5-2 mm, pale green to light creamy brown, sometimes purplish. Glumes ± equal, and usually c. = lemma, ovatelanceolate, subobtuse, scabrous on keel near tip and sometimes finely ciliate on margins near tip. Lemma 1.2-1.8 mm, smooth, glabrous, faintly 5-nerved, ovate, obtuse or almost truncate, awnless. Palea 0.4-0.6 mm, ovate. Lodicules 0.2-0.4 mm. Callus glabrous. Anthers 0.4-0.7-(l) mm. Caryopsis c. 1 × 0.5 mm. Endemic.
