Glumes indurated, lower glume if present a reduced bract, upper glume 4-6-(7) mm, minutely hairy above and on margins, ± golden ochreous often tinged pinkish at first, nerves 7 very weak; awn 0.5-2-(5) mm, scabrid. Lemma 3-3.75 mm, ovate-lanceolate, 1-nerved, firm-hyaline, glabrous. Palea 2.75-3.5 mm, transparent. Anthers c. 2-2.6 mm, apiculate, filaments ligulate.

Plant perennial with extensive wiry rhizomes. Rhizomes mostly in series of three internodes — 2 very short and 1 long — the three internodes 1-3 cm long. The longer internode subtended by longer cataphyll. Cataphylls rounded to truncate, lingulate, more or less distinctly umbonate. Erect culms arise from short internodes, 4-10 cm high above ground, branching several times at and above ground. Branching intravaginal; 2-3 internodes elongated, uppermost mostly 2-5 cm long. Leaf sheath 1-3 cm long, glabrous, finely striated. Ligule 0.2-0.5 mm long, ciliar. Leaf collar distinct, more or less ciliate with long soft cushionbased hairs. Blade up to 7 cm long, more or less flat 1-1.5 mm wide, tapering, more or less finely striate on both sides, glabrous. Vascular bundles mostly about 15. Sclerenchyma bilateral, interrupted between vascular bundles, connected with primary bundles, more or less free from secondary bundles. Peduncle 2-5 cm long, glabrous. Racemes 7-12 mm long of 3-5 spikelets. Rachis and pedicels minutely scabrid. Pedicels 0.5-1 mm long, spikelets about 4 mm long, lanceolate. Glume 4 mm long, ± ovate, indurated with thin margins minutely hairy above and on margins, more or less golden ochreous, about 7-nerved, nerves weak, awn 0-5 mm long. Lemma about 3.5 mm long ovate-lanceolate, glabrous. Anthers about 2 mm long. Stigmas long, plumose (Fig. 1).

Plant perennial. Rhizome internodes mostly in series of three — 2 very short and 1 long — the three internodes 1-2 cm long. Cataphylls truncate, lingulate, almost quite bladeless. Erect culms arise from one or both short internodes, 8-15 cm high above ground, branching several times at and above ground. Branching intravaginal; 2-3 internodes elongated, uppermost 4-7 cm long. Leaf sheath 1-3 cm long, glabrous finely striated. Ligule a line of hairs 0.3-0.5 mm long. Leaf collar distinct, more or less densely long-ciliate, hairs soft, cushion-based. Blade more or less distinctly divergent rolled in bud, flat at maturity, up to 5 cm long 2-3 mm wide, tapering, finely striate on both sides, glabrous. Vascular bundles about 25. Sclerenchyma bilateral, interrupted between vascular bundles, connected with primary bundles, more or less free from secondary bundles. Peduncle 4-7 cm long, glabrous. Racemes 8-16 mm long, of 6-12 appressed spikelets. Rachis and pedicels minutely scabrid. Pedicels 0.5-1 mm long. Spikelets about 4 mm long, lanceolate. Glume 4 mm long, ovate, indurated with thin margins, minutely hairy above and on margins, stramineous, about 7-nerved, nerves very weak. Lemma about 3.5 mm long, ovate-lanceolate, more or less conduplicate, 1-nerved, firm, hyaline, glabrous. Anthers about 2 mm long. Stigmas long, plumose (Fig. 1).
