Characteristics

Slender tufts, often with tufts of leaves at ends of elongating shoots, rooting at nodes; leaves < culms; branching extra-and intravaginal. Leaf-sheath light brown, usually with scattered long hairs, sometimes smooth; apical tuft of hairs to 2 mm. Ligule 0.2-0.3 mm. Leaf-blade to 15 cm, inrolled, mostly glabrous but margins slightly scabrid near base. Culm to 25 cm, internodes smooth but finely scabrid below inflorescence. Panicle erect, contracted, narrow, 1-7 cm, of few spikelets on short pedicels; rachis and pedicels uniformly closely short-scabrid. Spikelets 4-5-(6)-flowered, awns ± included by glumes. Glumes purplish centrally, lanceolate, subacute, 6-7.4 mm, ± equal, 5-nerved. Lemma c. 2 mm, 9-nerved, upper row of hairs dense, continuous, ≥ lemma lobes, lower row ± indistinct except for marginal tufts, elsewhere short scattered hairs; lobes 0.7-1.2 mm, tapering to minute awn or membranous; central awn 1.5-2.5 mm, column c. 0.5 mm, sometimes absent, < palea and upper lemma hairs. Palea c. 2.5 mm, ≤ upper lemma hairs, interkeel glabrous, margins with a few long hairs. Callus 0.2-0.3 mm, very short marginal hair tufts not, or a few just reaching lower row of lemma hairs.
