Rytidosperma tenue (Petrie) Connor & Edgar
Slender tufts, often with tufts of leaves at ends of elongating shoots, rooting at nodes; leaves < culms; new shoots extra- and intravaginal. Sheaths light brown, usually with scattered long hairs, sometimes glabrous; collar hairs to 2 mm long; ligule 0.2-0.3 mm long; lamina to 15 cm long, inrolled, mostly glabrous but margins slightly scabrous near base. Culms up to 25 cm long, glabrous, finely scabrous below inflorescence. Panicle erect, contracted, narrow, 1-7 cm long, of few spikelets on short pedicels; rhachis and pedicels uniformly closely short-scabrous; spikelets 4-5-(6)-flowered, awns ± included by glumes. Glumes purpled centrally, lanceolate, subacute, 6-7.4 mm long, ± equal, both 5-nerved. Lemma c. 2 mm long, 9- nerved, upper row of hairs dense, continuous, = or > lemma lobes, lower row ± indistinct except for marginal tufts, elsewhere with short scattered hairs; lemma lobes 0.7-1.2 mm long, tapering to minute awn or membranous. Central awn 1.5-2.5 mm long; column c. 0.5 mm long, sometimes not developed, < palea and upper lemma hairs. Palea c. 2.5 mm long, < or almost = upper lemma hairs, glabrous between keels, margins with a few long hairs. Callus 0.2- 0.3 mm long with very short marginal hair tufts not, or a few just reaching lower row of lemma hairs. Rhachilla c. 0.7-1 mm long. Anthers 0.6-0.9 mm long. Caryopsis not seen. Endemic.
