Rytidosperma nudum (Hook.f.) Connor & Edgar

Open small tufts, leafy at ends of elongating shoots, rooting at nodes; leaves somewhat acute, ± = culms, disarticulating at ligule; new shoots intravaginal. Sheaths pale stramineous to light grey, glabrous; collar hairs few, up to 1-2 mm long; ligule to 0.4 mm long; lamina to 8 cm long, folded, narrow, rather soft, glabrous. Culms up to 10 cm tall, glabrous. Panicle small, erect, up to 3 cm long; with few spikelets on short pedicels; rhachis and pedicels slender, closely short-scabrous with some longer hairs at branch axils. Spikelets usually 3-flowered, awns barely exserted from glumes. Glumes purpled centrally, ovate, obtuse, ± equal, 3.5—5—(5.7) mm long, lower 3-(5)-nerved, upper 3-nerved. Lemma 2.3-3.5 mm long, 5-(9)-nerved, upper and lower rows of hairs very sparse, upper row usually of small marginal tufts with a few scattered hairs between, < lemma lobes, lower row of small marginal tufts and few scattered hairs, elsewhere glabrous, margins with scattered hairs; lemma lobes 0.2-0.5 mm long, acute to acuminate, not awn-tipped. Central awn 1-2 mm long, erect; column scarcely developed. Palea 2.4-2.8 mm long, reaching base of awn-sinus, = upper lemma hairs, glabrous between keels, margins occasionally with a few long hairs. Callus c. 0.3 mm long, with a few marginal hairs not reaching lower lemma hairs, or marginal tufts denser, slightly overlapping lower lemma tufts. Rhachilla 0.5- 0.8 mm long. Anthers 0.7-0.8 mm long. Caryopsis not seen. Endemic.

Rytidosperma nudum (Hook.f.) Connor & Edgar

Open small tufts, leafy at ends of elongating shoots, rooting at nodes; leaves somewhat acute, ≈ culms, disarticulating at ligule; branching intravaginal. Leaf-sheath pale stramineous to light grey, glabrous; apical tuft of hairs few, up to 1-2 mm. Ligule to 0.4 mm. Leaf-blade to 8 cm, folded, narrow, rather soft, glabrous. Culm to 10 cm, internodes glabrous. Panicle small, erect, to 3 cm, of few spikelets on short pedicels; rachis and pedicels slender, closely short-scabrid and some longer hairs at branch axils. Spikelets usually 3-flowered, awns barely exserted from glumes. Glumes purplish centrally, ovate, obtuse, ± equal, 3.5-5-(5.7) mm; lower 3-(5)-nerved, upper 3-nerved. Lemma 2.3-3.5 mm, 5-(9)-nerved, upper and lower rows of hairs very sparse, upper row usually of small marginal tufts with a few scattered hairs between, &lt; lemma lobes, lower row of small marginal tufts and few scattered hairs, elsewhere glabrous, margins with scattered hairs; lobes 0.2-0.5 mm, acute to acuminate, not awn-tipped; central awn 1-2 mm, erect, column scarcely developed. Palea 2.4-2.8 mm, reaching base of awn sinus, = upper lemma hairs, interkeel glabrous, margins occasionally with a few long hairs. Callus c. 0.3 mm, a few marginal hairs not reaching lower lemma hairs, or marginal tufts denser, slightly overlapping lower lemma tufts. Rachilla 0.5-0.8 mm. Anthers 0.7-0.8 mm. Caryopsis not seen. Plate 12E.
