Rytidosperma setifolium (Hook.f.) Connor & Edgar

Stiff, yellow-green or bright green tussocks, often with tufts of leaves at ends of elongating shoots, rooting at nodes; leaves semi-pungent, ± =, or < culms (occasionally very much shorter), disarticulating at ligule; new shoots intravaginal. Sheaths pale stramineous, glabrous; collar hairs (0.2)—1.0-3.0 mm long; ligule 0.2-0.8 mm long; lamina to 25-(35) cm long, stiff, inrolled, rounded, glabrous, margins glabrous. Culms up to 50 cm tall, glabrous. Panicle ± erect, to 6 cm long, of few large spikelets on very slender pedicels; rhachis and pedicels almost glabrous or with a few scattered prickle-teeth usually along edges and below spikelets, a few long hairs at branch axils. Spikelets (3)-4-6-flowered, awns exserted from glumes. Glumes becoming light redpurple to purple-black centrally, lanceolate, subobtuse to acute, (5.5)—7—11—(20) mm long, ± equal, lower 3-5-nerved, upper (3)-5-(7)-nerved. Lemma (2)-2.5-3.5-(4) mm long, 7-9-nerved, upper and lower rows of hairs continuous, upper row slightly < lemma lobes, lower row usually reaching to base of upper row, glabrous elsewhere but occasional hairs centrally, margins often hair-fringed; lemma lobes (2.3)-3-4—(5) mm long, tapering to short fine awn. Central awn 8-12 mm long, widely divergent; column 1-2 mm long, usually < upper lemma hairs. Palea 3-5 mm long, = or > upper lemma hairs, glabrous between keels or occasionally with scattered short hair, margins with long hairs on lower half or glabrous. Callus c. 0.5 mm long with short marginal hair tufts overlapping lower lemma hairs. Rhachilla 0.6-1 mm long, occasionally crowned with minute hairs. Anthers (1.2)— 1.5—3 mm long. Caryopsis 1.1- 1.5 × 0.6-0.7 mm; embryo 0.5-0.8 mm long; hilum 0.2-0.3 mm long. Endemic.

Rytidosperma setifolium (Hook.f.) Connor & Edgar

Stiff, yellow-green or bright green tussocks, often with tufts of leaves at ends of elongating shoots, rooting at nodes; leaves semi-pungent, ≤ culms (occasionally very much shorter), disarticulating at ligule; branching intravaginal. Leaf-sheath pale stramineous, glabrous; apical tuft of hairs (0.2)-1.0-3.0 mm. Ligule 0.2-0.8 mm. Leaf-blade to 25-(35) cm, stiff, inrolled, rounded, glabrous, margins glabrous. Culm to 50 cm, internodes glabrous. Panicle ± erect, to 6 cm, of few large spikelets on very slender pedicels; rachis and pedicels almost glabrous or with a few scattered prickle-teeth usually along edges and below spikelets, a few long hairs at branch axils. Spikelets (3)-4-6-flowered, awns exserted from glumes. Glumes becoming light red-purple to purple-black centrally, lanceolate, subobtuse to acute, (5.5)-7-11-(20) mm, ± equal; lower 3-5-nerved, upper (3)-5-(7)-nerved. Lemma (2)-2.5-3.5-(4) mm, 7-9-nerved, upper and lower rows of hairs continuous, upper row slightly &lt; lemma lobes, lower row usually reaching to base of upper row, glabrous elsewhere but occasional hairs centrally, margins often hair-fringed; lobes (2.3)-3-4-(5) mm, tapering to short fine awn; central awn 8-12 mm, widely divergent, column 1-2 mm usually &lt; upper lemma hairs. Palea 3-5 mm, ≥ upper lemma hairs, interkeel glabrous or occasional scattered short hairs, margins with long hairs below or glabrous. Callus c. 0.5 mm, short marginal hair tufts overlapping lower lemma hairs. Rachilla 0.6-1 mm, occasionally crowned with minute hairs. Anthers (1.2)-1.5-3 mm. Caryopsis 1.1-1.5 × 0.6-0.7 mm; embryo 0.5-0.8 mm; hilum 0.2-0.3 mm. 2n= 24. Plates 6A, 11E.
