Entolasia stricta
HABIT Perennial; caespitose. Rhizomes short. Butt sheaths pilose. Culms geniculately ascending, or decumbent, or rambling; 20–80(–120) cm long; wiry; 4–10 -noded; without nodal roots, or rooting from lower nodes. Culm-internodes scaberulous; distally glabrous, or hirsute; with tubercle-based hairs. Ligule a fringe of hairs. Leaf-blades deciduous at the ligule; involute; 0.5–10 cm long; 1–7 mm wide; stiff. Leaf-blade midrib indistinct. Leaf-blade surface scaberulous; glabrous, or hirsute; with tubercle-based hairs. Leaf-blade margins cartilaginous. Leaf-blade apex attenuate; hardened.
INFLORESCENCE Inflorescence composed of racemes.
Racemes 2–9; borne along a central axis; erect; unilateral; 2–7 cm long; bearing 2–10 fertile spikelets on each (secondary); simple, or secondarily branched. Central inflorescence axis 2–10 cm long. Rhachis angular; scaberulous on margins. Spikelet packing adaxial; regular; 2 -rowed.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels linear; flattened; 0.5–1.5 mm long.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; obtuse, or subacute; 2.25–3.5 mm long; falling entire.
GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.75–1 mm long; 0.25–0.33 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute, or acuminate. Upper glume elliptic; 2.25–3.5 mm long; 1 length of adjacent fertile lemma; 1 length of spikelet; herbaceous; without keels; 5 -veined. Upper glume surface smooth, or asperulous; rough on veins. Upper glume apex acute.
FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 2.25–3.5 mm long; 1 length of spikelet; herbaceous; 5 -veined; smooth, or scaberulous; rough on veins; acute. Fertile lemma elliptic; dorsally compressed; 2.25–3.5 mm long; coriaceous; without keel; 5 -veined. Lemma lateral veins obscure. Lemma surface pubescent; hairy all along. Lemma margins involute. Lemma apex obtuse, or acute. Palea involute; coriaceous; 2 -veined. Palea surface pubescent.
DISTRIBUTION Asia-tropical: Papuasia. Australasia: Australia.
NOTES Paniceae. Vickery.
