Eriachne glabrata

HABIT Perennial; caespitose. Culms 15–30 cm long; 2–5 -noded. Culm-internodes distally woolly. Ligule a fringe of hairs. Leaf-blades erect; involute; 2–4(–8) cm long; 1–2 mm wide; stiff.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 2–4 cm long. Primary panicle branches simple; bearing spikelets almost to the base. Panicle branches scaberulous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets cuneate; laterally compressed; compressed slightly; 3–4 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent.

GLUMES Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma; gaping. Lower glume ovate; 2.5–3.5 mm long; 1 length of upper glume; membranous; without keels; 7–9 -veined. Lower glume apex obtuse. Upper glume ovate; 2.5–3.5 mm long; 0.8–0.9 length of adjacent fertile lemma; membranous; without keels; 5–7 -veined. Upper glume apex obtuse.

FLORETS Fertile lemma ovate; laterally compressed; 3–4 mm long; chartaceous; without keel; 5–7 -veined. Lemma surface pubescent. Lemma margins involute; interlocking with palea keels. Lemma apex acute; muticous. Palea 1 length of lemma; chartaceous; 2 -veined. Palea surface pubescent; hairy on back.
