Isachne multiflora

HABIT Perennial. Culms erect; 30–90 cm long. Culm-nodes glabrous. Leaf-sheaths glabrous on surface; outer margin hairy. Ligule a fringe of hairs. Leaf-blades linear; 5–15 cm long; 3–8 mm wide. Leaf-blade surface scaberulous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; ovate; 6–21 cm long. Primary panicle branches ascending.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 1.9–2.1 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes deciduous; similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 1.2–1.7 mm long; 1 length of spikelet; membranous; without keels; 7–9 -veined. Lower glume apex obtuse. Upper glume ovate; 1.1–1.6 mm long; 1 length of spikelet; membranous; without keels; 7–9 -veined. Upper glume apex obtuse.

FLORETS Fertile florets with the lowest dissimilar. Lowest fertile lemma elliptic; 1.9–2.4 mm long; 2 length of adjacent lemma; thinner than adjacent lemma. Fertile lemma orbicular; 1.1–1.3 mm long; coriaceous; without keel. Lemma surface puberulous. Lemma margins involute. Lemma apex obtuse. Palea coriaceous; 2 -veined.

FLOWER Anthers 3; 1.3 mm long.
