Sacciolepis fenestrata

HABIT Annual. Culms erect, or geniculately ascending; 20–35 cm long. Culm-nodes glabrous. Ligule an eciliate membrane; 1 mm long. Leaf-blades 3–7 cm long; 1–2 mm wide. Leaf-blade surface glabrous. Leaf-blade margins smooth. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle spiciform; linear, or oblong; 2–3.5 cm long. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1.5–1.75 mm long.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; gibbous; 1.7 mm long; falling entire.

GLUMES Glumes reaching apex of florets; thinner than fertile lemma. Lower glume orbicular; 0.75 mm long; 0.5 length of spikelet; hyaline; without keels; 3 -veined. Lower glume apex obtuse. Upper glume ovate; gibbous; 1.7 mm long; 2 length of adjacent fertile lemma; 1 length of spikelet; chartaceous; much thinner above; without keels; 7 -veined. Upper glume lateral veins ribbed. Upper glume surface pubescent; hairy between veins; with tubercle-based hairs. Upper glume apex acute.

FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; gibbous; 1 length of spikelet; chartaceous; much thinner above; fenestrate; 5–7 -veined; ribbed; pilose; hairy between veins; with tubercle-based hairs; acute. Fertile lemma elliptic; dorsally compressed; 0.9–1 mm long; chartaceous; shiny; without keel. Lemma margins involute. Lemma apex acute. Palea involute; chartaceous.

FLOWER Anthers 3; 0.3 mm long.

DISTRIBUTION Asia-tropical: Indo-China.
