    Habit
    Annual. Culms slender; 30-65 cm long. Ligule a ciliate membrane. Leaf-blades parallel-sided; 8-14 cm long; 3-9 mm wide; membranous. Leaf-blade surface glabrous. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle. Panicle open; oblong, or ovate; 14-18 cm long; contracted about primary branches. Primary panicle branches spreading, or reflexed. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acute; 2.2-2.5 mm long; falling entire.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; acute; 2.2-2.5 mm long; falling entire.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume oblate; 0.25-0.33 length of spikelet; membranous; without keels; 5 -veined. Lower glume apex acute. Upper glume ovate; 1 length of spikelet; membranous; without keels; 9 -veined. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 9 -veined; acute. Fertile lemma oblong; dorsally compressed; 2 mm long; indurate; pallid; shiny; without keel. Lemma margins involute. Lemma apex obtuse. Palea involute; indurate.
