Echinochloa jubata Stapf

[GB]
Morphology General Habit
Perennial. Culms geniculately ascending, or rambling; 50-200 cm long; spongy. Culm-nodes glabrous. Leaf-sheaths glabrous on surface, or pubescent. Ligule a fringe of hairs. Leaf-blades 10-25 cm long; 3-15 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes borne along a central axis; closely spaced; in a multilateral false spike; unilateral; 2-4 cm long; simple. Central inflorescence axis 8-20 cm long. Rhachis angular. Spikelet packing crowded; irregular; 4 -rowed. Spikelets in pairs. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; gibbous; acuminate; 3-3.5(-4) mm long; falling entire.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; gibbous; acuminate; 3-3.5(-4) mm long; falling entire.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.25-0.75 length of spikelet; membranous; without keels; 3-5 -veined. Lower glume surface hispidulous. Lower glume apex cuspidate. Upper glume ovate; membranous; without keels; 5-7 -veined. Upper glume surface hispidulous. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 1-6 mm long.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 7 -veined; hispidulous; acuminate; awned. Awn of lower sterile floret 3-25 mm long. Fertile lemma ovate; gibbous; 2.5-3 mm long; indurate; much thinner above; shiny; without keel; 5 -veined. Lemma margins involute. Lemma apex acute; laterally pinched. Palea reflexed at apex; indurate.

Morphology General Habit
Perennial; culms soft, 50–200 cm. high, rambling or ascending; nodes glabrous.
Morphology Leaves
Leaf-blades 10–25 cm. long, 3–15 mm. wide; ligule a line of hairs; sheaths glabrous, or pubescent above.
Morphology Reproductive morphology Inflorescences
Inflorescence linear to lanceolate, 8–20 cm. long, typically dense with the racemes overlapping to form a head but sometimes interrupted; racemes simple, 2–4 cm. long, the spikelets closely packed.

Lake shores; 1200–1700 m.
