Brachiaria remota

HABIT Perennial. Culms decumbent, or prostrate; 30–60 cm long. Culm-nodes glabrous, or pubescent. Ligule a fringe of hairs. Leaf-blades 5–10 cm long; 2.5–3 mm wide; glaucous. Leaf-blade surface glabrous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 3–5; borne along a central axis; distant; unilateral; 1–6 cm long. Central inflorescence axis 2–15 cm long. Rhachis wingless; angular. Spikelet packing adaxial; distant; irregular.

Spikelets solitary, or in pairs. Fertile spikelets pedicelled. Pedicels linear.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; compressed slightly; obtuse; 2.5–3 mm long; falling entire. Rhachilla internodes elongated between glumes. Rhachilla elongation 0.3 mm long.

GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; clasping; 0.33 length of spikelet; membranous; without keels; 3–5 -veined. Lower glume apex acute. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 5–7 -veined. Upper glume surface glabrous, or pubescent. Upper glume apex obtuse.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; membranous; 5 -veined; obtuse. Fertile lemma elliptic; 2.5–3 mm long; indurate; without keel. Lemma surface rugulose. Lemma margins involute. Lemma apex acute. Palea involute; indurate; without keels.

DISTRIBUTION Asia-temperate: Arabia. Asia-tropical: India.

NOTES Paniceae. Senaratna.
