Brachiaria nilagirica

HABIT Annual; caespitose. Culms decumbent; 15–35 cm long; rooting from lower nodes. Leaf-sheaths striately veined. Ligule a fringe of hairs. Leaf-blade base broadly rounded. Leaf-blades ovate; 2–3 cm long; 8–9 mm wide. Leaf-blade surface pilose; sparsely hairy; hairy adaxially, or abaxially. Leaf-blade margins cartilaginous; crenate. Leaf-blade apex acute.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 5–7; borne along a central axis; closely spaced; unilateral; 1–1.5 cm long; simple, or with branchlets at base of longer racemes; secondary branches glomerate. Central inflorescence axis 2–3 cm long; puberulous to pilose. Rhachis wingless; angular; puberulous on surface to pilose on surface. Spikelet packing irregular.

Spikelets in pairs. Fertile spikelets pedicelled. Pedicels linear, or oblong; ciliate.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; acute; 2.5–3.5 mm long; falling entire.

GLUMES Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume elliptic; 2 mm long; 0.8 length of spikelet; cartilaginous; without keels; 3 -veined. Lower glume surface grooved on either side of midvein. Lower glume apex acute. Upper glume elliptic; 2.5 mm long; 1 length of spikelet; cartilaginous; without keels; 5 -veined. Upper glume surface glabrous. Upper glume apex acute.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; cartilaginous; 5 -veined; obscurely veined; glabrous; acute. Fertile lemma elliptic; 2–2.25 mm long; indurate; without keel; 5 -veined. Lemma surface striate. Lemma margins involute. Lemma apex acute. Palea involute; indurate; without keels.

FLOWER Anthers 3; 0.5 mm long; purple.

DISTRIBUTION Asia-tropical: India.

NOTES Paniceae. Bor.
