Dimeria kurzii

HABIT Annual. Culms slender; 30–60 cm long. Culm-nodes bearded. Leaf-sheaths keeled; pilose; with tubercle-based hairs. Ligule a ciliolate membrane; 0.5–1 mm long. Leaf-blades 4–8 cm long; 2–3.5 mm wide. Leaf-blade midrib prominent beneath. Leaf-blade surface scaberulous; pilose; hairy on both sides; with tubercle-based hairs. Leaf-blade margins tuberculate-ciliate. Leaf-blade apex acute.

INFLORESCENCE Inflorescence composed of racemes. Peduncle widened at apex.

Racemes 1; single; straight, or arcuate; unilateral; 3.5–5.5 cm long. Rhachis ciliate on margins. Spikelet packing crowded; regular; 2 -rowed.

Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels reduced to a stump; flattened.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; compressed strongly; 3–3.5 mm long; falling entire. Spikelet callus bearded; base obtuse.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 2.5 mm long; 0.75–0.85 length of spikelet; coriaceous; 1-keeled. Lower glume primary vein ciliate. Lower glume surface pubescent; hairy below. Lower glume apex acute; muticous, or mucronate. Upper glume elliptic; 3–3.5 mm long; 1 length of spikelet; coriaceous; 1-keeled; wingless; 3 -veined. Upper glume primary vein ciliate. Upper glume surface pilose; hairy on veins. Upper glume apex acuminate.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 1.5 mm long; hyaline. Fertile lemma elliptic; 2 mm long; hyaline; without keel; 1 -veined. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 12–18 mm long overall; with twisted column. Column of lemma awn 4 mm long; glabrous. Palea absent or minute.

FLOWER Anthers 2; 0.6 mm long.

DISTRIBUTION Asia-tropical: India, Indo-China, and Malesia.

NOTES Andropogoneae. Bor 1993.
