Capillipedium huegelii

HABIT Annual. Culms decumbent; 80–100 cm long; rooting from lower nodes. Culm-nodes bearded. Leaf-sheath oral hairs ciliate. Ligule a ciliolate membrane. Leaf-blades 10–15 cm long; 8–12 mm wide. Leaf-blade surface scabrous; rough on both sides.

INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme.

Panicle open; oblong; 8–12 cm long.

Racemes 0.7 cm long; bearing few fertile spikelets; bearing 2–3 fertile spikelets on each. Rhachis ciliate on margins. Rhachis internodes linear; 3 mm long.

Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; 3 mm long; with a translucent median line (also present in internodes); ciliate.

STERILE SPIKELETS Companion sterile spikelets well-developed; male; lanceolate; 3–4 mm long; as long as fertile; separately deciduous. Companion sterile spikelet glumes 9 -veined; pubescent. Companion sterile spikelet lemmas enclosed by glumes.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 3–4 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base obtuse; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; membranous; without keels; 7 -veined. Lower glume surface concave; pubescent; hairy below. Upper glume lanceolate; 1 length of spikelet; 1-keeled; 3 -veined.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline; 0 -veined; without midvein; without lateral veins. Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma apex entire; acute; awned. Principal lemma awn geniculate; 14–16 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.

FLOWER Anthers 3; 1.8 mm long.

DISTRIBUTION Asia-tropical: India.

NOTES Andropogoneae. Hackel 1994.
