Capillipedium longisetosum
HABIT Annual. Culms geniculately ascending, or decumbent; 20–40 cm long. Culm-nodes bearded. Leaf-sheaths keeled; glabrous on surface, or puberulous. Ligule a ciliolate membrane; 1.5 mm long. Leaf-blades flat, or revolute; 5–10 cm long; 3 mm wide. Leaf-blade surface scabrous; rough adaxially; pilose; sparsely hairy; hairy adaxially; with tubercle-based hairs.
INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme.
Panicle open; oblong; 8 cm long; 4–5 cm wide. Panicle branches flexuous; bearded in axils.
Racemes 0.7–1 cm long; bearing few fertile spikelets; bearing 3–4 fertile spikelets on each. Rhachis ciliate on margins. Rhachis internodes linear.
Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; with a translucent median line (also present in internodes); ciliate.
STERILE SPIKELETS Companion sterile spikelets well-developed; comprising 2 subequal glumes without lemmas; lanceolate; 3–3.25 mm long; shorter than fertile; separately deciduous. Companion sterile spikelet glumes 9 -veined.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 3.5 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; 9 -veined. Lower glume surface concave; asperulous; rough at apex. Lower glume apex obtuse. 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 bigeniculate; 40 mm long overall; with twisted column. Column of lemma awn 20 mm long; glabrous. Palea absent or minute.
FLOWER Anthers 3; 1.75 mm long.
DISTRIBUTION Asia-tropical: Indo-China.
