Capillipedium laoticum
HABIT Annual. Culms 70–80 cm long. Culm-internodes distally glabrous. Culm-nodes bearded. Leaf-sheaths striately veined. Ligule a ciliate membrane. Leaf-blades 15–20 cm long; 2 mm wide.
INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme.
Panicle open; oblong; 8–9 cm long. Panicle axis glabrous. Panicle branches hirsute (2–3mm hairs); hairy at tip.
Racemes 8–10 cm long; bearing few fertile spikelets; bearing 2–3 fertile spikelets on each. Rhachis fragile at the nodes; subterete; ciliate on margins. Rhachis internodes filiform; 0.75 length of fertile spikelet.
Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform; 0.75 length of fertile spikelet; with a translucent median line (also present in internodes); ciliate.
STERILE SPIKELETS Companion sterile spikelets well-developed; containing empty lemmas; oblong; 3 mm long; shorter than fertile; separately deciduous. Companion sterile spikelet glumes chartaceous; 8–9 -veined; scaberulous; muticous. Companion sterile spikelet lemmas 1; enclosed by glumes; 1 mm long.
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 bearded; base obtuse; attached transversely. Spikelet callus hairs 0.33 length of spikelet.
GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; chartaceous; pallid; 2-keeled; keeled obtusely. Lower glume surface concave; asperulous; rough above. Lower glume margins ciliate. Lower glume apex truncate. Upper glume lanceolate, or oblong; chartaceous; 1-keeled. Upper glume apex acute.
FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline. Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma apex entire; acute; awned; 1 -awned. Principal lemma awn geniculate; 35–40 mm long overall; with twisted column. Column of lemma awn 5 mm long; glabrous. Palea absent or minute.
FLOWER Anthers 3.
DISTRIBUTION Asia-tropical: Indo-China.
