Capillipedium nagense
HABIT Perennial. Rhizomes elongated. Culms erect; 50–60 cm long. Culm-nodes bearded. Leaf-sheaths keeled; glabrous on surface, or pilose; with tubercle-based hairs. Ligule a ciliolate membrane; 1 mm long. Leaf-blades 6–12 cm long; 2–4 mm wide. Leaf-blade surface pilose; sparsely hairy; hairy on both sides; with tubercle-based hairs. Leaf-blade apex acuminate.
INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme.
Panicle open; oblong; 8 cm long; 2 cm wide. Panicle branches bearded in axils.
Racemes 1–1.5 cm long; bearing few fertile spikelets; bearing 4–6 fertile spikelets on each. Rhachis ciliate on margins. Rhachis internodes linear; 2.5 mm long.
Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; 2.5 mm long; with a translucent median line (also present in internodes); ciliate.
STERILE SPIKELETS Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 5 mm long; longer than fertile; separately deciduous. Companion sterile spikelet glumes 9 -veined. 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; 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; 9 -veined. Lower glume surface concave. 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; 2.5–2.75 mm long; 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; 19–20 mm long overall; with twisted column. Column of lemma awn 8 mm long; glabrous. Palea absent or minute.
FLOWER Anthers 3; 2.5 mm long.
DISTRIBUTION Asia-tropical: India.
