Capillipedium kuoi

HABIT Perennial; caespitose; clumped loosely. Culms erect, or geniculately ascending; 50–110 cm long; 1.5–2.3 mm diam.; firm. Culm-nodes pubescent. Lateral branches sparse. Leaf-sheaths glabrous on surface, or pilose; with tubercle-based hairs. Ligule a ciliolate membrane; 1.6 mm long. Leaf-blades linear; 10–20 cm long; 5–8 mm wide. Leaf-blade surface glabrous, or pubescent; sparsely hairy.

INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme.

Panicle open; ovate; 10–18 cm long. Panicle branches capillary; bearded in axils.

Racemes bearing few fertile spikelets; 2–4 fertile spikelets on each. Rhachis ciliate on margins.

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; male; lanceolate; as long as fertile, or longer than fertile; separately deciduous. 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 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base obtuse; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate, or elliptic; 1 length of spikelet; membranous; 2-keeled; keeled obtusely. Lower glume intercarinal veins distinct; 4–6 in number. Lower glume surface concave; pilose. Lower glume margins ciliate. Lower glume apex erose. Upper glume ovate; 1-keeled. Upper glume surface glabrous.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline. Fertile lemma linear; hyaline; without keel. Lemma apex entire; acute; awned; 1 -awned. Principal lemma awn geniculate; 8–12 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.

DISTRIBUTION Asia-temperate: China.

NOTES Andropogoneae. Fl China 2004.
