Capillipedium kwashotense

HABIT Perennial. Culms decumbent; 15–30 cm long. Lateral branches sparse. Ligule a ciliolate membrane. Leaf-blades 6–10 cm long; 3–5 mm wide.

INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme.

Panicle open; lanceolate, or ovate; 4–8 cm long; 1–3 cm wide. Primary panicle branches 1–2 -nate; simple, or sparsely divided. Panicle branches capillary.

Racemes 1 cm long; bearing few fertile spikelets; bearing 3–5 fertile spikelets on each. Rhachis fragile at the nodes. 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).

STERILE SPIKELETS Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; shorter 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 lanceolate, or ovate; dorsally compressed; 3–3.2 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base obtuse; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; membranous; 2-keeled; keeled obtusely. Lower glume surface flat. Lower glume apex truncate. Upper glume ovate; 1-keeled.

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; 10–16 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.

FLOWER Anthers 3.

DISTRIBUTION Asia-temperate: eastern Asia. Asia-tropical: Malesia.
