Capillipedium assimile
HABIT Perennial. Culms decumbent; 150–300 cm long; woody; rooting from lower nodes. Culm-nodes bearded. Lateral branches suffrutescent. Ligule a ciliolate membrane. Leaf-blade base tapering to the midrib, or simple. Leaf-blades linear, or lanceolate; 6–20 cm long; 3–6(–12) mm wide; flaccid. Leaf-blade midrib widened.
INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme.
Panicle open; oblong; 5–12 cm long; 3–4 cm wide. Primary panicle branches whorled at lower nodes. Panicle branches capillary; glabrous in axils, or bearded in axils.
Racemes bearing few fertile spikelets; 2–6 fertile spikelets on each.
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; male; lanceolate; 3–4.5 mm long; 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; 1.8–2.5 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 intercarinal veins distinct; 2–4 in number. Lower glume surface concave; scabrous; glabrous, or puberulous. Upper glume ovate; 1-keeled; 3 -veined. Upper glume primary vein scaberulous.
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; 1 -awned. Principal lemma awn geniculate; 6–12 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
FLOWER Anthers 3.
DISTRIBUTION Asia-temperate: China and eastern Asia. Asia-tropical: India, Indo-China, and Malesia. Pacific: southwestern.
