Capillipedium magdalenii
HABIT Annual. Culms erect; 20 cm long. Culm-internodes 2–3 cm long. Culm-nodes glabrous. Lateral branches ample. Leaf-sheaths 3 cm long; mostly shorter than adjacent culm internode. Ligule a ciliolate membrane; acute. Leaf-blades conduplicate, or involute; 2–4 cm long; 3 mm wide.
INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme.
Panicle open; 1–2 cm long. Panicle branches capillary.
Racemes bearing a triad of spikelets, or few fertile spikelets; 1–4 fertile spikelets on each. Rhachis evident, or obsolete; fragile at the nodes; glabrous on margins.
Spikelets in pairs, or in threes. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster, or 2 in the cluster. Pedicels linear; 1 mm long; with a translucent median line (also present in internodes).
STERILE SPIKELETS Companion sterile spikelets well-developed; containing empty lemmas; lanceolate; 3 mm long; longer than fertile; separately deciduous. Companion sterile spikelet glumes 7–9 -veined. Companion sterile spikelet lemmas enclosed by glumes.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets linear, or lanceolate; dorsally compressed; 2 mm long; falling entire; deciduous with accessory branch structures.
GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume linear, or lanceolate; 1 length of spikelet; chartaceous; 2-keeled; keeled laterally; keeled obtusely; 5 -veined. Lower glume surface concave; pubescent. Upper glume lanceolate; 1.5 mm long; chartaceous; 1-keeled; 3 -veined.
FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret linear; 1 mm long; 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; 60 mm long overall; with twisted column. Palea absent or minute.
FLOWER Anthers 3; 1.5 mm long.
DISTRIBUTION Asia-tropical: India.
