Oxytenanthera braunii

Bamboo, in dense clumps; culms 3–10 m. high, 5–10 cm. in diameter, erect, at first densely silky with appressed hairs, solid or thick-walled; culm-sheaths with dark brown bristly hairs, tipped with an involute pungent blade 1–2 cm. long. Leaf-blades linear-lanceolate to lanceolate, 5–25 cm. long and 1–3 cm. wide, somewhat glaucous, with inconspicuous transverse veins, gradually narrowed to a fine pungent tip; leaf-sheaths with a few deciduous setae 2–5 mm. long on the shoulders, without auricles. Spikelet-clusters globose, sometimes ± confluent, 4–8 cm. across, spiny; bracts ovate, up to 4 mm. long, rounded on the back (except the lowest which is 2-keeled). Spikelets very narrowly lanceolate, 15–40 mm. long, 1–4-flowered, 1 or sometimes 2 upper florets hermaphrodite, the rest reduced to lemmas; glumes ovate to oblong, ± shortly hispidulous, obtuse to acute, the lower 5–8 mm. long, the upper 8–10 mm. long; lemmas narrowly lanceolate, the lowest 12–20 mm. long, the uppermost about as long as the spikelet, ± hispid on the back, tipped by a rigid spine up to 7 mm. long; palea narrowly lanceolate, a little shorter than the lemma.
