From Bamboos of Thailand, Native and Introduced Species (Poaceae: Bambusoideae) — An Annotated Compilation, by D. Ohrnberger (Khun Dieter – คุณดีเท่อร์)
Characteristics: Habit open caespitose. Rhizome to about 40 cm long, pachymorph, distally usually thicker than the culm. Culms straight, erect, slightly bending above, ultimate height over 12 m. Young shoots conical, sheaths initially greenish, changing to pale orange soon, farinose and scattered with dark hairs; culm-leaf blades initially erect on the top, spreading on elongated shoots, the lower ones somewhat deflexed, greenish, glabrous, with conspicuous pale bristly dark colored auricles; emerge from March to November. Culm-internodes terete, 50–60 (69) cm long, glabrous, green, and farinose (thus appearing bluish green) when young, dull green when old; basal diameter to about 7.5 cm; thick-walled, wall 1.0–1.3 cm by 4.5–5.0 cm in diameter at 1.1 m above the ground. Culm-nodes glabrous, smooth, flat (slightly prominent in thin culms); sheath scar not or marginally protruding; supranodal line discernible, with or without a slight ridge, about 1 cm above the nodal line; with a white farinose ring below the sheath scar when young; occasionally with short aerial roots on the basal culm. Branch-buds solitary, rotund, from the basal node up. Branches initially 3, central one dominant, to ca. 2 m long, two side branches subdominant, with a few to several additional smaller branches on the upper culm; usually unbranched on the lower culm, but a single thick branch may occasionally develop; branching intravaginal; rebranching. Culm-leaves deciduous, the very basal ones may occasionally remain persistent and decay on the culm. Culm-leaf sheaths an isosceles trapezoid, 10–12 cm long, one-fifth to one-sixth as long as the internode, thickly papery, glabrous, light brownish green, evenly covered with a white mealy-waxy, easily removable deposit when young, thus appearing bluish, light straw-colored when dry; margins eciliate; apex horizontal-truncate, symmetrical or slightly asymmetrical. Culm-leaf auricles conspicuous long lobes, adnate to and contiguous with the basal margin of the blade, extending to the sheath margin and protruding the margin almost 1 cm, each auricle 3–4 cm long, 0.5–1 cm high, waved, horizontally deflexed, margin throughout with 0.5–2 cm long light brownish horizontally oriented and waved bristles. Culm-leaf ligule 2–4 mm high (to 5 mm in the middle), entire, eciliate, blackish when young. Culm-leaf blades coriaceous, caducous, deflexed to horizontally deflexed, green and glabrous on both surfaces, light straw-colored when dry, broadly lanceolate, 4–6 cm long, 2–3 cm wide on the lower culm, about half as long as a sheath on the lower and mid-culm, and as long as a sheath on the upper culm; junction with sheath about to 3 cm wide; apex attenuate. Foliage-leaves (8) 9–10 (11) per branchlet. Foliage-leaf sheaths keeled, mid-green, glabrous, smooth, margins eciliate. Foliage-leaf auricles none, bristles none. Foliage-leaf ligule 2–3 mm high, green, entire; outer ligule small, callus-like. Foliage-leaf blades tough, medium-sized, (15) 24–33 (42) × (2) 3–5 (7) cm, lanceolate to oblong-lanceolate, glabrous on both surfaces, mid to dark green above, bluish-green beneath; base unequally rounded to wedge-shaped; apex attenuate; margins antrorsely scabrous; midrib proximally prominent on both surfaces, yellowish green beneath; pseudopetiole 2–4 mm long. Flowers and seeds are unknown.
