Sympodial bamboo, loosely tufted. Rhizomes pachymorph. Culms erect, lower nodes with verticillate aerial roots, apically pendulous, 9-14 m tall, 5-9 cm in diameter; internodes terete, greyish-green, yellow striped, 20-40 cm long, wall 7-12 mm thick, culm surface initially densely covered with white to brown hairs when young and glabrous or patchy smudge later; nodes inconspicuous, internode 7-10 mm tall, with a ring of white tomentum at the intranode and below the node. Culm sheaths deciduous, leathery, adaxially glabrous, abaxially sparsely hispidous with brown to black deciduous hairs, strigose, 20-28 cm long, hay colour, with truncate apex; auricles narrowly falcate, 7-10 mm wide, 1-2 mm tall; ligules 4-6 mm tall, denticulate; blades triangular, erect, 4-7 cm long, 1/2 as wide as the apex of culm sheaths. Bud ovate, branching high, from 3-4 m above ground, branches several, one dominant. Foliage leaves 8-12 per ultimate branchlet, usually 10; sheaths initially sparsely white hairy and later glabrous, keeled; auricles inconspicuous; ligules ca. 2 mm tall, entire or split; collar with external ligule; blades lanceolate, 10-28 (-40) cm

Pseudospikelets narrowly ovate, light green, 12-18 mm long, 2-3 mm wide; fertile ones sessile, perfect fertile florets 2-4, with diminished florets at the apex; disarticulated above glumes, but not between florets; rhachilla internodes compressed between florets. Glumes 2-3, broadly ovate, persistent, veined, 5-9 mm long, 4-6 mm wide, margins ciliated at upper half. Fertile lemma lanceolate, 14-16 mm long, chartaceous, apex mucronate, glabrous abaxially, margins ciliated; palea oblanceolate, 2-keeled, equal length to lemma, keels and margins long ciliated; lodicules absent; anthers 6, 8-10 mm long, yellow, with a finely-toothed gradual apical tip 0.5-1 mm long, filaments united into a firm tube, 6-10 mm long; stigmas one, purple, plumose, ovary umbonate, pubescent apically.
