9B3DC47E2B26FFBA76A6199B4B7AE2C9.taxon	description	Description: — Shrubby or arborescent bamboo. Rhizomes leptomorph; internodes cylindrical, 2 – 7 cm long, 8 – 10 mm in diameter, nearly solid; nodes prominent, 4 – 6 roots at each node; rhizome buds triangular-ovate to ovate, margins brown ciliate. Culms pluricaespitose, erect, 3 – 6 m tall and 1.0 – 2.5 cm in diameter; internodes terete, (10 –) 25 – 35 (– 40) cm long, basally weakly flattened above branches, initially covered with thick white powder, glabrous; walls 2 – 5 mm thick; pith lamellate; supranodal ridges not conspicuous; sheath scars prominent, corky, with persistent remains of sheath base. Intranodal region ca 5 mm high, thinly white powdery but darkened by contamination when old, glabrous. Primary buds solitary, triangular-ovate, not sunken into culm, margins densely brown ciliate except base. Branches erect, 3 – 5 per mid-culm node, subequal, 30 – 55 cm long, inclined at an angle of 15 ° – 40 ° with the culm, branch sheaths thinly leathery, shorter than internodes, abaxially glabrous, with unevenly scattered black dots, margins sparsely ciliate. Culm leaf: sheaths long triangular, caducous, thinly leathery, oily, glossy, with pungent smell, 20.5 – 32.0 × 5 – 10 cm, 2 / 3 – 11 / 10 as long as internodes, initially yellowish green, brown when dry, abaxial surface glabrous except base with a ring of dense brown setae that are 0.5 – 7 mm long, with densely dark brown dotted lines between veins, and one black line near the margin of each side of sheath apex, margins sparsely ciliate; auricles absent or present, falcate and densely pubescent when present; oral setae erect, radiate, rigid, scabrid, pale yellow, 3 – 10 mm long, easily deciduous when old; ligules arcuate to truncate, 1 – 5 mm tall, entire, with a black band at base, band 1 mm tall, densely pubescent, glabrescent when old; blades reflexed, linear-lanceolate, caducous, 3.0 – 16.5 × 0.2 – 0.8 cm, ca 1 / 2 – 3 / 5 as long as sheath, base slightly narrowed, both sides glabrous, margins serrulate. Foliage leaves 2 – 5 per ultimate branch: sheaths 5.5 – 7.0 cm long, glabrous, longitudinal ribs conspicuous; auricles and oral setae absent; ligule convex to truncate, 1 – 2 mm tall, green in vivo, purple when dry, entire, abaxially pubescent, apex ciliate; outer ligule truncate, ca 0.5 mm tall, ca 2 mm wide, entire, apex pubescent; pseudo-petioles 2 – 5 × 0.5 – 1.5 mm, glabrous; leaf blades lanceolate, papyraceous, 9 – 21 × 1.2 – 2.5 cm, base widely cuneate or truncate, apex acute, glabrous on both surfaces, margins serrulate along both sides, secondary veins 5 – 7 pairs, transverse veins slightly conspicuous. Inflorescence unknown.	en	Niu, Zheng-Yang, Tong, Yi-Hua, Xia, Nian-He (2021): Pleioblastus triangulata (Poaceae: Bambusoideae), a new combination for Indosasa triangulata based on morphological and molecular evidence.
