Plants forming dense to rather open clumps. Rhizomes pachymorph, neck 3--10 cm long. Culms  to 6 m, to 2 cm in diam., nodding; internodes to 25 cm, terete, with quickly deciduous blue-grey wax at first, becoming dark green, longitudinal ridges very prominent, glabrous, cavity small, wall thick; nodes slightly raised, , supra-nodal ridge obscure, sheath scar thin, glabrous; branches initially (3)-5-(7), long, nearly horizontal. Culm sheaths deciduous, shorter or longer than internodes, apically retuse with depressed ligule, papery to tough, initially light green, often mottled where exposed, brown-setose, proximally glabrous but initially with dense ring of longer hairs around base, longitudinal ribs not coloured, margins densely long-ciliate; auricles absent; oral setae few, erect, to 6 mm; ligule to 2 mm, depressed, serrate and ciliate, tomentose; blade linear, glabrous, erect or reflexed and recurved, quite persistent. Leaves 4--6 per ultimate branch; sheath nearly glabrous, often apically pink-tinged, margins glabrous; auricles absent or tiny; oral setae few, erect, to 4 mm; ligule convex, to 1 mm, tomentose; external ligule very shortly ciliate; blade broadly lanceolate, to 10 0.9 cm, dark green above, base rounded, abaxial proximally sparsely pilose beside midrib, secondary veins 3-paired, margins finely spinescent, transverse veins clear. Synflorescence unknown. Name nujiangensis Latin, from near the Nujiang (Salween) River.

Tall, narrow, thick-walled culms with narrow foliage leaves. Some blue-grey wax at first on the young culms. A very elegant and reasonably hardy bamboo.

 

 

 

 

 

 

 

 

 

Type locality for B nujiangensis  in Google Earth Introduced into Holland in 1995 (Yunnan 95-3c), collected by Shanghai Botanic Garden, origin unknown. On arrival plants identified in Holland as Fargesia yulongshanensis, but later considered closer to Borinda nujiangensis.
