Plants forming dense clumps. Rhizomes pachymorph, neck 3--6 cm long. Culms  to 7 m, to 4 cm in diam., nodding to pendulous; internodes to 25 cm, terete, lightly blue-grey waxy for first year, becoming yellow-green, longitudinal ridges very prominent, distally grey tomentose and apically densely brown setose, cavity large; nodes distinct but not swollen on larger culms, supra-nodal ridge obscure, sheath scar prominent and initially dark; branches initially (3)-5-(7), central stronger. Culm sheaths deciduous, similar in length to internodes, papery to thick, initially light green or purple, lightly brown-setose, more densely at the base, apex narrow, longitudinal ribs not coloured, margins initially distally shortly ciliate; auricles absent or very small; oral setae few, erect, white; ligule to 5 mm, eroded, finely ciliate, glabrous; blade linear, long, glabrous, reflexed, often purple, quite persistent, margins usually glabrous. Leaves 4--8 per ultimate branch, basal blades clustered; sheath variably pubescent, margin ciliate, often dark purple; auricles small, rounded; oral setae few, erect or spreading, stout, light brown or purple-tinged, ca. 1--4 mm, basally scabrous; ligule truncate, to 1 mm, tomentose, shortly ciliate; external ligule shortly white-ciliate; blade narrowly lanceolate to lanceolate, to 15 1.5 cm, fresh mid-green, abaxially pubescent, densely pubescent at cuneate base, secondary veins 3-5-paired, margins spinescent-serrulate, transverse veins distinct; petiole long, abaxially pubescent. Name macclureana Latin, in honour of bamboo pioneer and taxonomist Dr Floyd Alonzo McClure (1897-1970).

Moderately sized variably waxy, densely hairy culm internodes, apically setose, with setose sheaths. Foliage leaves of small to intermediate size with variously hairy sheaths and lower surfaces, and variable auricles with short scabrous bristles. Clones vary substantially in size and habit, with some hardy below about -15C, and often with prominent dark purple colouration to branches and sheaths after exposure.

Collection localities in Google Earth About 40 separate introductions into England of Borinda macclureana or closely related bamboos were made, from 10 areas of SE Tibet Surviving collection placenames in Google Earth, by plant collector Keith Rushforth on 4 collecting trips in the 1990s.  Images from Google Earth of KR collection localities and area placenames.
