Plants spreading widely and forming dense, separated clumps. Culms to 10 m tall, to 5 cm in diam., pluricaespitose, suberect; internodes sulcate above branches, finely ridged, glossy above and below nodes, glaucous and matt with dense persistent white wax elsewhere; nodes with level, acute sheath scar; supranodal ridge prominent. Culm sheaths tough, deciduous, convexly attenuating to narrow apex, apically asymmetrical, with brown appressed hairs at apex and base, and more widespread erect hairs at first; auricles absent; oral setae sparse, scabrous and erect, or absent; ligule arcuate, to 10mm wide, to 2 mm deep, arcuate, densely pubescent, margin fimbriate at first; blade small, narrowly lanceolate, deciduous, reflexed or erect, adaxial scabrous. Leaf sheaths persistent, glabrous, purple above, margins membranous and lightly ciliate at first; ligule very long, to 4 mm, densely pubescent and ciliate to fimbriate at first; auricles absent; oral setae very scarce or absent; blade to 25 cm long, to 3.5 cm wide,tough,dark glossy green above,abaxiallightly tomentose; petiole glabrous. Named after Paul Guillaume Farges, nineteenth century missionary and plant collector in China.
A handsome and vigorous bamboo, but invasive. A smaller and possibly hardier species, distinguished by a more prominent, more projecting ring of hairs on the culm sheath base and more ciliate leaf sheaths, tentatively identified as B. qinchengshanensis, is also in cultivation.
