Like B. abrotanoides but leaves acuminate, incurved in upper half. Usually 1.5-2 m high, with pilose branchlets. Leaves mostly 0.8-1 cm long, erect-spreading, spreading or slightly reflexed, linear-lanceolate, attenuate, prominently keeled on both surfaces, tetragonal towards the apex, slightly incurved above the middle, at first pilose, soon becoming glabrous. Flowering heads usually 1-1.3 cm wide, globose, terminating short leafy branchlets, clustered in almost corymbose formations. Bract and bracteoles almost as long or slightly longer than the flower, oblanceolate, attenuate towards both ends, with caducous hairs on the dorsal surface. Calyx-tube oblong, slightly widened above the middle, clothed with long caducous unicellular hairs: calyx-lobes decurrent on the tube, lanceolate-acicular, setaceo-acuminate, reaching the middle of the petals. Petals 2.5-3 mm long, elliptic (widest at the middle), tapering towards both ends, obtuse, with long caducous hairs on the lower half of the dorsal surface, cream-coloured, with 2 keels from the middle downwards. Stamens much exerted: anthers 1 mm long, linear-oblong: thecae free 2/3 of their length. Ovary almost entirely inferior. Fruit unknown. Usually 1.5-2 m high, with pilose branchlets.

The affinity is with B. intermedia from which it is distinguished by much longer leaves, larger flower-heads and by petals tapering towards both ends.
