A shrub, branches woolly villous, with whitish hairs which at length fall off.

Heads solitary, terminal, broadly campanulate, about 1.5 cm long and 1-1.3 cm in diameter. Involucral bracts 5-7-seriate; the outermost oblong-elliptic, rounded at the apex, about 4 mm long, glabrous, with finely membranous hyaline margins which at length become jagged; the innermost oblong, about 1 cm long with rounded slightly broader apices and more membranous than the outer ones. Receptacle not examined. Corolla tube gradually widened upwards, nearly 1 cm long, glabrous, lobes linear-lanceolate, subacute, 2 mm long. Achenes about 5 mm long, very densely appressed silky-villous. Pappus brownish straw-coloured, 8-10 mm long.
