1. B. diversifolia (leaves of vacio us forms), Flsch. and Mey. Ind. \i.\ Sem. 

 Hort. Petrop. 31 ; Benth. Fl. Aiistr. iii. 511. A tufted perennial, flowering 

 however the first year so as to appear annual, glabrous or hirsute with septate 

 hairs. Stems usually simple, 1 to 2ft. high or rarely reduced to a short scape. 

 Lower leaves often crowded, obovate spathulate or oblong, coarsely toothed or 

 pinnatifid, the lobes broad or narrow, sometimes again divided, the upper leaves 

 smaller and less divided, and the upper part of the stem a long almost leafless 

 peduncle. Flower-heads larger than in any other species. Involucre above Jin. 

 diameter, the scarious margins of the bracts broad. Kay-florets white, long and 

 numerous. Style-branches with a lanceolate papillose appendage, but without 

 the longer hairs at the base figured by Lessing (Syn. Comp. f. 16). Achenes 

 oblong, thickened upwards, marked with longitudinal furrows, the outer ones 

 obliquely incurved at the top, with a dense tuft of short capillary bristles. — Hook,
