Comptonanthus B. Nord.Trichogyne Less.
Annual herbs (outside the area perennial and shrubby species occur). Leaves alternate, sometimes opposite below, linear to linear-lanceolate, variously tomentose, often more strongly on the upper surface. Capitula usually heterogamous, solitary or variously aggregated; phyllaries pluriseriate, brownish, stereome divided, usually cymbiform and subtending a female floret, the inner flattish and surrounding the bisexual florets (in one subgenus functionally male with aborted ovary). Corolla of female florets filiform, of bisexual cylindric or campanulate, yellow. Style-branches truncate and penicillate in fertile bisexual florets. Anther bases sagittate. Cypselas with globose myxogenic twin hairs; pappus absent in female florets, in the bisexual florets setae shortly plumose in upper part.
A mainly S. African genus with c. 15 species. The pappus setae which are plumose above are characteristic and the leaves show a typical indumentum especially on the lower side described as 'thin tissue-paperlike' by Hilliard, l.c. 1981. Represented here by the following species:
