Petalacte

Perennial herbs or shrublets. Leaves alternate, sessile, narrowly obovate-spathulate, narrowly elliptic or narrowly panduriform, margins entire, flat or revolute, densely tomentose to woolly (hair type B). Capitula disciform, small, aggregated into terminal cymes or corymbs, several-flowered, pedunculate, densely woolly. Involucre +/- obovoid; bracts in 4 rows, imbricate, stipitate, woolly, inner large, ovate, petaloid, white; stereome undivided. Receptacle flat, paleate; paleae linear, +/- as long as florets, outermost resembling involucral bracts. Marginalflorets female, few, filiform or narrowly tubular, minutely 5-toothed and glandular at apex. Discflorets functionally male, outnumbering female florets; corolla tubular, narrowly campanulate above, 5-lobed and glandular at apex. Anthers ecalcarate, caudate; with oblong-lanceolate, terminal appendage; endothecial tissue polarised. Style in female flowers bifid; branches flattened, linear, obtuse-truncate and with obtuse sweeping hairs apically. Cypselas narrowly elliptic, brownish, glabrous or with elongated, nonmyxogenic twin hairs, often subtended by short, scarious, apically laciniate scale. Pappus in male flowers of 10-15 bristles in 1 row, as long as to slightly longer than corolla tube, sparsely barbellate to nude below and subplumose at apex, free below; in female flowers more poorly developed.
