Perennial from woody base, shrub, dioecious, glabrous or finely hairy, often glandular and sticky or shiny.
Stem: generally erect or ascending, round or often striate-angled, generally green.
Leaf: cauline, alternate, sessile to short-petioled, linear to (ob) ovate, entire or toothed, distally occasionally reduced to bracts.
Inflorescence: heads of 2 kinds, unisexual; discoid ( staminate) and disciform ( pistillate), 1 or in terminal or lateral raceme- or panicle-like or ± flat-topped clusters; phyllaries lanceolate to ovate, graduated in several series; receptacle flat to conic, epaleate, smooth or pitted.
Pistillate flower: 8–150; corolla narrowly tubular, ± white, lobes vestigial; style branches linear, ± glabrous.
Staminate flower: 8–48; corolla white to pale yellow, 5-lobed; anther tip oblong-triangular; style tips erect, club-shaped or oblong to linear, densely papillate to minutely bristly, ovary much reduced; pappus of many equal bristles.
Fruit: ± cylindric, 5–10-ribbed; pappus of many bristles, generally elongating and exceeding phyllaries in fruit, ± white to tawny.
350–450 species: Am. (Latin: Bacchus, god of wine) [Sundberg & Bogler 2006 FNANM 20:23–34]
