Description of the genus
Annual or perennial herbs (often with annual stems from woody rootstocks), small to large shrubs, woody scramblers or small trees. Leaves alternate, simple. Capitula homogamous, discoid; florets normally bisexual and fertile. Phyllaries free in 2-many series, imbricate. Corolla various shades of purple, blue, or creamy-white, regularly 5-lobed. Pappus 2-seriate with an outer short whorl of scales or setae and an inner whorl of longer setae. Derivation of name: Named after William Vernon, English botanist of the late 17th century. Comment: Studies, since the 1970s, based on chromosome counts, chemistry, pollen and DNA, have shown that the genus Vernonia is paraphyletic with two centres of origin, one in S America and one in Africa and SE Asia (Herman & Swelankomo, 2011). Worldwide: c. 1,000 species in warm and tropical regions of the Old World and America Zimbabwe: 55 taxa. Insects associated with this genus:
