BILLY BUTTONS

Craspedia is a genus of flowering plants in the daisy family commonly known as billy buttons and woollyheads. They are native to Australia and New Zealand where they grow in a variety of habitats from sea level to the Alps. The genus is found in every state of Australia except the Northern Territory. In New Zealand, Craspedia is found from East Cape on the North Island south to Stewart Island. It also occurs on Campbell Island and the Chatham Islands. There are about 23 species: 6 from New Zealand and 17 from Australia.

Craspedia are rosette-forming herbs with compound capitula borne on erect, unbranched scapes. The capitula are hemispherical to spherical heads of tiny flowers. Most species are perennial; one species is recorded as an annual (Craspedia haplorrhiza). The leaves have considerable variation in form, ranging in colour from white to green, and are often covered in fine hairs.

Species of Craspedia are found in a wide range of habitats from coastal to alpine and are generally plants of open areas, sometimes ruderal. Observations of some Australian species suggest they re-establish well after fire. In Australia Craspedia are commonly found growing in forest habitat, whereas in New Zealand they are generally excluded from closed Nothofagus forests. Craspedia species may occur in dense, widespread populations in mainland Australia, but generally not in New Zealand or Tasmania.
