Genus Craspedia Family Asteraceae

Description: Annual and perennial herbs usually with a basal rosette; roots many, thick woolly and spreading or with a taproot.

Leaves alternate, in a basal rosette and sometimes cauline, margins entire, mostly stem-clasping, decreasing in size up stems.

Inflorescence a globose or hemispherical compound head on a scape; compound head of 20–125 stalked or sessile partial heads on a globose or conical general receptacle, common involucre of bracts usually similar to uppermost leaves; partial heads each subtended by a ± herbaceous bract and with 5–10 colourless involucral bracts, each partial head with 4–12 florets on a common receptacle; florets subtended by a scale similar to the bracts of the partial head, florets tubular, bisexual, 5-merous. Anthers tailed at the base with triangular apical appendages. Style branches flattened, linear-oblong, truncate, papillose with fimbriate apices.

Achenes obovoid, silky with bifid hairs; pappus a single ring of colourless plumose pappus bristles, fused for varying lengths at base.

Distribution and occurrence: World: 21–43 species, New Zealand, Australia. Australia: 13 species (endemic), Qld, N.S.W., Vic., Tas.

C. species G in Jacobs & Pickard (1981) [C. species B in Thompson (1981) and C. species B in Costin et al. (1979)] is now regarded as representing hybrids of various alpine species.
