Perennial herbs with glandular and/or cottony hairs. Leaves cauline, sessile, alternate, entire.

Florets numerous, bisexual or the outer female, yellow or white; corolla deeply 5-lobed (3 or 4 in female); anthers tailed at base; style branches linear with truncate to rounded apices. Cypselas terete or somewhat compressed, with 2–4 ribs, not beaked, smooth or sparsely glandular with a few minute unicellular hairs. Pappus 1-seriate, of basally connate barbellate bristles, plumose or subplumose at apex, persistent, sometimes fewer or absent in female florets.

An Australian endemic genus of 10 species.

All Victorian species previously placed in Ixiolaena as well as one species previously placed in Leptorhynchos, L. gatesii, are now placed in Leiocarpa. Leiocarpa is distinguished from Ixiolaena by glabrous cypselas with persistent pappus. Ixiolaena is now a monotypic genus restricted to Western Australia.
