Xanthosia stellata, commonly known as star xanthosia,[2] is a species of flowering plant in the family Apiaceae and is endemic to eastern Australia.

Xanthosia stellata is an erect or ascending subshrub that typically grows to a height of 20 cm (7.9 in) and has star-shaped hairs on its stems and leaves.

There are yellow, later reddish petal-like involucral bracts 4–6 mm (0.16–0.24 in) long at the base of the peduncles.

[4] This species of xanthosia grows in forest in the Blue Mountains and Southern Highland of New South Wales, and in Queensland.
