Common name: None

Description:
Erect, climbing or prostrate shrubs with rigid or wiry stellate-hairy stems and branches, to 2 m or rarely more high; leaves oblong to obovate, flat or with recurved margins, scattered or somewhat crowded, 3-15 X 2-8 mm, midrib narrow.

Flowers often 8-15 mm across, on filiform or somewhat rigid peduncles usually 5-15 mm long although broad-leafed plants may have subsessile flowers; bract at base of calyx 1, linear to linear-lanceolate; sepals 2.5-c. 5 mm long, densely or sparsely stellate-pubescent; petals yellow, deeply or shallowly notched, about as long as the sepals or up to half as long again; stamens 4-16, on one side of the carpels.

Carpels 2, pubescent, with 2 or 4 ovules in each.

	Hibbertia aspera.

Taxonomic notes: As defined here, H. aspera is an extremely variable species. The synonymy is based principally on Jacobs & Pickard (1981) Plants of New South Wales, and includes three of J. Black's (1952) taxa. It seems likely that some subdivision of this complex would be warranted at least at infraspecific level, but this must await a proper revision. H. billardieri F. Muell. is an illegitimate name and a synonym for H. empetrifolia (DC.)Hoogl., which is distinguished by Willis (1937) Handbook to plants in Victoria (under the name H. astrotricha (Sieber ex Sprengel)Wakef.) from H. aspera mainly in having smaller elliptical leaves bearing mainly simple hooked hairs. Willis considered that it occurred in S. Aust., but this was not confirmed by Jacobs & Pickard and no specimens identified as H. empetrifolia or H. astrotricha are known from S.Aust. Plants with subsessile flowers and/ or long hairs on the calyx are difficult to distinguish from H. sericea.
