Description edit
Hibbertia papillata is an erect shrub that typically grows to a height of 30–40 cm (12–16 in), its young branchlets moderately covered with minute, star-shaped hairs. The leaves are hairy, more or less crowded, linear, 6–12 mm (0.24–0.47 in) long, about 1 mm (0.039 in) wide on a petiole 0.5–1 mm (0.020–0.039 in) long with the edges rolled under and covering most of the lower surface. The flowers are arranged singly in leaf axils near the ends of branches on pedicels 3–8 mm (0.12–0.31 in) long with narrow triangular bracts 1.5–4 mm (0.059–0.157 in) long at the base of the sepals. The five sepals are egg-shaped, 3.5–6 mm (0.14–0.24 in) long with star-shaped hairs on the outside. The five petals are yellow, egg-shaped with the narrower end towards the base and 4.0–7.5 mm (0.16–0.30 in) long with a small notch at the tip. There are usually ten stamens arranged on one side of, and curving over two hairy carpels that each contain two ovules. Flowering occurs from September to October.[2][3]
Taxonomy edit
Hibbertia papillata was first formally described in 2004 by Judith R. Wheeler in the journal Nuytsia from specimens she collected on the south-east slopes of East Mount Barren in 1986.[2][4] The specific epithet (papillata) refers to the minute pimples on the upper surface of the leaves.[2]
Distribution and habitat edit
This hibbertia is only known from the Fitzgerald River National Park where it grows in low heath on ridges and slopes.[2][5]
Conservation status edit
Hibbertia papillata is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife[5] meaning that it is poorly known and from only one or a few locations.[6]
