Description

Hibbertia mulligana is a sub-shrub that typically grows to a height of up to 1 m (3 ft 3 in) with branchlets that are densely hairy when young. The leaves are narrow elliptic, 32–45 mm (1.3–1.8 in) long and 2.5–5.5 mm (0.098–0.217 in) wide on a petiole 1.5–2.5 mm (0.059–0.098 in) long. Both sides of the leaves, but especially the lower surface, are covered with star-shaped hairs and the edges of the leaves curve downwards. The flowers are 12–15 mm (0.47–0.59 in) wide and arranged singly in leaf axils on a thin peduncle 12–30 mm (0.47–1.18 in) long. The five sepals are densely hairy on the outside, joined at the base with the outer sepal lobes mostly 9–11 mm (0.35–0.43 in) long and the inner ones 6–7 mm (0.24–0.28 in) long. The five petals are yellow, egg-shaped with the narrower end towards the base, 8–10 mm (0.31–0.39 in) long with 70 to 74 stamens arranged around three densely hairy carpels.

Taxonomy

Hibbertia mulligana was first formally described in 1991 by Sally T. Reynolds in the journal Austrobaileya from specimens collected on Mount Mulligan in 1984. The specific epithet (mulligana) refers to the type location.
