Description

Hibbertia glabrisepala is an erect to sprawling shrub that typically grows to a height of 0.45–1.0 m (1 ft 6 in – 3 ft 3 in) with mostly glabrous foliage. The leaves are linear to narrow oblong, 9–20 mm (0.35–0.79 in) long and 1–3 mm (0.039–0.118 in) wide with the edges turned downwards. The flowers are 15–20 mm (0.59–0.79 in) wide, borne singly or in small groups on the ends of short side shoots and are sessile with two or three more or less round bracts 3–5 mm (0.12–0.20 in) long. The five sepals are joined at the base, egg-shaped to elliptic, 6–10.5 mm (0.24–0.41 in) long and more or less glabrous. The five petals are bright yellow, egg-shaped with the narrower end towards the base, 6–11 mm (0.24–0.43 in) long with a shallow notch at the tip. There are fifteen stamens arranged in three groups around the five carpels, each carpel containing a single ovule. Flowering occurs from May to October. [2] [3]

Taxonomy

Hibbertia glabrisepala was first formally described in 2002 by Judy Wheeler in the journal Nuytsia from specimens she collected near Kalbarri in 1984. [4] The specific epithet (glabrisepala) refers to the glabrous sepals. [2]

Distribution and habitat

This hibbertia grows in sandy soil in heath and mallee in the Avon Wheatbelt, Geraldton Sandplains and Yalgoo biogeographic regions of south-western Western Australia. [2] [3]

Conservation status

Hibbertia glabrisepala is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. [3]
