Description

Hibbertia sulcata is a shrub that typically grows to a height of up to 20 cm (7.9 in) and has wiry branches and scaly foliage. The leaves are linear, mostly 20–35 mm (0.79–1.38 in) long, 1.2–1.6 mm (0.047–0.063 in) wide and more or less sessile. The flowers are arranged singly or in pairs in leaf axils on a thread-like peduncle 3.3–5.7 mm (0.13–0.22 in) long, with linear bracts about 1 mm (0.039 in) long at the base. The five sepals are joined at the base, the two outer sepal lobes 2–2.5 mm (0.079–0.098 in) long and 2 mm (0.079 in) wide, and the inner lobes longer and broader. The five petals are wedge-shaped with two lobes, yellow, 4.2–5.6 mm (0.17–0.22 in) long and there are 22 to 24 stamens arranged around the two densely scaly carpels, each carpel with two ovules. [2]

Distribution

This hibbertia is only known from a single specimen collected from the Gudjekbinj outstation. [2]
