Description

Hibbertia scabra is a shrub that typically grows to a height of 20 m (66 ft) and has its foliage covered with scales and rosette-like hairs. The leaves are linear to narrow elliptic, mostly 9.5–18 mm (0.37–0.71 in) long and 1–2 mm (0.039–0.079 in) wide on a petiole up to 1.2 mm (0.047 in) long. The flowers are arranged singly near the ends of branches, each flower on a wiry peduncle 12.8–22.5 mm (0.50–0.89 in) long, with linear bracts 2.4–2.6 mm (0.094–0.102 in) long at the base. The five sepals are joined at the base, the two outer sepal lobes 5.4–8.5 mm (0.21–0.33 in) long and 2.2–3.3 mm (0.087–0.130 in) wide, and the inner lobes slightly shorter but broader. The five petals are egg-shaped with the narrower end towards the base, yellow, 5.5–11.6 mm (0.22–0.46 in) long and there are about fifty stamens arranged around two densely scaly carpels, each carpel with two ovules. Flowering occurs from March to April. [2] [3]

Distribution and habitat

This hibbertia grows in woodland in a few locations in northern Arnhem Land in the Northern Territory. [2] [3]

Conservation status

Hibbertia scabra is classified as "near threatened" under the Territory Parks and Wildlife Conservation Act 1976 . [3]
