Hibbertia pancerea

Hibbertia pancerea is a spreading shrub that typically grows to a height of 1.5 m (4 ft 11 in) with dense, scaly foliage. The leaves are elliptic, 15–25 mm (0.59–0.98 in) long and 10–15 mm (0.39–0.59 in) wide on a petiole 0.6–1.2 mm (0.024–0.047 in) long. The flowers are arranged singly in leaf axils, each flower on a peduncle 6–11 mm (0.24–0.43 in) long, with lance-shaped bracts 5.5–7.1 mm (0.22–0.28 in) long. The five sepals are joined at the base, the outer sepal lobes 7.3–8 mm (0.29–0.31 in) wide and the inner lobes 5.1–5.8 mm (0.20–0.23 in) wide. The five petals are broadly egg-shaped with the narrower end towards the base, yellow, 14–16 mm (0.55–0.63 in) long and there are 26 to 30 stamens arranged in bundles around the two carpels, each carpel with two ovules. Flowering has been observed in February and March.[2][3]

Hibbertia pancerea was first formally described in 2010 by Hellmut R. Toelken in the Journal of the Adelaide Botanic Gardens from specimens collected by David L. Jones in 1984 at Lightning Dreaming in Kakadu National Park.[2][4] The specific epithet (pancerea) means "with medieval mail of armour", referring to the large scales covering the plant.[2]

This hibbertia grows in shrubland and forest, amongst sandstone rocks and occurs on the top of the escarpment of the northern Arnhem Land plateau in Kakadu National Park.[2][3]

Hibbertia pancerea is classified as "vulnerable" under the Territory Parks and Wildlife Conservation Act 1976.[3]
