Hibbertia incurvata

Hibbertia incurvata is a species of flowering plant in the family Dilleniaceae and is endemic to the Northern Territory. It is a spreading, woody shrub with scaly foliage, elliptic to lance-shaped leaves, and yellow flowers arranged in leaf axils with 28 to 35 stamens arranged in bundles around the two carpels.

Description
Hibbertia incurvata is a spreading shrub that typically grows to a height of up to 1.5 m and has stiff, woody branches. The leaves are elliptic to lance-shaped with the narrower end towards the base, 5.5–12 mm long and 2.5–4 mm wide and sessile or on a petiole up to 1.6 mm long. The flowers are arranged singly near the ends of shoots on a stiff peduncle 5–9 mm long, with lance-shaped bracts 2.8–4.6 mm long. The five sepals are joined at the base, the two outer sepal lobes lance-shaped 2.8–3.4 mm long and the inner lobes egg-shaped and slightly wider. The five petals are egg-shaped with the narrower end towards the base, yellow, 8.4–12.2 mm long and there are 28 to 35 stamens arranged in groups around the two carpels, each carpel with two ovules.

Taxonomy
Hibbertia incurvata was first formally described in 2010 by Hellmut R. Toelken in the Journal of the Adelaide Botanic Gardens from specimens collected near Maningrida in 2000. The specific epithet (incurvata) refers to the shape of the leaves.

Distribution and habitat
