Hibbertia demissa


Hibbertia demissa is a species of flowering plant in the family Dilleniaceae and is endemic to a restricted area of New South Wales. It is a low-lying shrublet with small elliptic leaves and single yellow flowers arranged on the ends of branchlets, with nine to twelve stamens arranged around three carpels.

Description

Hibbertia demissa is a shrublet that typically grows up to high with wiry, low-lying branches. The leaves are oblong to elliptic, long and wide on a petiole up to long. The flowers are sessile, arranged singly on the ends of branches with lance-shaped bracts about long. The five sepals are joined at the base, the two outer sepal lobes long and the inner lobes long. The five petals are broadly egg-shaped with the narrower end towards the base, yellow and about long. There are nine to twelve stamens arranged around the three hairy carpels, each carpel with four ovules. Flowering has been observed in October.

Taxonomy

Hibbertia demissa was first formally described in 2013 by Hellmut R. Toelken in the Journal of the Adelaide Botanic Gardens from specimens collected "near the top of the range near Backwater" in 1929. The specific epithet means "low and humble", referring to the habit of this species.

Distribution and habitat

This hibbertia grows in sandy soil over granite in forest on the Northern Tablelands of New South Wales.
