About Philotheca hispidula (Spreng.) Paul G.Wilson
Philotheca hispidula is a shrub that usually reaches a height of around 1 metre (3 feet 3 inches). Its branchlets are slightly glandular-warty and covered in fine bristles. The leaves are narrow egg-shaped to narrow wedge-shaped, with the narrower end at the base, and measure 10–20 millimetres long and 3–4 millimetres wide. Flowers are most often borne singly in leaf axils, on a finely bristly peduncle that is 1–15 millimetres long, with a 3–5 millimetre long pedicel. This species has five semi-circular sepals with fleshy centres, each about 1 millimetre long, and five broadly elliptical white or pale pink petals around 6.5 millimetres long, each with a glandular keel. Its ten stamens are slightly hairy. Flowering takes place in spring, and the fruit is about 7 millimetres long with a 3-millimetre long beak. Philotheca hispidula grows in forest on sandstone in the Blue Mountains and the Sydney region.
