Profile last updated: 24 Jul 2019


Shrub to 2.4 m high, root-suckering. Branchlets have a deep, firm covering of dense hairs. Leaves are stiff, broad-linear, 2 – 6 cm long, 0.25 – 0.4 cm wide, with a blunt apex and entire margins which are rolled under so that the leaf is convex, except for the midvein groove, on the upper surface. The upper surface is shiny and smooth or occasionally wrinkled, lower surface covered densely with brownish hairs; petiole 1 – 2 mm long. The flowers are small, 5-petalled, white or cream with mauve anthers. Individual inflorescences (groups of flowers) are up to about 10 cm long, usually with a few ascending branches, few-flowered, with a dense hairy covering.


Occurs near Patonga (Gosford LGA), and in Royal NP and on the Woronora Plateau (Sutherland and Campbelltown LGAs). There is also a record from near Glen Davis (Lithgow LGA).
