Description: Shrubs 1–4 m tall; hairs on young stems dense, finely acicular, not or only sporadically gland-tipped.
Mature leaves 20–35mm long, 0.7–1.0mm wide, with hairs on upper surface moderately dense, coarse, conical and not gland-tipped; hairs on undersurface of midrib similar, less dense, and (at least when young) hidden by cottony hairs; undersurface of lamina with dense cottony hairs, subsessile globular hairs and very occasional long fine gland-tipped hairs.
Flowerheads with 9 or 10 per florets.
Flowering: Flowers December to February.
Distribution and occurrence: Known only from the Goonoowigal Bushland Reserve approximately 6 kmS of Inverell, in the NorthWestern Slopes district of New South Wales.
Found in sandy soil on granite, from steep slopes to rock platforms, usually in Eucalyptus forest (E. caleyi, E. dealbata, E. prava), with Macrozamia, Callitris endlicheri, Leptospermum brevipes, Poa and Acacia, but sometimes in heathland with Homoranthus flavescens and also in seepage areas with a broad-leaved sedge.
NSW subdivisions: NWS
Within the reserve populations are apparently scattered but the plant can be locally very abundant. However, the total population size is unlikely to exceed a few hundred plants. Altitudes range from 625 to 780 m. The plants have a ‘curry’ or slightly resinous odour.
