A smooth-barked, slender, erect shrub growing to 2 m high (Wilson & Johnson 1989).

This species is restricted to a few small populations in and around Castlereagh NR, north-east of Penrith, NSW (Wilson & Johnson 1989). The total range of the species is approximately 36 km² (Matthes et al. 1996).

It was first collected in 1983 in Castlereagh SF (now Castlereagh NR). Ten other populations have been discovered since then (Matthes et al. 1996).

In 1996 there were 457 clumps of this species known (Matthes et al. 1996). A clump may represent one genetic individual (genet), or several genets (Nash & Matthes 1995). The largest population (405 clumps in 1996) has probably been reduced in size as a result of the expansion of an adjacent rubbish tip (Matthes et al. 1996).

This species is known to occur on Commonwealth land at the Holsworthy Military Area (Biosis Research 1997 in French et al. 2000).

This species grows on tertiary alluvial gravels, with yellow clayey subsoil and lateritic soil. These soils are low in fertility and are strongly to very strongly acidic. Rainfall in the area is lower than surrounding regions. The median annual rainfall is 803 mm (measured at the University of Western Sydney), with a summer peak (Wilson & Johnson 1989; Matthes et al. 1996).

It is found in the Castlereagh open woodland community, with Eucalyptus parramattensis, E. fibrosa, E. sclerophylla, Angophora bakeri and Melaleuca decora. Common associated understorey species include Melaleuca nodosa, Hakea dactyloides, H.sericea, Dillwynia tenuifolia, Micromyrtus minutiflora, Acacia elongata, A. brownei, Themeda australis and Xanthorrhoea minor (Matthes et al. 1996).

This species is dioecious or monoecious. Flowers are borne in Oct. It is long-lived and commonly exhibits a degree of vegetative spread. Root suckers appear up to 3 m from the parent plant. Suckers do not appear to be supported by a feeder root system, so the spread of the plant by this means is limited (Nash & Matthes 1995).

It is likely that genetic diversity is low, attributable to the small total population size, limited geographic range and the fact that regeneration is commonly by suckers (though see above). Only one site seems to demonstrate seedling recruitment. Since pollination is by wind, the distance between individuals may be important for successful pollination and seed set (Matthes et al.1996).

The species re-sprouts from the rootstock, but the minimum time required between fires for the species to survive is not known (Matthes et al. 1996).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
