A small erect, open sub-shrub 0.5-1 m high (SGAP 2000; NSW NPWS 2001a) and 1.5 m wide (SGAP 2000), with white or pale-pink flowers (Armstrong 2002).

Two populations are known from the Bells Creek area north of Araluen, on the eastern boundary of the Southern Tablelands of NSW (Armstrong 2002). A survey in September 1999 found 56 mature plants in total (26 adults and 33 seedlings in the upper population, and 30 adults and 9 seedlings in the lower population) (NSW NPWS 2001a). In February 2002, this population contained 90 plants that were over 20 cm in height (J.D. Briggs, pers. comm. in Armstrong 2002).

The two populations are approximately 100 m apart, separated by a 20 m high rockface and mainly on crown leasehold land owned by the Department of Land and Water Conservation but perhaps extending on to private land (NSW NPWS 2001a). The population above the rockface, covers only 50 m² (Briggs & Leigh 1990). Due to the specific habitat required, it is unlikely that the species will ever expand (NSW NPWS 2001a).

Prior to the rediscovery of this species at Bells Creek in the 1980s, it had not been collected for nearly 100 years and was considered extinct (Briggs & Leigh 1990; Meredith & Richardson 1990). Further surveys have not located any additional populations (Briggs & Leigh 1990; NSW NPWS 2001a).

Historical records, while imprecise, suggest that early collections were made in the general vicinity of the known population and from a disjunct occurrence on the Murrumbidgee River (Briggs & Leigh 1990). However, notes associated with these collections suggest that the plant was extremely rare even at that time (NSW NPWS 2001a).

The only known population occurs on the steep, rocky upper slope of a hillside that faces north-north-west and overlooks a deep valley. The species grows in shallow sandy to gravelly loam, amongst granite boulders ((Briggs & Leigh 1990; NSW NPWS 2001a; Armstrong 2002).

The shrub community at this site also includes Acacia mearnsii, Dodonaea viscosa, Correa reflexa, Ficus rubiginosa, Notelaea venosa, Plectranthus parviflorus and Poa sieberiana. Low open forest dominated by stunted Eucalyptus maidenii grows nearby (Briggs & Leigh 1990; Armstrong 2002).

Flowers are borne from Aug.- Oct. (Harden 2002; SGAP 2000; NSW NPWS 2001a). Mature plants flower prolifically and the level of fruit set is high. The fruits develop rapidly and almost all seed is shed by the end of Dec. Flowers are almost certainly pollinated by flying insects (NSW NPWS 2001a).

Seed production, seed germination and seedling establishment do not appear to be limiting factors. The population is strongly bimodal consisting of very young seedlings or mature plants (Harden 2002; NSW NPWS 2001a; Armstrong 2002).

The longevity of wild plants seems to be 20-30 years: cultivated specimens have a shorter lifespan (NSW NPWS 2001a).

The response of the species to fire is unknown, but basal shooting and/or suckering have not been noted (NSW NPWS 2001a).

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.
