A lemon-scented, spreading, prostrate shrub up to 15 cm high (Armstrong 2002; Harden 2002) with conspicuous pale pink to white flowers c. 8 mm in diameter (Armstrong 2002).

The species is restricted to two populations in the Countegany district of the Southern Tablelands of NSW and four populations in East Gippsland, Victoria (Briggs & Leigh 1990: Armstrong 2002).

In NSW, the two populations are in the Kybean Range, east of Cooma,. The first, of about 150 plants, occupies an area of c. 15 ha 5 km east of Numeralla and the other, of 32 plants, covers about 2 ha 2 km north-west of Kybean Trig. (Briggs & Leigh 1990; Armstrong 2002). The first site is on crown land whereas site 2 straddles the boundary of two private properties. In 1986, all plants at both sites had been browsed and no seedlings were found (Briggs & Leigh 1990).The population near Numeralla was monitored by the NSW NPWS in August 1998 following a wildfire through the area in the previous summer. It consisted of 154 mature plants that were vigorously resprouting from their rootstocks and 109 seedlings (J. Briggs, pers. comm. in Armstrong 2002). In 2002, the total number of individual plants in NSW was estimated as fewer than 600 (NSW Scientific Committee 2002h).

The four Victorian populations were discovered in 1988 (Briggs & Leigh 1990) and contained a total of 400 plants, occupying around 2 ha, c. 6 km north-west of Mt Cobberas No. 2, near Benambra in East Gippsland (Briggs & Leigh 1990). However, more recently the Victorian population was reported to consist of 40 plants (Victorian Workshop 2000, pers. comm.).

Whilst neither of the NSW populations occurs within a reserve, the species is conserved in Victoria in the Cobberas-Tingaringy section of Alpine NP (Briggs & Leigh 1996).

This species was referred to as Zieria sp. 2 (sp. B) in Briggs & Leigh (1990). It has been misidentified as Z. aspalathoides, a widespread species that occurs further west in NSW and Vic. (Armstrong 2002).

The NSW populations are on moderately steep, generally north to south-west facing slopes near small ephemeral creeks. The soils are shallow gravelly or sandy loams overlying decomposed granite or metamorphosed sediments. The habitat is apparently similar in Victoria but the substrate is ignimbrite (Snowy R Volcanics) and Buchan Limestones (Briggs & Leigh 1990; Armstrong 2002).

The vegetation is low eucalypt woodland with a shrub understorey (Briggs & Leigh 1990; Armstrong 2002). Associated vegetation in NSW includes Eucalyptus mannifera, E. macrorhyncha, E. dives, Allocasuarina nana, Banksia canei, Brachyloma daphnoides, Monotoca scoparia, Leucopogon attenuatus, L. fraseri, L. fletcheri, L. pilibundus, Platysace lanceolata, Pultenaea procumbens, Hibbertia obtusifolia, Bossiaea foliosa, Lomandra longifolia, Olearia iodochroa, Poa sp. and Acacia spp. (Briggs & Leigh 1990). In Victoria the species grows in Eucalyptus rubida, E. dives open forest (Armstrong 2002).

Flowers occur in winter and spring (SGAP 2000), late winter to summer (Armstrong 2002; Harden 2002) or Nov.-Dec. (Briggs & Leigh 1990), with fruiting specimens observed early spring to autumn (Armstrong 2002). Flowering and seeding continued despite heavy browsing (Briggs & Leigh 1990).

The species spreads vegetatively from rhizomes. Following a wildfire near Numeralla in 1998, many plants vigorously resprouted from their rootstocks. Stem layering has also been observed in plants at this site (Armstrong 2002).

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.
