Key's Boronia is an open shrub to 2 m high with deep rose-pink or white flowers (Stanley & Ross 1983; Leigh et al. 1984; Leigh & Briggs 1992; Duretto 1999b).

This species has a restricted distribution in the Noosa Plains area, between Kin Kin and Lake Cootharaba, east of Gympie, Qld (Stanley & Ross 1983; Leigh et al. 1984; Leigh & Briggs 1992; Qld CRA/RFA Steering Committee 1997; Duretto 1999b). More specifically, it occurs in an area of approximately 150 ha on the lower Kin Kin Ck and upper Noosa R. basins, east of the private property of Tarangau (QDNR 2000).

The species had not been seen for 62 years until it was rediscovered in 1971 (Stanley & Ross 1983; Leigh et al. 1984; Leigh & Briggs 1992; Qld CRA/RFA Steering Committee 1997; Duretto 1999b).

There are 15 known populations within a 5 km radius. The largest concentration of plants occurs within a 2 km radius. Four small populations occur in Como SF (SF 1004), eight in Great Sandy NP (Cooloola section) and three on freehold land. About a third of the known habitat and two of the largest populations are on private land. One state forest population is in a Scientific Area (SA 3) (QDNR 2000).

This species is found in lowland areas up to 20 m asl, where it is usually scattered through the understorey (QDNR 2000). The climate is subtropical, with a mean annual rainfall of 1600 mm. The sandy soil is rich in humus, with the water table 0.6-0.9 m below the surface (Leigh et al. 1984).

It is found in mixed eucalypt and Brushbox Lophostemon confertus woodland, ranging to open forest, and varying in height from 8-35 m. The taller habitats are dominated by Eucalyptus grandis and E. intermedia with well developed vineforest understorey. Species in the shorter habitats include E. intermedia, E. resinifera, E. robusta, Leptospermum flavescens, L. whiteii and Elaeocarpus reticulatus (Leigh et al. 1984; Leigh & Briggs 1992; Qld CRA/RFA Steering Committee 1997). Other associated species include Eucalyptus acmenoides, E. gummifera (Leigh et al. 1984) and Agathis (Duretto 1999b); with understoreys of Acronychia laevis, Phebalium woombye, Syzygium coolminianum, Baeckia virgata and B. stenophylla (Leigh et al. 1984).

Flowering occurs Apr-Dec, but is most profuse in early spring. Fruiting occurs July-Dec. (Duretto 1999b).

Periodic fire is required for substantial regeneration (Stanley & Ross 1983; Leigh et al. 1984; Leigh & Briggs 1992; QDNR 2000). Plants are killed by fire but regenerate from seed. The species also germinates well following soil disturbance (QDNR 2000).

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.
