The Barbalin Boronia is a shrub up to 1m with pink flowers (Duretto 1999b).

This species is restricted to part of the Central Wheatbelt district, west of Perth, WA. It has a range of around 125 km, from south of Trayning to Mt Marshall, north of Beacon in the Merredin district (Mollemans et al. 1993; Brown et al. 1998).

This species was once thought to be extinct (Hopper et al. 1990), but is now known from several populations. Some of these are in small reserves, eg Karroun Hill NR, WA (Duretto 1999b). In 1993, three populations (1, 2 & 5 below) had senescing plants and appeared to be in decline (Mollemans et al. 1993).

Details of populations as in Mollemans et al. (1993):

B. adamsiana is closely related to Boronia ternata (Mollemans et al. 1993; Brown et al. 1998)

This species grows in heath or scrub heath on yellow sand, near granite outcrops (Hopper et al. 1990; Mollemans et al. 1993; Brown et al. 1998). The largest population grows in association with Eucalyptus synandra. The four populations on private properties are on areas cleared with chains and left to regenerate (Mollemans et al. 1993).

Flowering occurs from June to Sept. (Hopper et al. 1990; Mollemans et al. 1993; Brown et al. 1998). Fruiting continues to Oct. (Duretto 1999b).

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.
