Brid, GipP, Glep, GGr, LoM, OtP, VVP, WaP, WPro, Wim. Also WA, SA. Apart from disjunct inland occurrences at Mt Arapiles and near Ouyen, apparently confined to coastal and near-coastal areas west from Wilsons Promontory.

Glabrous specimens sometimes appear amongst the more usual hairy plants (the latter formerly regarded as a distinct entity, Adriana klotzschii), but the two forms are otherwise identical and not worthy of taxonomic separation (Gross & Whalen 1996).
