A widespread species recorded from the South Australian border to as far east as Briagolong and the Beechworth area. Occupies a diversity of habitats, e.g. Eucalyptus tereticornis woodland at Briagolong, and saltmarsh with Melaleuca halmaturorum at Jilpanger.
Willis (1973) followed Davis (1948) in recognising 2 varieties within the species and in referring most Victorian collections of B. perpusilla to var. tenella, with only some Victorian specimens considered to be 'closely approaching' var. perpusilla. As delimited here only 1 taxon occurs in Victoria and South Australia (other taxa occur in Western Australia). Furthermore, the type specimens of both var. perpusilla and var. tenella are of the same taxon.
