Apart from a few isolated sites near Melbourne (Long Forest near Bacchus Marsh, Jacksons Creek between Diggers Rest and Keilor), confined in Victoria to the north-west where widespread and sometimes locally common. Grows predominantly in mallee, often on gypseous sands.
Specimens with more or less campanulate fruit with tapering sides and obliquely truncate apices have been collected in Victoria. These plants may require recognition at some taxonomic level.
