Flowering in South Australia is recorded as being between November and March, while in the Grampians in Victoria it extends from September to April.

[5][6] The species was formally described in 1838 by English botanist John Lindley in Three Expeditions into the Interior of Eastern Australia based on plant material collected from Mount William in the Grampians by Thomas Mitchell.

[9] In South Australia, small populations are found at locations such as Carpenter Rocks, Bucks Lake Game Reserve and West Dairy Range.

In Victoria the species is found in the Grampians region and northwards to the Little Desert as well as near the south coast at Kentbruck Heath near Portland.

[1] A number of naturally occurring forms have been brought into cultivation from locations including Carpenter Rocks, Cooack, Halls Gap, Kenbruck Heath, Lake Wartook, Little Desert, Mount William and Serra Road.
