GipP, EGL, EGU. Also NSW. Vary rare in Victoria, with 2 disjunct occurrences, near Providence Ponds and eastern slopes of the Howe Range. Mostly in heath and dry sclerophyll forest, usually on sand or sandy soils. .
Older plants usually have a substantial lignotuber or rootstock. The small Providence Ponds population has diminished due to clearing and burning in recent decades, and the species is now regarded as endangered in Victoria.
