MuM, NIS, VRiv. Also WA, SA. Known from only 2 collections in the north-central part of the state (Quambatook, Terrick Terrick) where growing in Callitris-dominated woodland.

The Victorian collections are significantly disjunct from the nearest occurrences in S.A. near the Victorian border. Its absence from N.S.W. is surprising.
