VVP, GipP, Gold, CVU. Virtually restricted to the Brisbane Ranges area between c. Steiglitz and Anakie, and to the southern end of the Werribee Gorge area. Olde & Marriott (1995) make reference to an occurrence of a single plant above the Moorabool River gorge near Egerton, but there appear to be no herbarium specimens to substantiate this record. There is also an undated historic collection from 'Station Peak' in the You Yangs, but it is unclear whether the plant was actually collected there. Grows in dry sclerophyll forest in rocky situations with sandy or quartzitic-clay soils.
The sericeous branchlet indumentum, and the open sericeous leaf undersurface are useful diagnostic characters in contrast to some closely related species.
