GipP, HSF, Strz, VAlp, *CVU, *EGL, *Gold, *OtP, *VVP, *WaP. Endemic to Victoria.. Confined to eastern Victoria from the upper Macalister River area near Mt Howitt south to near Yarram and east to near Tabberabbera. Grows in moist forest. Widely cultivated and naturalising in some areas (e.g. Daylesford, Greater Melbourne, Dandenong Ranges etc.).

A member of the A. verniciflua complex. Putative hybrids occur between A. howittii and A. stictophylla where the former is naturalised at Ringwood, and near Coleraine apparent hybrids exist between A. howittii and the rare, locally endemic A. exudans.

The species is widely planted as an ornamental, especially for its pendulous foliage and profuse, perfumed heads. Phyllodes are sometimes to 3.5 cm long in cultivation.
