CVU, DunT, EGL, GipP, Gold, GGr, HNF, HSF, OtP, Strz, VVP. Endemic in Victoria. Extending west from Glengarry (near Traralgon) to Melbourne and north-west to Daylesford and Ararat. Collections of small-budded and -fruited swamp gums from east of Cavendish may be this taxon. Very small-fruited forms of the species occur in remnant stands in outer southeastern to northeastern Melbourne suburbs (e.g. Scoresby, Wantirna, Yan Yean).

A poorly known species whose distribution appears to have been much fragmented by the clearing of the natural habitat. It is distinguished from E. ovata by the completely rough bark and smaller leaves, buds and fruits. Fresh leaves steeped in hot water emit a bitter-almond (cyanic) odour, a reaction not observed in E. ovata.
