Fruit sessile or shortly pedicellate, cylindric or barrel-shaped, to 1.2 cm long, 0.9 cm diam.; disc vertically descending; valves 3 or 4, rim level or enclosed; seed brown, pyramidal to cuboid with toothed edges, hilum terminal.

The only native representative in Victoria of series Transversae, it has been traditionally classified with the eastern blue gums (subseries Leptocarpae) and in a recent study was reduced to a subspecies of E. saligna (Passioura & Ash 1993). However, on bark characters it belongs to the related red mahoganies (subseries Annulares) and its natural affinities remain unresolved. Some mostly smooth-barked E. botryoides in the Cann Valley approach E. saligna (see note under that species).

A small number of scattered white gums occurring on the Bool-Poole Peninsula in the Gippsalnd Lakes were thought to be hybrids between E. botryoides and E. tereticornis. Seedling trials suggest they may represent a relic species related to E. deanei Maiden, a grey gum from coastal Central New South Wales (K. Rule pers. comm.).
