Distinguished from E. dumosa by the predominantly glossy green leaves and more or less sessile buds and fruit. Eucalyptus phenax has been incorrectly known as E. anceps, a synonym of the South and Western Australian species, E. rugosa.
Thought to hybridise with E. wimmerensis at the southern edge of its range (see E. x macmahonii)
