GRAYLING, P.M. AND BROOKER, M.I.H.
Four new species from the informal Eucalyptus subgenus Symphyomyrtus Pryor & Johnson are described and illustrated. E. absita is a member of the E. series Porantheroideae (Maiden) Chippendale; E. balanites has similarities to E. decipiens Endl. in the E. series Micrantherae Benth. sensu Chippendale (1988); E. annuliformis is closely related to E. drummondii Benth. in the E. series Curviptera Maiden; and E. argutifolia is a member of the E. series Rufispermae Maiden. All four species are known only from small populations in coastal and sub-coastal south-western Australia.
