Eucalyptus punctata, commonly known as grey gum, is a small to medium-sized tree that is endemic to eastern Australia. It has smooth grey bark that is shed in patches, lance-shaped, curved or egg-shaped adult leaves flower buds in groups of seven, white flowers and hemispherical or cup-shaped fruit. Its leaves are one of the favoured foods of the koala. Description Eucalyptus punctata is a tree that typically grows to a height of and forms a lignotuber. It has smooth grey, brown or cream-coloured bark that is shed in patches. Young plants and coppice regrowth have dull green leaves that are paler on the lower surface, egg-shaped to lance-shaped, long and wide and petiolate. Adult leaves are glossy dark green, paler on the lower surface, lance-shaped or curved to egg-shaped, long and wide tapering to a petiole long. The flower buds are arranged in leaf axils in groups of seven on an unbranched peduncle long, the individual buds on pedicels long. Mature buds are oval, long and wide with a conical to rounded operculum. Flowering occurs from December to March and the flowers are white. The fruit is a woody, cup-shaped or hemispherical capsule long and wide. Taxonomy Eucalyptus punctata was first formally described in 1828 by Swiss naturalist Augustin Pyramus de Candolle in his book Prodromus Systematis Naturalis Regni Vegetabilis. The specifici epithet (punctata) is from the Latin adjective punctatus meaning "spotted" and refers to the oil glands, which give the leaves a dotted appearance. It is one a group of related species known collectively as large-fruited grey gums found in eastern Australia, the others being E. longirostrata from eastern Queensland, E. biturbinata from the New England region, and E. canaliculata from the vicinity of Gloucester and Dungog in central-northern New South Wales. Distribution and habitat Grey gum occurs through the ranges and near coastal areas from near Gympie in Queensland to near Nowra in New South Wales, most commonly on transition zone soil types between sandstone and shale. It grows in tall open sclerophyll forest, associated with such species as red bloodwood (Corymbia gummifera), pink bloodwood (C. intermedia), spotted gum (C. maculata), white stringybark (E. globoidea), Sydney peppermint (E. piperita), blackbutt (E. pilularis), yellow box (E. melliodora), mountain grey gum (E. cypellocarpa), narrow-leaved ironbark (E. crebra), grey ironbark (E. paniculata), broad-leaved white mahogany (E. umbra), white mahogany (E. acmenoides), and apples (Angophora species).
