Description

Eucalyptus alaticaulis is a tree or mallee growing to a height of about 20 m (70 ft) with rough, grey, fibrous bark on the lower part of the trunk and main stems. The leaves on young plants are arranged in opposite pairs, broadly lance-shaped to egg-shaped, up to 140 mm (6 in) long, 90 mm (4 in) wide and glossy green but a lighter shade on the lower side. The adult leaves are lance-shaped, 120–300 mm (4.7–12 in) long and mostly 20–45 mm (0.8–2 in) wide and have a longer petiole than the juvenile leaves. They are the same colour on both surfaces. The flower buds are arranged in groups of seven on a flattened peduncle up to 24 mm (0.9 in) long, the individual buds on a short pedicel. The buds are more or less cylindrical with a conical operculum and the flowers are white. The fruit is cylindrical to oval, about 10 mm (0.4 in) long and 9 mm (0.4 in) wide.[4]

This species was previously included in E. cypellocarpa but is shorter, has persistent bark and broader juvenile leaves.[4]

Taxonomy

Eucalyptus alaticaulis was first formally described in 1987 by R.J.Watson and Pauline Y. Ladiges and the description was published in the journal Brunonia.[2] The specific epithet (alaticaulis) is derived from the Latin words alatus meaning "winged",[5]: 858  and caulis meaning "stem" or "stalk".[5]: 750 

Distribution and habitat

The Grampians grey-gum is restricted to dry rocky slopes in the Grampian Ranges.[4]
