Eucalyptus cypellocarpa, commonly known as mountain grey gum, mountain gum, monkey gum or spotted mountain grey gum, is a straight, smooth-barked forest tree.


Eucalyptus cypellocarpa was described by the Australian botanist Lawrie Johnson in 1962.[1]


This Eucalyptus is a small to a very tall tree. Often seen around 20–40 m in height, in moist protected gullies it may reach heights in excess of 60 m. It has smooth bark with large, unusually shaped, sheets flaking off. Colours are anywhere from yellow and golden brown, to grey and white. The tree has some of the longest leaves of the genus, up to 35 cm with a slight sickle shape. Flower buds are white and cylindrical with a cone-shaped tip. The fruits are barrel-shaped, 1 cm long by 0.9 cm diameter, with a sunken disk.

Distribution and habitat[edit]

Mountain gum tends to grow in wet sclerophyll forest, in gullies and on mid-altitude hillsides. From 30.25 to 39 degrees south, mountain gum grows from near sea level altitudes to 1200 m and grows in cool to warm, humid to sub-humid environments with a temperature distribution of -2 °C to 31 °C with an annual rainfall of 700 to 1300 mm.
