Mountain Grey Gum (Eucalyptus cypellocarpa) also known as the Mountain Gum, Monkey Gum or Spotted Mountain Grey Gum, is a straight, smooth barked forest tree. Often seen around 20 to 40 metres tall. But in moist protected gullies it may reach heights in excess of 60 metres tall.


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


This Eucalyptus is a small to a very tall tree. It has smooth bark with large unusually shaped sheets flaking off. Colours are anywhere from yellow to golden brown, to grey or white. This tree also has some of the longest leaves of this genus, up to 35 cm with a slight sickle shape. Flower buds are white and are shaped much like a cylinder with a cone-shaped tip. Fruit 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. Temperature distribution from -2°C to 31°C with an annual rainfall of 700 to 1300 mm.
