description
Callitris muelleri grows as an evergreen shrub or tree that can reach heights of up to 6 meters. The branches go up straight from the trunk.
The green to blue-green leaves are 4 to 10 millimeters long and the back of the leaves is conspicuously keeled.
The male cones stand together in groups and are egg-shaped to obovate-shaped with a length of up to 3 millimeters. The female cones standing singly or in small groups on the branches are flattened-spherical in shape with a diameter of 2 to 3 centimeters. Each cone contains six thick cone scales and numerous seeds. The seeds can remain in the cones for several years after ripening before they are released and the cones fall from the branches. The dark brown seeds are about 2 to 4 millimeters in size and have two or three wings.
