Verrucosa Callitris is a plant from the family of the cypress family (Cupressaceae). It is native to southeastern Australia.
description
Callitris verrucosa grows as an evergreen shrub or small tree that can reach heights of up to 8 meters. Usually several tribes are formed. The branches go up straight from the trunk.
The green to gray-green leaves are 2 to 4 millimeters long. Their back is rounded.
The male cones are in groups on the branches and are cylindrical in shape with a length of up to 5 millimeters. The egg-shaped to spherical female cones stand individually or in groups, have a stem and are 2 to 2.5 centimeters thick. Each cone consists of six thick, finely warty cone scales and carries numerous seeds. After ripening, they remain on the branches for several years before they release the seeds and fall. The dark brown seeds are about 4 millimeters in size and have two or three wings.
The number of chromosomes is 2n = 22.
