Callitris canescens is a plant from the family of the cypress family (Cupressaceae). It is native to southern Australia.
description
Callitris canescens 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 gray-green to blue-green leaves are 2 to 3 millimeters long and are rounded on the back.
The male cones are solitary, rarely in pairs on the branches and are egg-shaped with a length of up to 3 millimeters. The female cones stand individually or in groups on the branches and are shaped with a diameter of up to 2 centimeters wide-ovoid to flattened-spherical. Each cone contains six thick cone scales. The numerous black seeds have two or three wings which are up to 2 millimeters wide. Some of the seeds are only released from the cones years after they have ripened.
