Callitris rhomboidea is a plant belonging to the family of the cypress family ( Cupressaceae ). It is native to southeastern Australia.
Description
Callitris rhomboidea grows as a evergreen tree that can reach heights of growth of 9-15 meters and diameter at breast height 29-44 centimeters. The narrow and dense branches go straight or upright from the trunk. The bark is not cracked.
The tight-fitting on the branches leaves are light to blue- green, 2 to 3 millimeters long and its back is keeled striking.
The male cones are available individually or in groups on the branches and are at a length of up to 2 mm oval shaped. The egg-shaped to flattened - spherical female cones are usually in groups, are gray -brown to maturity and are 0.8 to 2 inches thick. Each pin consists of six thick, diamond-shaped cone scales and bears numerous seeds. They remain after maturity a few years on the branches before they laid off and drop the seeds. The dark brown seeds are rounded with a diameter of about 1 mm and have two or three blades.
