Geographical distribution
The Cupressaceae family (16 genera and 140 species) is widely distributed throughout the world. The Cypresses are composed of 6 genera, and all are rather closely related: Cupressus (Cypresses), Juniperus (Junipers), Thuja (White cedars or Arborvitae), Libocedrus (Incense cedar), Chamaecyparis, and Callitris. They are distinguished by their small opposite or whorled leaves, which are usually scale-like, and their small pistillate cones with few scales. The pollen grains of this group are extremely uniform and spheroidal in form.
