Cupressaceae is a widely distributed conifer family, with a near-global range in all continents except for Antarctica, stretching from 70°N in arctic Norway (Juniperus communis) [3] to 55°S in southernmost Chile (Pilgerodendron uviferum), further south than any other conifer species. [4] Juniperus indica reaches 4930 m altitude in Tibet. [5]

[7] The foliage grows in dense, dark green sprays. The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattened) shoots.
