Terrestrial. regenerating bush and scrub near planted trees and hedgerows.
Medium sized tree to about 36 metres. Has distinctive fluted trunk when mature, bark is thick, reddish brown beneath often becoming whitish on the surface. Adult foliage comprises many small dark green scales closely appressed to the branchlets, but not flattened. Juvenile foliage more needle like, and not appressed. Male cones up to about 3 mm long, yellow and knobbly arising on the tips of the branches. Female cone are also terminal, rosette-like at first, becoming a rounded brown cone with 8-14 scales when mature. Usually 10-20 small seeds per cone scale.
The scales closely appressed on mature plants, but stems not becoming flattened. There are several Hesperocyparis and Cupressus species in cultivation in New Zealand but H. macrocarpa is by far the most common, and can be identified by the blunt leaves lacking resin glands, and the shining brown mature cones.
