Callitris is a genus of coniferous trees in the Cupressaceae (cypress family). There come Fifteen mintage in the genus, of which Thirteen are indigen to Australia and the more ii (Hundred. neocaledonica, C. sulcata) indigen to New Caledonia. A virtually all widely utilized most common title is cypress-pine, the title divided per closely related genus Actinostrobus.

It is little to medium-moderate-sized trees or big shrubs, reaching 5-25 m tall (to Forty m around C. macleayana). A leaves are evergreen and scale-such as, except immature seedlings, inside which it is needle-prefer; in C. macleayana, needle-rather leaves come noticed mixed using shell leaves throughout a tree's life. A scales come intended withinside hexad rows along a branchlet, witharound alternating whorls of ternary (typically in whorls of quatern in C. macleayana).

A female cones beginside likewise invisible, maturing inside 18-20 months to One-Three cm hanker & wide, spherical to oviform (intense in C. macleayana), using sise imbrication, heavy, woody scales, intended witharound 2 whorls of tercet (typically Eight scales in C. macleayana). the cones remain closed on the trees for numerous years, opening sole fallowing existence scorched by a bushfire; this then releases a seeds to grow on the freshly vindicated burnt ground.

A genus is divided into 2 sections, using a untypical C. macleayana around sect. Octoclinis, & all the more mintage inside sect. Callitris. A bit of phytologist handle C. macleayana around the separate genus, when Octoclinis macleayana. C. macleayana is likewise distinct around occurring within rainforest in the east coast of Australia; the more metal money tons develop on dry web sites.

A nearest relatives of Callitris come Actinostrobus from southwest Western Australia, which differs in its cones with many radical whorls of little infertile scales, & Neocallitropsis from New Caledonia, distinct withwithin its needle-prefer leaves throughout a life of the plant (non good seedlings) & universally ordered in whorls of tetrad (non 3).
