Tall, and always remarkably erect, eventually large, dioecious evergreen, long-lived, resiniferous trees. When young and often throughout life they have very strongly whorled and stout, more or less level to typically somewhat ascending branch systems, usually with upturning tips, with the lower branch whorls either retained or eventually shed to leave clean trunks which sometimes bear further foliar episodes of crown reiteration from middle to higher portions of the trunk. Tree crowns generally highly symmetric.
