Distribution en:

Description en: Genus of 2 species of upright, conical, monoecious, deciduous or semi-evergreen, coniferous trees found in swampy forest or by river margins from S.E. USA to Guatemala. The shoots are of 2 types: deciduous (without buds), which fall in autumn, and persistent (with buds), from which only the leaves fall. The narrowly lance-shaped or linear leaves are arranged alternately, radially, or in 2 ranks. Male cones occur in groups; female cones are scattered. They are late to come into leaf and to assume the spectacular autumn colours for which they are renowned. Grow as specimen trees; they are especially suited to very wet sites, where they produce aerial roots (known as pneumatophores or "knees") at water level.

Hardiness en: Fully hardy.
