It is characterized by its needle-leaved Coniferae, its catkin-bearing (Amentaceae) and other trees, deciduous in winter, and its profusion of herbaceous species.
Amongst Coniferae Podocarpus is common to this and preceding sub-regions; Libocedrus extends from California to New Zealand and New Caledonia; Fitzroya is found in Chile and Tasmania; and Araucaria in its most familiar species occurs in Chile.
The "deciduous cypress," "swamp cypress" or "bald cypress," Taxodium distichum, is another member of the order Coniferae (tribe Taxodineae), a native of the southern United.
Only one pine is found below 8000 ft., above which several other Coniferae occur.
The mountains are clothed, where the fall of rain is abundant, with forests of Quercus, Fagus, Ulmus, Acer, Carpinus and Corylus, and various Coniferae.
