The higher mountains rise abruptly from the plains; on their slopes, clothed below almost exclusively with the more tropical forms, a vegetation of a warm temperate character, chiefly evergreen, soon begins to prevail, comprising Magnoliaceae, Ternstroemiaceae, subtropical Rosaceae, rhododendron, oak, Ilex, Symplocos, Lauraceae, Pinus longifolia, with mountain forms of truly tropical orders, palms, Pandanus, Musa, Vitis, Vernonia, and many others.
The grape-vine, botanically Vitis, is a genus of about thirty species, widespread in the north temperate zone, but richest in species in North America.
