The two-fold origin of the ligneous flora of the South Indian hill stations is reflected in their ecological divergence: (1) the forest species of tropical stock are restricted to the valleys and depressions with higher moisture content and (2) other sites carry savanna, the woody elements of which are of extra-tropical origin, relics of previous cooler climates of the Pleistocene. Whereas the winter cold proves deleterious to the regeneration of the forest species of tropical stock in the open areas, the ligneous species of the savanna of subtropical or temperate stock survive the frost. On the basis of climatic characteristics it is shown that the climate of these hill stations is not temperate as almost invariably described, but of tropical montane type.
