Hindustanian-Indochinean area covers large part of the Indian Peninsula, countries as Burma, Thailand, Laos, Cambodia, Vietnam and Taiwan. Northern frontier is formed by the southern range of Himalayas. We can find here 35 000 species with great measure of endemism. Attachment to the other floristic regions exists from development view mainly to the Paleotropis and Neotropis. But this sub-region is influenced also by Holarctis and by Indonesian-Papuan sub-region.
