Editing Indomalayan realm (section)

== History ==
The flora of Indomalaya blends elements from the ancient supercontinents of [[Laurasia]] and [[Gondwana]]. Gondwanian elements were first introduced by India, which detached from Gondwana approximately 90 [[mya (unit)|MYA]], carrying its Gondwana-derived flora and fauna northward, which included [[cichlid]] fish and the plant families [[Crypteroniaceae]] and possibly [[Dipterocarpaceae]]. India collided with Asia 30-45 MYA, and exchanged species. Later, as [[Australia-New Guinea]] drifted north, the collision of the Australian and Asian plates pushed up the islands of [[Wallacea]], which were separated from one another by narrow straits, allowing a botanic exchange between Indomalaya and [[Australasian realm|Australasia]]. Asian rainforest flora, including the dipterocarps, island-hopped across Wallacea to New Guinea, and several Gondwanian plant families, including [[podocarp]]s and [[araucaria]]s, moved westward from Australia-New Guinea into western Malesia and Southeast Asia.
