Editing Indomalayan realm (section)

== Flora ==
The subfamily [[Dipterocarpoideae]] comprises characteristic tree species in Indomalaya's moist and seasonally dry forests, with the greatest species diversity in the moist forests of [[Borneo]].<ref>Appanah, Simmathiri and Jennifer M. Turnbull, eds. (1998). ''A Review of Dipterocarps: Taxonomy, ecology and silviculture.'' Center for International Forestry Research, 1998.</ref> Teak (''[[Tectona]]'') is characteristic of the seasonally dry forests of the Indomalaya, from India through Indochina, Malaysia, and the Philippines. Tropical pitcher plants (''[[Nepenthes]]'') are also characteristic of Indomalaya, and the greatest diversity of species is in Sumatra, Borneo, and the Philippines.

The tropical forests of Indomalaya and Australasia share many lineages of plants, which have managed over millions of years to disperse across the straits and islands between Sundaland and New Guinea. The two floras evolved in long isolation, and the fossil record suggests that Asian species dispersed to Australasia starting 33 million years ago as Australasia moved northwards, and dispersal increased 12 million years ago as the two continents approached their present positions. The exchange was asymmetric, with more Indomalayan species spreading to Australasia than Australasian species to Indomalaya.<ref>Ebach, Malte C. (2017). ''Handbook of Australasian Biogeography''.
