Abstract: Gaoligong Mountains is an area that spans the border of Yunnan Province in China and Myanmar. The area is of great botanical interest due to its high botanical diversity, largely undisturbed vegetation, and limited of botanical exploration. The main genera of Araceae in the area are Arisaema, Remusatia, Rhaphi-doprwra, and Typhomum. By far the most common genus is Arisaema with a large diversity of species throughout the area. In the last 10 years a series of major expeditions have explored the area, discovering several new species as well as finding species that were not previously known from the area. From the Gaoligong Mountains area 58 species from 11 genera are listed and discussed, including distribution details. Of these, 10 endemic aroid species, including 3 unpublished species are described. Their distribution are listed and discussed. The geography of Araceae suggests that the Gaoligong Mountains flora is a part of the East Asian flora and that the flora of Eastern Himalayas originated from that of northeastern Myanmar and Gaoligong Mountains.
