From papers of the different authors published from 1995 to 2009 and the recent investigations in Cambodia, Laos and Vietnam, 67 new discoveries in the family Araceae in Indochina have been accounted. Among them, 38 species are new for science and 29 species are new records for Flora of Indochina. The new species were found mainly from Vietnam (28 species), from Laos (8 species) and from Cambodia (2 species). Among the 29 new species records for Flora of Indochina, 15 species are found in China, 10 species are found in Thailand, 3 species are found in Myanmar and only one species is found in Indonesia. This means that the species composition of the family Araceae in Indochina is mostly affected by the migration of species coming from China and Thailand. The factor of species migration from Indonesian region has little effects on the family in Indochina.
