Distribution
''Aidia racemosa'' is native to the following regions: Borneo, Caroline Islands, Christmas Island, Gilbert Islands, Hainan, Jawa, Lesser Sunda Islands, Malaya, Maluku, Mariana Islands, Marshall Islands, Nauru, New Guinea, Nicobar Islands, Philippines, Samoa, Solomon Islands, Sulawesi, Taiwan, Thailand, Tonga, Vanuatu, Vietnam, Wallis-Futuna Islands, and the Australian regions of Northern Territory, Queensland, and Western Australia. In the Pacific Islands, ''Aidia'' has commonly been reported as being '' Aidia cochinchinensis.'' However, Tirvengadum noted that the specimens from the Pacific islands were distinct from ''Aidia cochinchinensis'' in Vietnam and in 1988 proposed ''Aidia racemosa'' as a unique species in the Pacific. Fobserg noted a large diversity of phenotypes in the Pacific islands, and in 1993 retained the name ''Aidia cochinchinensis'' as an umbrella term for the Pacific and south Asian types. However, Plants of the World Online (POWO) considers ''Aidia cochinchinensis'' (native to south-central China and Vietnam) and ''Aidia racemosa'' to be unique species.Names
