[4] It is native to China, the Indian Subcontinent, Southeast Asia, Papuasia, and Queensland.

[1][5][6][7] When the genus was erected by Carl Ludwig Blume in 1825, he used the spelling Aporosa but in a publication the next year he used the spelling Aporusa and some publications and Herbert Airy Shaw in 1966 argued that the second spelling was preferred due to common usage.

[9] Four species (A. hermaphrodita, A. heterodoxa, A. brevicaudata, and A. egreria) have consistently bisexual flowers, although they may be functionally dioecious.

[3] Based on fossil evidence, the genus has been hypothesized as having its origins in the Indian Subcontinent from where it may have dispersed into Southeast Asia.
