Widespread in Tropical Asia. India, Sri Lanka, China (south only: Guangdong, Hainan, Hong Kong), Taiwan, Japan: Ryukyu Isl., Bonin Isl.; Indochina; in Malesia: Peninsular Malaysia, Java, Lesser Sunda Islands, Borneo, Philippines, Celebes, Moluccas?, New Guinea; New Caledonia, Australia: Queensland; New Zealand: Kermadec Isl.; Pacific: Fiji, Pitcairn; Rapa; Society Isl.; Cook Isl.; Tonga. Introduced in Tropical America and the Hawaiian Islands.
Judging by the distribution of early collections, almost certainly native in Malesia, but dubiously elsewhere. It is certainly introduced in America, where it is spreading as a weed and classified as an invasive species in Florida ().


This species has often been confused with N. hirsutula. Characters to distinguish these two species are discussed under N. hirsutula. Similar scales and costal indument is found in N. acuminata, which is, however, easily distinguished by the rhachis indument including at least some scales with a dark acicular apex.
