They grow naturally in the rainforests of New Guinea, the Moluccas, Sulawesi, Borneo, the Philippines and Cape York Peninsula, far northern Queensland, Australia.[3][4][5][6][7][8]

European science formally described the genus and the two known species in 1847, authored by botanist Carl Ludwig Blume.[1][2][3][4]

J. van Dijk's genus review scientific paper and Flora Malesiana account described a different taxon of a single poor quality specimen of some broken parts of leaves collected in the Moluccas. As it is of so poor quality it is of uncertain status, either as a variant of D. acuminata having leaves wider than its usual 5 cm (2.0 in) or a different species; a decision requires more quality specimens.[3][4]

Species
  • Dictyoneura acuminata Blume – Borneo, Philippines, Sulawesi, Moluccas, New Guinea[7][9]
    • subsp. acuminata – Borneo, Philippines, Sulawesi, Moluccas, New Guinea[10]
    • subsp. microcarpa Dijk – W. New Guinea[11]
  • Dictyoneura obtusa Blume – New Guinea, New Ireland, New Britain, Cape York Peninsula, Australia,[6][12] its records of significant variation across New Guinea may turn out to lead to descriptions of new taxa[13]
