Neoalsomitra contains 11 species, one of which, N. clavigera, is widespread, covering the whole range of the genus from NE India and S China into Australia and the Pacific. The genus is heterogeneous in having species with free stamens and species with the filaments connate; however, this cannot be used for subdivision. Neoalsomitra hederifolia and N. schefferiana are podagric succulents, i.e. with thickened stem-bases. Neoalsomitra pilosa W.J. de Wilde & Duyfjes (New Guinea) is newly described; new combinations are N. hederifolia (Decne.) W.J. de Wilde & Duyfjes and N. schefferiana subsp. podagrica (Steenis) W.J. de Wilde & Duyfjes.
