The application of the name Hexalobus jussiaeanus Baill. has remained unclear since its original publication in 1868. The type, and sole basis of the species, is a specimen in the Jussieu Herbarium in Paris that lacks any information on its origins. The Jussieu specimen is found to be a collection of Uvaria narum (Dunal) Blume (Annonaceae), a species from southern India and Sri Lanka. Hexalobus jussiaeanus should therefore be considered a junior synonym of Uvaria narum.
