Taxonomy
Horsfieldia majuscula can be confused with H. poly spherula var. sumatrana and var. maxima. Variety sumatrana differs in usually coarser hairs on the leaf buds, more contrasting colour of the two surfaces of dry leaves, smaller globose male perianths, essentially different androecium, and smaller fruits, up to 35 mm long. Variety maxima, known only from Borneo, differs in the same characters, but has fruits of a similar size as those of H. majuscula, with the pericarp up to 15 mm thick.
