This variety differs mainly in its conspicuously large and almost globose fruits with a very thick pericarp. It may be confused with H. majuscula from Peninsular Malaysia, which differs from H. polyspherula in the size of the male flowers (flowers of var. maxima are unknown), a different androecium, leaf colour, and somewhat in the fruits with a thinner pericarp.

Fruiting specimens of H. polyspherula var. maxima may also be confused with H. punctatifolia, which differs in its dotted leaves.
