Subsp. hybrida belongs with some doubt to M. warburgii, whereas it also may be related to M. gracilipes. Male flowers of subsp. hybrida are unknown, and the seed of the type specimen is not yet fully developed. The subspecies differs mainly in the distinct, contrasting nervation on the lower leaf surface.
