The subsessile infructescences with rather stout, short, 1-2 mm long peduncle suggest that male inflorescences may be (short) paniculate, with a more or less distinct peduncle, pointing to a relationship with M. agusanensis. The latter species differs in the minute indumentum on its lower leaf surface (± glabrescent), and in its smaller fruits.
