Poranthera leiosperma is most closely related to P. microphylla. It differs from P. microphylla by having seeds with a smooth rather than tuberculate surface, longer leaves (11-15 mm long as compared with 6-11 mm long) and longer stipules (1.3-1.6 mm long as compared with 0.8-1.3 mm long). Poranthera leiosperma also differs from P. microphylla in its slightly more robust growth habit.
