Note — This species has similarities with M. mutetetwa in the shape of leaf blade and indumentum of leaves, but the leaves of M. dasyanthus are in general smaller. Another distinction is its area of occurrence. Monotes dasyanthus occurs in central and southern Angola, Zambia and Western Katanga, whereas M. mutetetwa occurs in the north of Angola and the south-east of the Democratic Republic of the Congo.
