Discusión taxonómica
This species is remarkable for its large 4- or 5-valved, strongly depressed-globose, deeply sulcate fruits. No other Mortoniodendron has been reported with 5-valved fruits. The leaves, conspicuously inaequilateral at base and trinerved, have the basal nerves strongly ascending and often extending to the middle of the blade. The pubescence of the leaves, fine and silky beneath, smaller and coarser above, is primarily along the costa and veins. The costa and nerves have small barbate domatia in axils on the lower surface.A
