The male buds are deeply cleft, to 3/4-5/6, much deeper than in the other members of the group of species with H. hellwigii, to which H. leptantha belongs. The fruits with coarse lenticels and tubercles are reminiscent of those in H. laevigata, and possibly there is a close relationship with this species.
