This subspecies is unique in its low number of leaflets and its long, attenuate berries which are usually longitudinally creased when dry. It is uncommon and is often found along streamsides in montane, often evergreen forests in the central highlands of Nicaragua from 400 to 1400 m elevation. As yet, no material of this subspecies has been seen in flower or from elsewhere in Central America.
