On the basis of Pruskis key one collection, Wood 16095, from Bolivia (Santa Cruz Cordillera), keys out to P. cummingii, although the specimen has several differences from the type material of this species at K, not least the appearance of the leaves which are pinantely veined, possess a rounded to obtuse lamina base and margins with few short-mucronate teeth.
