In his 1972 monograph, Paul Maas described a separate variety scabremarginatus based only on minor differences in the distribution of the hairs on the leaves. Variety lima was described as having leaves with the upper side scabrid to the touch, but variety scabremarginatus is described as having leaves with the upper side "only somewhat scabrid towards the margins". I was never able to discern these minor differences in hairs in the field. For the proposed revision to new world Costaceae, Dr. Maas decided to eliminate the separate varieties. "Too many intermediates between var. lima and var. scabrimarginatus convinced us to unite both varieties."
