Discusión taxonómica

The lunate indusia, pinna bases that are cuneate basiscopically, and essentially parallel-sided pinnae distinguish this species from its most similar congeners (N. pendula and N. undulata) in Mexico. Díaz-Barriga and Palacios-Rios (1992: 48) cited Arsène 6690 (MEXU), from Michoacán, as N. pectinata and also as N. cordifolia, but the specimen has not been found at MEXU (March 1998); most likely, it is not N. pectinata.A
