Discusión taxonómica
Diplazium vera-pax has the appearance of a hybrid between a simple-bladed species, quite likely D. plantaginifolium, and a 1-pinnate species, perhaps D. werckleanum. Mickel and Beitel (1988) and Adams (in Davidse et al., 1995) used the name D. riedelianum (Bong. ex Kuhn) Kuhn ex C. Chr., based on a Brazilian type, for this taxon, but D. riedelianum has the proximal pinna pair slightly lobed, with sori on several veins of a vein group, rather than on only the anterior vein of a vein group. It seems a distinct possibility that D. riedelianum and D. vera-pax are not conspecific and, if both hybrids, are of different parentage, since D. werckleanum is unknown from South America. Comparative isozymic or DNA sequence studies might prove illuminating.
