FARFAN-ROLDAN, Ixhel; GOMEZ-ALANIS, Cristina  y  ARREGUIN-SANCHEZ, María de la Luz. UN NUEVO HÍBRIDO PARA MÉXICO DE PLEOPELTIS POLYLEPIS (ROEMER EX KUNZE) T. MOORE VAR. POLYLEPIS X POLYPODIUM GUTTATUM MAXON. Polibotánica [online]. 2006, n.22, pp.9-19. ISSN 1405-2768.

A new hybrid fern from Mpio. Mineral de Chico, Hidalgo, Mexico, is described and illustrated. Or if the hybrid is already known from somewhere else but is new to Mexico,This interesting plant combined characteristics of Pleopeltis polylepis (Roemer ex Kunze) T. Moore var. Polylepis (scaly stipes, presence of soral scales or paraphyses, netted veins) and Polypodium guttatum Maxon (rhizome scales not comose, leaves with hydathode pits). It showed intermediacy between the suspected parental species in the gradations of blade division (irregularly deeply lobed to pinnatifid) and abaxial blade scales (P. polylepis var. polylepis color and P. guttatum form).
