Discusión taxonómica
This species is mostly likely to be confused with Loxogramme mexicana, which differs in having fewer sori closer to the midrib and more nearly parallel to it. From species of Polytaenium it differs by the numerous paraphyses with a spherical tip and the bilateral spores. It is relatively common in Chiapas, Oaxaca, and Veracruz, in suitable habitats, but rare or uncommon elsewhere in Mexico.
Schaffner 71 (NY), “Valley of Mexico,” 1875, is no doubt the basis for citation of this species from Edo. México by Mickel and Beitel (1988), but the specimen is most likely from San Luis Potosí (Rzedowski, 1959), where Schaffner is known to have collected extensively during this time. Another specimen with the same number at NY, but without year, is labelled as from San Luis Potosí, and a third collection, dating from 1876, “Santa María de Rey,” but without state, is probably also from San Luis Potosí (cuenca del río de Santa María; Rzedowski, 1959: 102).
