Discusión taxonómica
Diplazium gomezianum differs from congeners in Mexico by having fully 3-pinnate to 3-pinnate-pinnatifid blades proximally and nearly equilateral pinnules. Specimens of this species were previously identified as D. herbaceum Fée (Smith, 1981: 96), a name that should be restricted to a Brazilian species, according to Adams (1992).A
