Discusión taxonómica

(In relation to the synonym Elaphoglossum lepidopodum) This species is probably closest to E. guatemalense, agreeing with that in its slender rhizomes, lustrous rhizome scales (at least with age), irregularly toothed stipe scales, distinct phyllopodia, reduced black stellate blade scales, and distribution on the Pacific slope, but E. lepidopodum differs in its very slender fronds, thin blade texture, and scaly stipes.A
