Discusión taxonómica
Elaphoglossum ellipticifolium resembles E. productum in its long and orange-brownish rhizome scales, and blackish abaxial blade scales, but differs in having short creeping (vs. compact) rhizome, broader (1.5-2.5 mm wide vs. 0.5-1.5 mm) and marginally entire (vs. ciliate) rhizome scales. It is also similar to E. latifolium, but differs in having larger (10-20 x1.5-2.5 mm vs. 5-9 x 0.5-1.0 mm) rhizome scales, longer [1/3-2/5 of frond length vs. 1/6-1/4 (-1/3)] stipes, broadly elliptic (vs. elliptic) blades, and blackish (vs. orange-reddish to pale brown) abaxial blade scales. This species is named E. ellipticifolium for the elliptic blade.A
