Abstract
Four new species of <i> Elaphoglossum </i> sect. <i> Elaphoglossum </i> are described: <i> E. Amparoanum </i> A. Rojas, <i> E. Chocoense </i> A. Rojas, <i> E. Fayorum </i> A. Rojas and <i> E. Luciae </i> A. Rojas. The first species is related to <i> E. Variolatum </i> Mickel, but differs from it by having rhizome scales bicolorous and long ciliate margin. The second species is different to <i> E. moranii </i> Mickel by having narrower rhizome, shorter stipe, elliptic blade, attenuate blade base, shorter fertile fronds with blackish costa and present at lower altitudinal distribution . After that, the third species differs from <i> E. lingua </i> (C. Presl) Brack. by pale rhizome scales with long ciliate margin, shorter fronds and blade scales denser and lighter. Finally, the four th species is related to <i> E. atrosquamatum </i> Mickel, but with relative longer fronds and broader blade. The geographical distributions of <i> E. guatemalense </i> ( Klotzsch ) T. Moore , <i> E. longicrure </i> Christ, <i> E. minutum </i> (Pohl ex Fée) T. Moore and <i> E. nicaragüense </i> A. Rojas are expanded.
