ABSTRACT: Four new species of Elaphoglossum sect. Elaphoglossum are described: E. Amparoanum A. Rojas, E. Chocoense A. Rojas, E. Fayorum A. Rojas and E. Luciae A. Rojas. The first species is related to E. Variolatum Mickel, but differs from it by having rhizome
scales bicolorous and long ciliate margin. The second
species is different to E. moranii 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 E.
lingua (C. Presl) Brack. by pale rhizome scales
with long ciliate margin, shorter fronds and blade scales denser and lighter. Finally,
the fourth species is related to E.
atrosquamatum Mickel, but with relative longer fronds and broader blade. The geographical distributions of E.
guatemalense (Klotzsch) T. Moore, E. longicrure Christ, E. minutum (Pohl ex Fée) T. Moore and E.
nicaragüense A. Rojas are expanded.
