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.

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.展开更多

Rojas and Pecluma celaquensis A. Rojas. Ctenitis leonii is characterized by its apical stipe scales marginally erose to ciliate, blade surfaces with two types of hairs present in both surfaces, ones 0.7 - 1.5 mm long and not glandular, the others 0.3 - 0.5 mm long and glandular and indusia are absent. Elaphoglossum karinae differs from Elaphoglossum dissitifrons Mickel by shorter rhizome, longer and relatively narrower rhizome scales, they lanceolate to linear-lanceolate and blackish costal scales. Pecluma celaquensis is similar to Polypodium martensii Mett., but differs by its thinner rhizome, smaller rhizome scales and these with a crown of brown cilia at the attaching point, relatively shorter stipe with longer hairs and these commonly no glandular, scaly rachis and it with longer and denser hairs, inframedial sori and glabrous sporangia.展开更多
