ABSTRACT: In this research three new
species of ferns of the Polypodiales Order are described: Ctenitis leonii A. Rojas, Elaphoglossum karinae A. 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.
