In this paper three new species of Elaphoglossum Schott ex J. Sm., are
described and illustrated, located on the pacific slope of Cordillera de Talamanca
and Cerro Caraigres (Cerro Dragón), Costa Rica. The new species are: E.
dragonense A. Rojas, E. flavosquamum A. Rojas and E. pacificum A. Rojas, all
belong to the section Elaphoglossum subsection Pachyglossa Christ. The first
species resembles E. gloeorrhizum Mickel but is separated by showing a scaly
rhizome, phyllopodia with two sections, the basal one resinous as the rhizome
and the second non-resinous, bigger stipe scales, and the abaxial blade is scaly.
The second entity resembles E. delgadilloanum A. Rojas, but differs by having
blonde to orange-yellowish rhizome scales with long lateral processes and the
blade scales are mainly smaller, less dense and bicolorous with black central
body and brown rays. The latter species is similar to E. cismense Rosenst., but
is identified by its more slender rhizome, fronds at less distance between them,
shorter phyllopodia, narrowly elliptic blade, bigger abaxial blade scales and a
linear-elliptical and narrower fertile blade
