  • Discussion

    Type. Venezuela. Me´rida: trail leading from La Negrita to the Boquero ´n of the Quebrada de las Can˜as, Luteyn 6139 (NY!).

    Elaphoglossum pilosius is close to E. lindenii, but the former has rounded to truncate blade bases, and the stipes and blades are conspicuously scaly.

  • Distribution

    Epipetric on pine-oak slopes; 2750–3200 m. Mexico; CR, Pan; Col, Ven, Ec, Peru.
