New species and new records in Elaphoglossum sect. Polytrichia subsect. Hybrida (Dryopteridaceae) from the Neotropics

Abstract

Three new species of Elaphoglossum sect. Polytrichia subsect. Hybrida from the Neotropics are described here: E. lucens, E. martinezianum, and E. reductum. The first species is characterized by blackish, lustrous and rigid rhizome scales and short fertile fronds. The second species is characterized by stipe and blade margins with long scales and blades elliptic and abaxially scaly. The third species is easy to recognize by small and curved scales and obovate blades. New geographic records are reported for three species, thus expanding their ranges. © 2010, Americian Fern Society.
