An overlooked or elusive species? Adiantum raddianum (Pteridaceae), a new record for Honduran Flora

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

Adiantum raddianum is reported as a new record for the Honduran Flora. This new occurrence of A. raddianum closes a gap of distribution between Guatemala and Nicaragua. We consider this species vegetably similar to these species of Adiantum in Honduras: A. raddianum, A. amplum, A. andicola, A. capillus-veneris, A. concinnum, A. tenerum, and A. thalictroides. A key to related species is provided.

Key words:
distribution; ferns; Mesoamerica; taxonomy
