Taxonomic and nomenclatural notes on Philippine ferns. I. The identity of Asplenium anisodontum C.Presl (Aspleniaceae)

Abstract

The synonymy of Asplenium unisodontum C.Presl (Aspleniaceae) in the Philippines is clarified. Asplenium anisodontum C.Presl. A. longissimum Blume and A. caudatum G.Forst. are different species. A. anisodontum C.Presl and A. longissimum Blume are both found in the Philippines. The presence of Asplenium cuudatum G.Forst. in the Philippines is doubtful. Asplenium acutiusculum Blume is the same as A. longissimum Blume and the latter name should be accepted.
