Outline of Final Research Achievements |
A number of species complexes possibly originated from "reticulate evolution" which involves hybridizations and polyploidizations are present in the fern and lycophyte flora of Japan. We clarified biological entities of 20 complexes selected from Hymenophyllacae, Thelypteridaceae, Lindsaeaceae, Dennstaedtiaceae, Pteridaceae, Cystopteridaceae, Aspleniaceae and Dryopteridaceae by ploidy and mollecular phylogenetic analyses. Taxonomic and/or nomenclatural revisions were made for the complexes whose names did not correspond to their biological entities.
