Dryopteris
:''The moth genus ''Dryopteris'' is now considered a junior synonym of ''Oreta. ''Dryopteris'' , commonly called the wood ferns, male ferns (referring in particular to '' Dryopteris filix-mas''), or buckler ferns, is a fern genus in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). There are about 300-400 species in the genus. The species are distributed in Asia, the Americas, Europe, Africa, and the Pacific islands, with the highest diversity in eastern Asia. It is placed in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Many of the species have stout, slowly creeping rootstocks that form a crown, with a vase-like ring of fronds. The sori are round, with a peltate indusium. The stipes have prominent scales. Hybridization and polyploidy are well-known phenomena in this group, with many species form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North American Dryopteris Hybrid Complex
Hybridization and polyploidy are common phenomena in ferns, and the genus ''Dryopteris'' is known to be one of the most freely-hybridizing fern genera. North American botanists recognized early that there were close relationships between many of the species of ''Dryopteris'' on the continent, and that these relationships reflected hybrid ancestry. The complex includes six sexual diploid parents (one of which, "''D. semicristata"'', is hypothesized to be extinct), six sexual allopolyploids, and numerous sterile hybrids at various ploidal levels. Diploid species *'' Dryopteris intermedia'' *'' Dryopteris expansa'' *'' Dryopteris goldieana'' *'' Dryopteris ludoviciana'' *'' Dryopteris marginalis'' *''Dryopteris "semicristata"'' Allopolyploid species *''Dryopteris carthusiana'' (''D. intermedia'' × ''"D. semicristata"''; allotetraploid) *'' Dryopteris campyloptera'' (''D. intermedia'' × ''D. expansa''; allotetraploid) *'' Dryopteris celsa'' (''D. goldieana'' × ''D. ludoviciana''; ...
