Vittarioideae is a subfamily of the Pteridaceae family of ferns,〔 in the order Polypodiales, class Polypodiopsida. This subfamily includes the previous families Adiantaceae (adiantoids or maidenhair ferns) and Vittariaceae (vittarioids or shoestring ferns).〔 The following diagram, shows a likely phylogenic relationship between the Vittarioideae and other subfamilies of the Pteridaceae.〔(Schuettpelz & Pryer (2008) "Fern phylogeny" in ''Biology and Evolution of Ferns and Lycophytes'' ), ed. Tom A. Ranker and Christopher H. Haufler. Cambridge University Press 2008〕〔(Schuettpelz ''et al.'' (2007) ) Eric Schuettpelz, Harald Schneider, Layne Huiet, Michael D. Windham, Kathleen M. Pryer: "A molecular phylogeny of the fern family Pteridaceae: Assessing overall relationships and the affinities of previously unsampled genera." ''Molecular Phylogenetics and Evolution'' 44 (2007) 1172–1185〕 }} }} The first well-sampled molecular phylogenetic study of the vittarioids was based on the chloroplast gene rbcL.〔Bradley Ruhfel, Stuart Lindsay, and Charles C. Davis. 2008. "Phylogenetic Placement of ''Rheopteris'' and the Polyphyly of ''Monogramma'' (Pteridaceae s.l.): Evidence from rbcL Sequence Data". ''Systematic Botany'' 33(1):37-43, 〕 In this study, it was found that the type species of ''Monogramma'' is embedded in ''Haplopteris''. Because ''Monogramma'' is the older name, unless ''Haplopteris'' is split, all of the species of ''Haplopteris'' will eventually be transferred to ''Monogramma''. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vittarioideae」の詳細全文を読む スポンサード リンク
