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.The first well-sampled molecular phylogenetic study of the vittarioids was based on the chloroplast gene rbcL.
