Abstract

Phylogenetic relationships among the seven genera of the Hypopterygiaceae, represented by 14 of the 21 species recognized in the family, are reconstructed based variation in nucleotide sequences of six nuclear, mitochondrial, and plastid loci. Monophyly of the Hypopterygiaceae is strongly supported, whereas Cyathophorum and Dendrohypopterygium are unambiguously polyphyletic. Cyathophorum bulbosum and C. adiantum comprise a lineage sister to the remainder of the family. A lineage comprising three monotypic genera (Canalohypopterygium, Catharomnion, and Dendrocyathophorum) and Dendrohypopterygium arbusculum is sister to Lopidium plus a heterogenous clade that includes Dendrohypopterygium filiculaeforme, Hypopterygium, Cyathophorum hookerianum, and C. parvifolium. The later two species are transferred to Hypopterygium as H. hookerianum and H. parvifolium. The Hypopterygiaceae are distinguished from their sister family, the Hookeriaceae, by their anisophylly, and by a border of 2 or more differentiated cells on lateral leaves, although this character also occurs in the Hookeriaceae and has been lost at least twice in the Hypopterygiaceae. Intermediate cells in the axillary hairs arose early in the evolution of the family but are lacking in the two species of Cyathophorum that form a sister group to the remainder of the Hypopterygiaceae.
