Strong selective pressures imposed by drought-prone habitats have contributed to extensive morphological convergence among the 400 + species of cheilanthoid ferns (Pteridaceae). As a result, generic circumscriptions based exclusively on macromorpholo

Cheilanthoid ferns (Pteridaceae) are a diverse and ecologically important clade, unusual among ferns for their ability to colonize and diversify within xeric habitats. These extreme habitats are thought to drive the extensive evolutionary convergence

Four members of the alpha-tubulin gene family were examined in Ceratopteris richardii. Genetic linkage mapping based on a population of nearly 500 Doubled Haploid Lines was able to position three or four members of this gene family on linkage groups

Nucleotide sequences of the chloroplast-encoded rbcL gene were determined for Loxoscaphe thecifera and Actiniopteris radiata and used in maximum parsimony cladistic analyses to determine their phylogenetic positions in the context of a broad range of

Nucleotide sequences of the chloroplast-encoded rbcL gene were determined for all five species of the onocleoid ferns (Dryopteridaceae tribe Onocleeae), including both varieties of Onoclea sensibilis, and for outgroup member Blechnum glandulosum. Tog

The cheilanthoid ferns have long resisted efforts to circumscribe well-defined, phylogenetically natural generic and infrageneric groups, presumably because of homoplastic morphologies associated with their xeric habitats. This cladistic analysis of
