In 1990, Kramer and Green expanded the genus Odontosoria to include essentially all lindseaoid species with continuous axial sulcation and laterally adnate indusia. As so defined, Odontosoria appears to be unnaturally broad and contains widely disparate elements. The goals of this study were to provide a set of data sufficiently extensive to confirm or reject this generic delimitation, as well as to define the generic and species boundaries among the taxa. Toward this end, a series of collecting trips in the Bahamas (1995), the Philippines (1996, 1997), Puerto Rico (1997), Hawaii (1997), and Jamaica (1997) was undertaken. These collections were studied in conjunction with 4,798 sheets of herbarium specimens representing 3,134 collection numbers and 35 photographs from 22 herbaria. One to 30 specimens per species were sampled for a total of 109 morphological and anatomical characters. Putative phylogenetic relationships of the odontosorioids as well as of the dennstaedtioid and the lindsaeoid genera are discussed in light of both traditional (morphological and anatomical) and/or molecular data. Odontosoria sensu Kramer and Green is considered to be a paraphyletic assemblage of taxa held together by pleisiomorphies. A generic circumscription for the Odontosoria complex is proposed which consists of five component genera, Bierhorstia (four species and three varieties), Lourdesia (four species), Odontodesia (one species), Odontosoria sensu stricto (10 species), and Sphenomeris (five species). The first three genera are new and are fully described here. One new species, Lourdesia celebesiana, is described, one variety is elevated to species rank (Bierhorstia divaricata), one variety of Bierhorstia chinensis is renamed as var. capitata, and 14 new combinations are proposed. Taxonomic keys to and descriptions of the genera and their species are provided. Taxonomic descriptions are complemented by representative scientific illustrations for 10 species. The presence and descriptions of new taxa in this dissertation are not intended to represent valid or effective publication.
