A new species of Lindsaea from the Philippines, Lindsaea hamiguitanensis is described. The phylogenetic relationships of L. hamiguitanensis were analysed by sequencing trnL-trnF and trnH-psbA intergenic spacer regions and performing a cladistic analysis of the Lindsaea section Schizoloma. Lindsaea hamiguitanensis groups together with L. bouillodii and L. cf. cambodgensis, from which it differs morphologically by the length of its petioles and the entire pinnules, as well as genetically by three apomorphic substitutions in the trnL-trnF intergenic spacer, and by two apomorphic substitutions in trnH-psbA spacer region.
