Assessing phylogenetic relationships in extant heterosporous ferns (Salviniales), with a focus on Pilularia and Salvinia (Botanical Journal of the Linnean Society, 2008-08-01)Heterosporous ferns (Salviniales) are a group of approximately 70 species that produce two types of spores (megaspores and microspores). Earlier broad-scale phylogenetic studies on the order typically focused on one or, ...
Comparative morphology of reproductive structures in heterosporous water ferns and a reevaluation of the sporocarp (International Journal of Plant Sciences, 2006-07-01)Heterosporous water ferns (Marsileaceae and Salviniaceae) are the only extant group of plants to have evolved heterospory since the Paleozoic. These ferns possess unusual reproductive structures traditionally termed "sporocarps." ...
