Systematics Section/ASPT Monfils, Anna K. [1], Shiels, Derek R. [2], Starr, Julian [3], Dame, Heather E. [4], Pozo, David [2], Shorkey, Adriane L. [2], Schick, Elizabeth R. [2]. Phylogeny of the paraphyletic Fuireneae (Cyperaceae). Tribe Fuireneae consists of six genera (Actinoscirpus, Pseudoschoenus, Fuirena, Bolboschoenus, Schoenoplectus, and Schoenoplectiella) and approximately 155 species that are distributed widely across all continents except Antarctica. Recent molecular phylogenies suggest Fuireneae is a paraphyletic tribe, but relationships among its genera and relative to those positioned in the closely related tribe Cypereae remain unstable. In order to clarify relationships, all six Fuireneae genera including representatives from the closely related tribes Abildgaardieae, Cypereae, and Eleocharideae were sequenced for five coding and non-coding regions of the nuclear (internal transcribed spacer, ITS) and chloroplast (trnL intron and trnL-trnF spacer; ndhF, rbcL and matK genes) genomes. Parsimony, likelihood and Bayesian analyses of a 37-taxon dataset strongly support Fuireneae as a grade of three well supported lineages: Fuirena, Bolboschoenus and a clade containing tribe Cypereae and all remaining Fuireneae genera (Schoenoplectus, Schoenoplectiella, Actinoscirpus and Pseudoschoenus). These results strongly suggest that tribe Fuireneae is unnatural and needs to be revised.
