@ARTICLE{TreeBASE2Ref16712, author = {Philip Mark Moline and Hans Peter Linder}, title = {Molecular phylogeny and generic delimitation in the Elegia group (Restionaceae, South Africa) based on a complete taxon sampling and four DNA chloroplast markers}, year = {2005}, keywords = {}, doi = {}, url = {}, pmid = {}, journal = {Systematic Botany}, volume = {}, number = {}, pages = {}, abstract = {The <i>Elegia</i> group comprises 60 species of African Restionaceae, a large and ecologically dominant element of the Cape flora of South Africa. The recognition of the group was based upon the shared possession of unbranched fertile culms, the presence of a distinct abscission line at the base of the leaf sheaths, and anthers that are included at anthesis. The taxonomy of the group has been problematic, and every monographer of the group used different generic delimitations. Based upon a cladistic analysis of sequence data from multiple chloroplast markers (<i>trnL-F</i> region, <i>atpB-rbcL</i> spacer, <i>trnK</i> intron, <i>matK</i>, and <i>rbcL</i>) for all 60 species, we seek optimal generic groupings that are monophyletic, conservative nomenclaturally, and readily diagnosable using morphological characters. We find no support for the monophyly of the <i>Elegia</i> group, as the genus <i>Askidiosperma</i>, itself forming a clade of 12 species, falls outside the group. Within the remaining elements we find no acceptable generic groupings, consequently we propose an expanded circumscription of <i>Elegia</i> that includes the genera <i>Chondropetalum</i> and <i>Dovea</i>, as these latter two genera are embedded within the former. New combinations are <i>E. acockii, E. aggregata, E. decipiens, E. ebracteata, E. hookeriana, E. marlothii, E. microcarpa, E. recta, E. tectorum, E. macrocarpa</i>.} }
