| Abstract Detail
Systematics Floden, Aaron J [1]. Updated analyses of the axillary-flowered Polygonateae (Asparagaceae): Disporopsis, Heteropolygonatum, and Polygonatum. Disporopsis, Heteropolygonatum, and Polygonatum have recently all had novel species described or transferred from other genera. Systematic investigations into the generic boundaries of Heteropolygonatum and Polygonatum have corroborated the monophyly of the former and resulted in an increase of species number in both genera. Heteropolygonatum now has 10 species and Polygonatum has more than 73, with a high likelihood for additional novelties. Expanded molecular phylogenetic analyses of all three genera using chloroplast, mitochondrial, and nuclear loci are presented. These data combined with field work and morphological data have resulted in the description of two Disporopsis, five Polygonatum, the transfer of one Polygonatum to Disporopsis, four Polygonatum to Heteropolygonatum, resulted in the reinstatement of P. govanianum, and revealed numerous as yet unresolved taxonomic problems in several species groups. The results of these studies highlight the need for further taxonomic investigation into the alpha level diversity of understudied and species-rich genera in the biodiverse regions of southeastern Asia.
