Systematics Section Stern, Stephen [1], Bohs, Lynn [2]. A Thorny Tangle in the genus Solanum : Phylogenetic study of Solanum subgenus Leptostemonum. The genus Solanum (Solanaceae) is one of the largest and most economically important plant genera. One of the largest groups within the genus is the Leptostemonum clade with ca. 350-450 species. This clade is also known as the “spiny solanums” due to the presence of epidermal prickles, and it basically conforms to Solanum subgenus Leptostemonum of traditional classifications. Here we present a phylogeny of the spiny solanums with a goal of examining the monophyly of sections recognized within this large clade. Of particular interest is the Micracantha clade, a group of ~12 species that has challenged taxonomists. We clarify the species composition of this clade and further investigate specific relationships within the group using Conserved Orthologous Set (COSII) markers. We examine the utility of these newly developed markers for inferring relationships within the Micracantha clade. These efforts help to define monophyletic groups within the large Leptostemonum clade and will aid in taxonomic revisions of groups within Solanum subgenus Leptostemonum. Broader Impacts:
