TL;DR: Within the Carolinense clade, the North and South American species were both recovered as well-supported clades, implying a single dispersal event from South to North America.
Abstract: The large and economically important genus Solanum contains ca. 1,400 species distributed worldwide. One of the 12–14 major clades identified in the genus is the Leptostemonum clade, or tire “spiny solanums.” Previous molecular phylogenetic studies have identified 14 major clades in the spiny solanums. Among these is the Carolinense clade, which contains Solanum carolinense, the type species of S. subsect. Lathyrocarpum. However, previous results have suggested that the species composition of the Carolinense clade is only partially congruent with taxonomic circumscriptions of S. subsect. Lathyrocarpum. The main goal of this study was to increase taxon sampling over previous molecular phylogenies in order to better understand the composition of the Carolinense clade. We newly sequenced 31 accessions of 17 taxa putatively belonging to the clade for two nuclear (ITS, waxy) and one plastid gene region (trnT-trnF) and combined these with previously generated molecular data. Phylogenetic analyses of se...

TL;DR: A new species of Solanum from Texas is described, similar to S. citrullifolium and S. davisense but differs from both in having white corollas, and differs from the latter in having inflorescences with a significantly longer axis and larger flowers.
Abstract: A new species of Solanum from Texas is described here. Solanum cordicitum S. Stern is a member of Solanum section Androceras. It is similar to S. citrullifolium and S. davisense but differs from both in having white corollas, and differs from the latter in having inflorescences with a significantly longer axis and larger flowers. In addition to the new species, three new combinations are proposed for species in Solanum section Androceras, Solanum setigeroides (Whalen) S. Stern, Solanum novomexicanum (Bartlett) S. Stern, and Solanum knoblochii
