Abstract

The present revision ofSolanum sect.Brevantherum Seithe recognizes 12 species in North and Central America, 5 of which (S. brevipedicellatum, S. axillifolium, S. atitlanum, S. pulverulentifolium, and S. chiapasense) are described as new. The traditional methods of comparative morphology are employed in delimiting the species in the herbarium, but pertinent data from field work are also included. Some of the most diagnostic features are those associated with the buds, calyces, and hairs. A key to the species is based on both vegetative and floral characters. Distribution maps show the widespread nature of some species and the endemism of others. All of the species are weedy and are associated with secondary growth vegetation.
