ABSTRACT
A new species of Solanum is described from Peru. Solanum junctum S. Stern & M. Nee, sp nov. is a member of the Torva clade of the spiny solanums (Leptostemonum clade). The narrow corolla lobes and recurved prickles of S. junctum are similar to species in the Micracantha clade, but S. junctum differs in its branched inflorescences and upright green fruits. These characteristics are shared with other members the Torva clade; within this section S. junctum is morphologically most similar to S. subinerme and S. poinsettiifolium. Solanum subinerme has larger flowers, longer cauline prickles, and often has long straight prickles on the adaxial leaf surface that are lacking in S. junctum. Solanum poinsettiifolium has fewer spines, dense white tomentum on the abaxial leaf surfaces, stout unbranched inflorescences, and more extensive interpetalar corolla tissue than S. junctum.
