Abstract

We describe a new species of spinySolanum(Solanumsubg.Leptostemonum), endemic to the Brazilian Atlantic Forest and associated with granitic outcrops (inselbergs or sugar loaf mountains).SolanumkollastrumGouvêa & Giacomin,sp. nov.is morphologically similar to the poorly knownS.sublentumHiern, but is a heavily armed, much more robust plant with stellate-glandular indumentum. Together withS.sublentum, it is morphologically related to some species ofSolanumsuch asS.hexandrumVell.,S.robustumH.Wendl., andS.stagnaleMoric. that share strongly accrescent calyces, large leaves with the bases decurrent on to the petiole, pendent simple inflorescences and large, robust flowers. The new species is restricted to a few known populations in southern Bahia and north-eastern Minas Gerais states and conservation efforts are needed.
