title: On the identity and typification ofSolanum brasilianumDunal (Solanaceae).
abstract: Solanum brasilianumDunal was described by Dunal in 1813 with reference only to an illustration in an 18thcentury work by Leonard Plukenet. The plate is difficult to interpret and no explicitly related specimens were available so the nameSolanum brasilianumhas long been regarded as "unresolved" and has never been used. Material matching the Plukenet plate was discovered in the herbarium of the University of Oxford (OXF) by Stephen Harris during his study of the English privateer William Dampier's Brazilian collection. The specimen is referable to a common BrazilianSolanumthat is a member of the Torva clade,Solanum paniculatumL., makingSolanum brasilianumDunal a heterotypic synonym. We lectotypifySolanum brasilianumhere, and designate an epitype using the Dampier material from OXF.
