A new species of Musschia Dumort. (Campanulaceae), endemic from Madeira Archipelago (Portugal), is described as Musschia isambertoi M. Seq., R. Jardim, M. Silva & L. Carvalho. Both vegetative and reproductive structures have been studied and are remarkably distinct from the recognized species [M. aurea (L. f.) Dumort. and M. wollastonii Lowe]. A full description and a diagnosis are included as well as line art, color drawings and pictures. Diagnostic characters are discussed and compared with those of the closely related species. The new species has a very restricted distribution occurring in two isolated populations in the Deserta Grande Island (Madeira Archipelago, Portugal). Nomenclatural aspects on the genus Musschia Dumort. are discussed and a diagnostic key for the species is also included
