Nomenclatural notes on some species of Solanum L. found in Europe

The nomenclatural changes which have become necessary for several species belonging to Solanum section Solanum since they were revised during the preparation of Flora Europaea are given and discussed. S. villosum is now recognized as the correct name for S. luteum , and this has necessitated a new combination for the eglandular subspecies of this taxon, namely, S. villosum Miller subsp. puniceum (Kirschleger) Edmonds. The two species were described simultaneously by Miller, and the precedence of the epithet villosum over the epithet luteum is fully discussed, together with the reasons for the selection of puniceum as the second subspecific name. The species previously referred to as S. melanocerasum is now known to be synonymous with S. scabrum , while S. chenopodioides becomes the correct name for S. sublobatum. Complete lists of synonyms are given for these three species, together with extensive notes on the more controversial and difficult synonymy. Finally, reasons are given to justify the spelling of S. sarrachoides with two r's.
