(2639) Proposal to reject the name Solanum frutescens (Solanaceae).

The members of the Morelloid clade of Solanum (the black nightshades sensu Särkinen & al. in Taxon 64: 945-958. 2015) have long been considered difficult, and are nomenclaturally complex (e.g., Edmonds in Bot. J. Linn. Soc. 89: 165-170. 1984). As part of an ongoing revision of this group worldwide, we have encountered a name based on cultivated plants that appears to apply to a well-known species and that has priority over the name in current use, and whose uptake would cause considerable confusion in an already complex group. Rejection will stabilise nomenclature for species of the Morelloid clade of Solanum, and prevent use of destabilising names in the future. [ABSTRACT FROM AUTHOR]
