Identity of Linaria × versicolor (Antirrhineae, Plantaginaceae) and typification of its basionym

Abstract

The identity of Linaria ×versicolor (Jacq.) Chaz. is discussed, supporting a hybrid origin in cultivation that involved species of the North African clade of Linaria subsect. Versicolores as parents. Due to the lack of original material, a neotype specimen from the SEV herbarium is designated for the basionym Antirrhinum versicolor Jacq. Ornamental plants usually known as “L. maroccana hort.” correspond to this taxon, and not to L. maroccana Hook.f., one of the putative parents, native to the High Atlas (Morocco).
