Limonium tobarrense (Plumbaginaceae), a new species from the southeastern Iberian Peninsula

Abstract

A new species, Limonium tobarrense (Plumbaginaceae), is described from the inland saltmarsh of Cordovilla (Tobarra) in Albacete province, southeastern Iberian Peninsula. This new species is morphologically close to the taxa belonging to the Limonium girardianum group, but there are remarkable differences suggesting separation at species rank. Comparisons are provided with L. dufourii, L. girardianum and L. grosii using multivariate analysis. The principal component analysis (PCA) shows four separated groups, each corresponding to the four species considered. Ecological, phytosociological, bioclimatic, biogeographic and reproductive features of the new species are also discussed, as well as its conservation status. A diagnostic key is provided to facilitate identification of L. tobarrense and its closer allies.
