AB Plumbaginaceae is characterized by a history of multiple taxonomic rearrangementsand lacks a broad molecular phylogenetic framework. Limonium is the most speciesrichgenus of the family with ca. 600 species and cosmopolitan distribution. Its centerof diversity is the Mediterranean region, where ca. 70% of all Limonium species areendemic. In this study, we sample 201 Limonium species covering all described infragenericentities and spanning its wide geographic range, along with 64 species ofother Plumbaginaceae genera, representing 23 out of 29 genera of the family.Additionally, 20 species of the sister family Polygonaceae were used as outgroup.Sequences of three chloroplast (trnL‐F, matK, and rbcL) and one nuclear (ITS) loci wereused to infer the molecular phylogeny employing maximum likelihood and Bayesiananalyses. According to our results, within Plumbaginoideae, Plumbago forms a nonmonophyleticassemblage, with Plumbago europaea sister to Plumbagella, while theother Plumbago species form a clade sister to Dyerophytum. Within Limonioideae,Ikonnikovia is nested in Goniolimon, rejecting its former segregation as genus distinct from Goniolimon. Limonium is divided into two major clades: Limonium subg. Pterocladoss.l., including L. sect. Pteroclados and L. anthericoides, and L. subg. Limonium. The latteris divided into three well‐supported subclades: the monospecific L. sect.Limoniodendron sister to a clade comprising a mostly non‐Mediterranean subcladeand a Mediterranean subclade. Our results set the foundation for taxonomic proposalson sections and subsections of Limonium, namely: (a) the newly described L. sect.Tenuiramosum, created to assign L. anthericoides at the sectional rank; (b) the morerestricted circumscriptions of L. sect. Limonium (= L. sect. Limonium subsect. Genuinae)and L. sect. Sarcophyllum (for the Sudano‐Zambezian/Saharo‐Arabian clade); (c) themore expanded circumscription of L. sect. Nephrophyllum (including species of the L.bellidifolium complex); and (d) the new combinations for L. sect. Pruinosum and L. sect.Pteroclados subsect. Odontolepideae and subsect. Nobiles.
