We present in this paper a molecular phylogeny of the genus Moricandia<\/em> (Brassicaceae). We have found that a Spanish population previously ascribed to Rytidocarpus moricandioides<\/em> is indeed a Moricandia<\/em> species, and we propose to name it as M. rytidocarpoides<\/em> sp. nov. In addition, M. foleyi<\/em> appeared outside the Moricandia<\/em> lineage but within the genus Eruca<\/em>. Therefore, M. foleyi<\/em> should be excluded from the genus Moricandia<\/em> and be ascribed to the genus Eruca<\/em>.<\/p>\n

The phylogeny of tribe Brassiceae (Brassicaceae) has not yet been resolved because of its complex evolutionary history. This tribe comprises economically relevant species, including the genus Moricandia<\/em> DC. This genus is currently distributed in North Africa, Middle East, Central Asia and Southern Europe, where it is associated with arid and semi-arid environments. Although some species of Moricandia<\/em> have been used in several phylogenetic studies, the phylogeny of this genus is not well established.<\/p>\n

Here we present a phylogenetic analysis of the genus Moricandia<\/em> using a nuclear (the internal transcribed spacers of the ribosomal DNA) and two plastidial regions (parts of the NADH dehydrogenase subunit F gene and the trnT-trnF region). We also included in the analyses members of their sister genus Rytidocarpus<\/em> and from the close genus Eruca<\/em>.<\/p>\n

The phylogenetic analyses showed a clear and robust phylogeny of the genus Moricandia<\/em>. The Bayesian inference tree was concordant with the maximum likelihood and timing trees, with the plastidial and nuclear trees showing only minor discrepancies. The genus Moricandia<\/em> appears to be formed by two main lineages: the Iberian clade including three species, and the African clade including the four species inhabiting the Southern Mediterranean regions plus M. arvensis.<\/em><\/p>\n

We dated the main evolutionary events of this genus, showing that the origin of the Iberian clade probably occurred after a range expansion during the Messinian period, between 7.25 and 5.33 Ma. In that period, an extensive African-Iberian floral and faunal interchange occurred due to the existence of land bridges between Africa and Europa in what is, at present-days, the Strait of Gibraltar. We have demonstrated that a Spanish population previously ascribed to Rytidocarpus moricandioides<\/em> is indeed a Moricandia<\/em> species, and we propose to name it as M. rytidocarpoides<\/em> sp. nov. In addition, in all the phylogenetic analyses, M. foleyi<\/em> appeared outside the Moricandia lineage but within the genus Eruca. Therefore, M. foleyi<\/em> should be excluded from the genus Moricandia<\/em> and be ascribed, at least provisionally, to the genus Eruca<\/em>.<\/p>\n<\/div>\n
