The internal and external transcribed spacers of 53 Medicago species sensu stricto and 10 of the 23 medicagoid species were sequenced. Both maximum parsimony or maximum likelihood criterion joined medicagoid species more confidently with Medicago rather than with Trigonella. The basal position of the medicagoid species within the genus Medicago, together with morphologically atypical Medicago species (such as M. radiata and M. platycarpa), raised the question of the expediency to define a new group and/or a new genus and is discussed, relatively to the support of each clade, based on morphological and molecular data. Using criteria of monophyly and support, it was concluded that the medicagoids are better joined in Medicago rather than placed in a new genus.} }
