Medicago sect Dendrotelis includes shrubby perennial plants which produce stipitate pods with 1-3 coils, flowers with the keel equalling or slightly longer than the standard, and embryos with the radicle about half as long as seed. Three taxa with Mediterranean distributions are known: M. arborea, M. citrina and M. strasseri. The tetraploid number 2n = 32 is reported for M. strasseri, and the lectotype of M. citrina, a taxon for which the species rank is accepted, is also designated. Diagnostic characters, ecology and distribution areas are commented for all of them. Conservation remarks on M. citrina are reported. Finally, an identification key is also presented.
