[Display omitted] •The origin of the thorny cushion-like xerophytes from Astragalus sect. Tragacantha takes root in the middle of the Pliocene (4.4 Mya), between the Messinian salinity crisis and the onset of the Mediterranean climate.•The phylogeographic structuring of the section is based on an ol...
