Molecular Biogeography of Tribe Thermopsideae (Leguminosae): A Madrean-Tethyan Disjunction Pattern with an African Origin of Core Genistoides

Figure 3

Scheme of dispersal routes from the biogeographical S-DIVA analysis, Figure 2. The blue dashed line indicates the origin center of core genistoides from Africa (elliptic 1), arriving in Central Asia (elliptic 2), which was the place of origin of the Thermopsideae; then there was a dispersal to North America. Routes are shown by green dashed lines. From Central Asia (elliptic 2), a dispersal westward via the Caucasus to the Mediterranean with genus Anagyris and dispersal and adaptive radiation to QTP (elliptic 3), from QTP to North China, are shown by yellow dashed lines. Dispersal from North America at about late Miocene eastward to East Asia and Mediterranean is shown by red lines.
