Distribution: Old World (2400 spp.), esp. Iran (over 1000), Russia/Siberia (over 600), China (400), Turkey (450), Afghanistan (330), Kazakhstan (300), Tajikistan (234), Uzbekistan (223), Turkmenistan (132), Kyrgyzstan (161)), Mediterranean (> 150), secondary centers in North America (ca. 400), South American Andes (ca. 50-100), only few in montane tropical Africa. Old World revision see Podlech & Zarre (2013), New World Revision see Barneby (1974) and Welsh (FNA vol. 11/2, 2023) for North America. Astragalus remains the largest genus of plants without apomictic microspecies.
