Stroganowia tiehmii, discovered in Nevada by Arnold Tiehm and his associates, is the only New World member of this otherwise central Asiatic genus. The disjunction evident in Stroganowia is an extreme case. Other genera of the Cruciferae show several patterns of disjunction but their geographical distributions also point to a definite relationsip between the floras of central Asia and interior western North America.
