Wisteria Nutt, 1818 (Leguminosae, Papilionoideae) includes about five or six living species, disjunctly distributed in the temperate regions of oft-com:office:smarttags" />China, Japan, and the USA. The fossil record indicates that this genus might have widely occurred in the Czech Republic, Holland, Georgian Abkhazia, Bulgaria, Romania, Russian Far East, Japan, and China since the Neogene. Therefore, the fossil record of Wisteria, especially its pod fossils, can provide useful data for a better understanding of its early evolution, taxonomy, diversity, paleoecology and biogeography. The pods were likely matured with twisted valves when brought into the lake by short distance transportation, and the valves returned to a flat state after soaking in the lake, and then were buried by the sediments and finally fossilized. oft-com:office:office" />
