[Continuity and changes of breeds of fupenzi].

Based on textual researches, it has been confirmed that Fupenzi first appeared in Han Dynasty. Both Fupenzi and Penglei had the same origin, but split up during Jin Dynasty into two different breeds. Through ages Fupenzi has been taken as the fruits of the plant Rubus of Rosaceae species. Among them, R. idaeus, R. corchorifolius and R. coreanus have long been in use. R. chingii is the new breed of modern Fupenzi.
