There are seven records related to the plant Qi(杞)in Shi Jing(《诗经》Classic Of Poems).The existence of different objects with the same name complicates its overall classification and specific meanings,and various scholars also have disagreeing opinions.In a comprehensive view,Qi(杞)in Shi Jing can refer to three categories of plants:firstly as Gou Qi(枸杞Lycium chinense Miller)in Si Mu(《四牧》Four Horses),Zhan Lu(《湛露》Heavy Dew)and Si Yue(《四月》the Fourth Month);secondly as Han Liu(旱柳Salix matsudana Koidz.)in Qiang Zhong Zi(《将仲子》A Man Named Zhong Zi);and thirdly as Feng Yang(枫杨Pterocarya stenoptera C.DC.)seen in Nan Shan You Tai(《南山有台》A Plant on South Mountain),Di Du(《杕杜》Lonely Tree)and Bei Shan(《北山》North Mountain).The Ju(榉)in Ming Yi Bie Lu(《名医别录》Additional Entries from a Famous Doctor)is actually Feng Yang(枫杨Pterocarya stenoptera C.DC.),but Zhong Guo Zhi Wu Zhi(《中国植物志》Flora of China)mistakenly interprets it as Ju Shu[榉树Zelkova serrata(Thunb.)Makino].
