Yu 1220 is a herbarium accession of Cannabis sativa collected at Sichang (西昌, Xichang), in south-western Sichuan, China, in 1932 by T. T. Yu on the Szechuan Expedition. The Institute of Botany, Chinese Academy of Sciences in Beijing holds two sheets, PE 00578008[1] and PE 00777007[2], and the Chongqing Natural History Museum a third as CQNM 0001502.[3]

PE 00578008 carries a typed form of the herbarium of the Science Institute of West China (中國西部科學院植物標本室): Fd. No. 1220, the collector T.T.Yu, the locality S.W. Szechuan and the date 1932. PE 00777007 carries a Flora of China form of the Institute of Botany, National Academy of Peiping, completed with stamps: the number 1220, the year 1932, the locality 四川 西昌 (Szechwan, Sichang) and the collector 俞德浚 (Yü Te-tsun). Both sheets carry the same printed tag, Szechuan Exp., T.T.Yu 1932 and No. 1220.[4][5] The catalogue gives the number, the year and Sichuan, with the collector as T. T. Yu for one sheet and 俞德俊 for the other.[1][2] CQNM 0001502 carries the same tag and a later form of the Chongqing Municipal Museum (重庆市博物馆), written in simplified characters, which gives the number 1220, the year 1932, the province 四川 (Szechwan) and 俞德浚 as collector and as determiner.[6] The catalogue gives that sheet's collector as 俞德俊.[3]
