Evidentiary scope
The labels give the place, the year, the collector and the expedition. They name no habitat, use or note on cultivation. The accession is classified Other and no conservation priority is assigned.
Label reading
Read twice, independently, from the Chinese Virtual Herbarium's image of each sheet (PE 00578008, 983 × 1,440 pixels; PE 00777007, 996 × 1,440 pixels).
- PE 00578008, West China form (printed 中國西部科學院植物標本室, typed): Fd. No. 1220 / Cannabis sativa Linn. / Collector T.T.Yu / Locality S.W. Szechuan / Det. by (dotted line, blank) / Date 1932. SZECHUAN province stamp; Fan Memorial Institute stamp; red 34355.
- PE 00777007, Peiping form (printed INSTITUTE OF BOTANY / NATIONAL ACADEMY OF PEIPING / FLORA OF CHINA, stamped): Field No. 1220 / Date 1932 / Locality 四川 西昌 / Collector 俞德浚. Determination slip: Cannabilis sativa L. / 定名人 (blank) / 72年4月12日. Stamped number 614823.
- Tag on both sheets (printed, number by hand): Szechuan Exp. / T.T.Yu 1932 / No. 1220.
The two readings agree.
- Chongqing sheet (CQNM 0001502), read twice, independently, from the Chinese Virtual Herbarium's image (CQNM 0001502, 2,000 × 2,806 pixels). Form (purple, filled in ink, simplified characters): 重庆市博物馆植物标本 (the characters 博物馆 faint) / 科名 桑科 / 学名 Cannabis sativa Linn. / 中名 大麻 / 产地 四川 / 采集人 俞德浚 / 标本室号数 (blank) / 采集号 1220 / 目录号 (blank) / 鉴定人 俞德浚 / 时期 1932年, the month and day blank. In ink above the form, underlined in red: Ee.1-7/06466. Tag (printed, mounted upside down): Szechuan Exp. / T.T.Yu 1932 / No. and a number in pencil, read as 1220 and as 12[?]8; a third look at the image fits 1220. Pencil 1220 on a paper flap; blue stamped number 02217. Barcode 重庆自然博物馆 (CQNM). The readings agree on the form, except that one takes the collector's and determiner's last character as 俊; a third look reads 浚 on both lines.
Georeferencing
西昌 is written in characters, so it is read directly as Xichang, today a county-level city of Liangshan, Sichuan, and the only county-level Xichang in the province (Wikidata Q224603). The label does not say whether it means the town or the county, so the county is taken. The point 27.86, 102.13 is the middle of Xichang's administrative area in OpenStreetMap (relation 2786746, about 2,898 km²), checked to fall inside it; the town's own place node lies about 14 km to the east-north-east. The present area is taken for the one the label names. It is an area point for the county, not the place the plant was gathered. Basis: district point. Uncertainty: about 31 km.
Editorial treatment
Three sheets, one accession. The sheets share the number, the year, the collector and the tag. The repository and catalogue number are PE 00578008's.
Collector. The collector field keeps the label's T. T. Yu. He is Yü Te-tsun (俞德浚, 1908–1986): the Harvard botanist index gives the name and dates and notes that he collected extensively in Yunnan and Sichuan, and Chinese Wikipedia gives T.T.Yu as his standard form. The prose links Yü Te-tsun.
Date. The labels give the year 1932 only, which is stored.
Image. The Chinese Virtual Herbarium publishes its images under CC BY-NC-ND 4.0, so the page cites each sheet's image and shows none.
The Chongqing form. The museum's form is in simplified characters, so it was written after the gathering, from the tag or another record; it adds no place below the province, no day and no habitat. It enters 俞德浚 as determiner as well as collector; the identified-by field stays empty, as nothing on the sheet shows when the name was determined or by whom beyond the form's entry.
Source discrepancies
- The catalogue names the collector of PE 00777007 as 俞德俊; the stamp on the sheet reads 俞德浚. It does the same for CQNM 0001502, whose form writes 俞德浚.
