Why the area is on the map
- Li and colleagues (2026), Table S1: three of their twenty hemp landraces, collected in 2020, come from Muli (CZ27) and Huili (CZ39) in Liangshan and from Yanbian (CZ21) in Panzhihua.
- Wang and colleagues (2026): a feral population of ten plants from Zhaojue County.
- The Panzhihua heritage listing of 2020: the Miao of Yanbian sow hemp seed every June for their cloth.
- Yanbian joins the area because it has a landrace of its own and the Miao weaving, and lies next to Liangshan.
Growing status
The status is Active: the landrace seed was collected in 2020, and the Yanbian listing of 2020 describes the sowing as a living craft. The Zhaojue population was published in 2026, with no collection date in the paper.
How the border is drawn
- The border follows Liangshan Yi Autonomous Prefecture (relation 2785750) and Yanbian County of Panzhihua (2785688), Sichuan, China, as mapped in OpenStreetMap (read 22 October 2026). It stops at the Yunnan provincial line.
- Miyi County of Panzhihua is not one of the units, but they surround it, so its ground (about 2,100 km²) is inside the border. The city districts of Panzhihua, on the Yunnan line, are outside.
- The elevation and land-cover rules used for other hubs (the ridges round the valleys that hold land below 4,000 m, with the high ground of valleys that have none left out at the edge) take out less than 0.5% of the units, so apart from Miyi the border is the units' own line.
- Check points inside the border: Xichang, the collecting point of Yu 1220, Huidong, Leibo, Yanyuan, Muli. Outside it: central Panzhihua, Lijiang, Kunming.
- Where this border meets Yunnan, Kham, Lijiang or Dêqên, the two share one line.

The name
The page takes the name of the prefecture, Liangshan (凉山). The article uses "Yi" for the people the older Western travellers called "Lolo"; that word appears on the page only if attributed.
The landraces
Li and colleagues call their twenty lots landraces and give each one's origin by county. They are lots of hemp achenes, which the paper says are valued for food and medicine, gathered for a study of their chemistry; the paper does not describe the fields they came from. The article attributes both the word and the origins to the paper.
Zhaojue in the 2026 table
Wang and colleagues print an altitude of 520 m for the Zhaojue site (28.01° N, 102.85° E). Zhaojue County lies on a high plateau, far above 520 m, so the figure is probably an error of the table; the article gives it as printed and attributes it.
Accessions inside the border
Yu 1220 (1932), from Xichang, is not filed under the area: it is classed as of unknown status, and its labels give the place and year but not where the plant grew.
Sources
- Li and colleagues (2026), Journal of Pharmaceutical Analysis: the paper and its Table S1.
- Wang and colleagues (2026), BMC Plant Biology, Table S1: population ZJ.
- The Yanbian listing: the description of the Miao weaving craft entered by the Panzhihua government on its fourth heritage list (3 July 2020), as published on a regional culture site. It says the cloth was first made of a wild fibre cut on the hills, which it calls 野生活麻; that name does not establish cannabis, and the article gives only the sowing of 火麻籽 (hemp seed).
- The Dechang report (Sichuan International Communication Centre, 2024): it names 火麻 (hemp) as a fibre of the cloth but does not say where the hemp is grown.
Sources not used
- E. Colborne Baber's account of his journey through the Yi country of Liangshan, published by the Royal Geographical Society in 1882, does not mention hemp. The page does not use it.
