Why the area is on the map

• Cai and colleagues (2026): the wild accession CSLZ, from mother plants collected in "Linzhi County, Tibet" at an average altitude of 3,100 m, at 94.397312° E, 29.617220° N.
• Wang and colleagues (2026): the population LZ, ten plants from "Nyingchi City, Xizang Province" at 2,949 m, 29.6549° N, 94.3676° E, called feral in the paper's table.
• Police notices: Lilong border police station (June 2021), about 170 wild plants by an idle field; Baji village, Bayi town (September 2026), wild cannabis found by schoolchildren and cleared.
• Ludlow 15714 (1947), from dry open ground at Shoga Dzong.

Growing status

The status is Active: the LZ plants were collected on 10 May 2020 (the date in their NCBI sample entries), the CSLZ paper was published in 2026; the police notices date from 2021 and 2026. All of these describe wild or feral plants; no source dated 2000 or later describes a field crop in the area.

How the border is drawn

• The border follows three units of Nyingchi, Tibet, China, as mapped in OpenStreetMap (read 22 October 2026): Bayi District (relation 2734503), Mainling (2734500) and Gongbo'gyamda County (2734499). It lies inside the Southeastern Tibet border.
• In the south it stops at the frontier with India (Arunachal Pradesh) as OpenStreetMap maps it. Where the Eastern Himalayas border reaches the frontier, the two share one line; where that border's coarser line stops short of it, the narrow strip between is Indian ground as OpenStreetMap maps it and is inside neither border.
• The outer edge follows the ridges round the valleys that hold land below 4,000 m (SRTM elevation): each such valley is taken whole, up to the divide round it. Valleys with no such land, where the ground is above 4,000 m or is mapped by ESA WorldCover 2021 as bare or sparse vegetation, snow and ice, or open water, are left out at the edge; land of those kinds inside the kept ground stays inside. This takes out about 13,000 km² of the 31,000 km² of the units: the high plateau and the eastern Nyainqêntanglha ranges of western Gongbo'gyamda, the ranges north of Bayi, and the summit ground of Namcha Barwa.
• Check points inside the border: Bayi, Mainling, Gongbo'gyamda, the collecting point of Ludlow 15714. Outside it: Bomê, Mêdog, Lhasa.
• Where this border meets Southeastern Tibet or the Eastern Himalayas, the two share one line.
• Land cover: ESA WorldCover 2021 (version 200, 10 m), © ESA WorldCover project 2021 / Contains modified Copernicus Sentinel data (2021) processed by ESA WorldCover consortium, licensed CC BY 4.0. Elevation: AWS Terrain Tiles (Terrarium, SRTM-based), zoom 10.

The name

• Kingdon Ward (1926) and F. M. Bailey write "Kongbo"; the title is spelled "Kongpo". The Chinese form is 工布 (Gōngbù), as in Gongbo'gyamda (工布江达).
• "Linzhi" is the pinyin of Nyingchi (林芝). The "Linzhi County" of Cai and colleagues is the former county that is now Bayi District; their coordinates fall there. Wang and colleagues write only "Nyingchi City", which is the whole prefecture-level city; their coordinates also fall in Bayi District.

Accessions inside the border

• Filed under the area and the region: Ludlow 15714 (1947), classed as feral. Its label gives "Shoga Dzong" and the altitude, 10,500 feet; the coordinates on its page are a settlement point.

Where the sources disagree

• Wild or feral. Cai and colleagues call CSLZ a wild accession; Wang and colleagues call their Nyingchi plants feral. The two papers sampled different plants; the article keeps each paper's word.
• Lilong. The 2021 notice names only the Lilong (里龙) border police station of Nyingchi, not a township or county. Lilong is a township of Mainling.

Sources

• Cai and colleagues (2026), Horticulture Research 13 (9): the methods section gives the source of the CSLZ cuttings.
• Wang and colleagues (2026), BMC Plant Biology, published on 7 September 2026 as an accepted manuscript without volume or page numbers: Table S1 of the supplement gives each population's place, altitude, coordinates and status. The collection, identification and DNA extraction were done by the Institute of Forensic Science of the Ministry of Public Security.
• Police notices: China News (26 June 2021) for Lilong; the Nyingchi government website, reposting the Tibet Business Daily (30 September 2026), for Baji village. The Baji notice gives no count.
• Herbarium sheet: the Naturalis Bioportal entry for the Leiden sheet L.1592632.
