Why the area is on the map
- Bon 2113 (1883): the collector's label reads 2113 (H.N.) Lan Mát, 10 Maii 1883. (Cult.), for a male plant named Gai = Cannabis.
- Bon s.n., Lan Mát (1884): the collector's slip reads Cannabis sativa (cult.) and Lan Mát 17 Juin 1884.
- Two gatherings a year apart, by one collector, at one place, both marked cultivated. No other source read places cannabis growing at Lan Mát.
Growing status
The status is Historical: the evidence is the two sheets of 1883 and 1884, and nothing read says either that growing continued or that it ended. The infobox carries no years of growing, because no source other than the sheets gives a year, and the sheets' dates show in their own row.
Where Lan Mát is
No gazetteer consulted places Lan Mát, and the labels give no collection point, so neither sheet carries coordinates. What the labels and other sources say:
- Bon's other labels use the name for a mountain or a group of mountains (in montibus Lan Mat, in monte Lan Mat), and one of his 1884 labels reads Monts entre Lan Mat et Lat Son. Lạt Sơn lies in the former Kim Bảng district of Hà Nam.
- The abbreviation (H.N.) on the 1883 label is not expanded there; Bon's other labels read prov. Ha Nam. Hà Nam was merged into Ninh Bình Province on 16 June 2025, which is the province both accessions and this page carry.
- Bon's collections are cited from his mission station Kẻ Sở (Ke So, im Gebirge Kiên Khê, in a protologue by Engler and Gehrmann as quoted on Aroidpedia). Kẻ Sở is the Sở Kiện basilica at Kiện Khê, in the former Thanh Liêm district of Hà Nam.
- A hamlet named La Mát (thôn La Mát) belongs to Kiện Khê, according to a description of the Châu pagoda and the Phúc Long cave in the Kiện Khê hills. That La Mát is Bon's Lan Mát is probable but not established, and the article does not say so.
How the border is drawn
- The border is a proxy, drawn on one administrative unit: the former Thanh Liêm district of Hà Nam (OpenStreetMap historic boundary relation 7121553, the district as it stood until 30 June 2025), about 166 km², the figure in the infobox rounded.
- The district holds Kiện Khê, the seat both of Bon's station and of the La Mát hamlet. Lạt Sơn lies outside it, in the former Kim Bảng district, so the mountains named on Bon's labels may extend beyond the border.
- The coordinates in the infobox are a point inside the proxy, not a place on either label.
- The border is not drawn from accession points; neither accession has coordinates.
The name
The page takes the name as Bon's labels spell it, Lan Mát. The museum's catalogue writes Lan Mat and Lan mat, without the accent.
Sources
Both sheets were read from the museum's full-resolution scans. The catalogue entries (GBIF occurrences 731718319 and 731719484) were re-checked on 19 October 2026: collector Bon, H.F., dates 10 May 1883 and 17 June 1884, localities Tonkin, Lan Mat and Lan mat. Searches in Vietnamese for Lan Mát as a mountain or village in Hà Nam found only the La Mát hamlet above.
