Evidentiary scope
The label places cannabis on a littered patch of the Onon floodplain in July 1990. It gives no use and no note on cultivation. The determination as Cannabis ruderalis is the botanist's judgement from the specimen and is reported as such. A single gathering does not establish a landrace or a continuing population. The accession is classified Other and no conservation priority is assigned.
Label reading
Read twice, independently, from the holder's image (3693 × 5206 pixels). The page states only what the readings agree.

Georeferencing
The point 49.455739, 112.45639 is the one the herbarium's database publishes for this sheet, with an uncertainty of 4 km. It lies in Bayan-Uul sum, Dornod, by the Onon near the Russian border, and the red dot on the label's printed map, at about 112.5° E, 49.5° N, agrees with it. SRTM gives 829 m; the label gives no altitude. Basis: holder's georeference. Uncertainty: about 4 km.
Editorial treatment
Determiners. The label brackets both names against Собр. and Опред. (collected, determined), and the article names both; the identified-by field takes the first, as the collector field does.
Place names. Bayan-Ula is Bayan-Uul, the Dornod sum centre on the road; Verkhniy Ulkhun is the Russian village across the border. The label's road is the one between them; the page does not name the border post.
Source discrepancies
- The database files the sheet as Cannabis sativa L.; the label's determination is Cannabis ruderalis Janisch.
- The database gives no collector number or locality and names one collector; the label gives № 291, the Onon floodplain and two collectors.
