Evidentiary scope
The catalogue records the collector E. N. Vos, the date September 1957 and the locality Tvl. Potchefstroom Dist. (Tvl. standing for Transvaal). No image of the label is published, so the label cannot be read, and the catalogue says nothing about how or where the plant grew. The accession is classified Unknown until the label can be read. No conservation priority is assigned.
The Botanical Database of Southern Africa publishes no image of this sheet. Its image count is zero, and so is the image count of all 1,361,966 rows in the database: the store is empty, and SANBI's own site still lists plant images among its plans. The accession carries no image until the herbarium supplies a scan.
Georeferencing
No point is given. The database gives the locality as Tvl. Potchefstroom Dist., the magisterial district of the Transvaal in 1957, and no place within it. no source read gives the district's bounds in 1957, and today's units around Potchefstroom are not shown to be the same area, so a district point with an honest radius cannot be given. The town of Potchefstroom lies in North West, the province the page states. An earlier version of this note gave no point only because the herbarium database carries no coordinate for the sheet.
Editorial treatment
This entry is in SANBI's own POSA front end but not in the BODATSA feed that reaches GBIF, so a GBIF sweep misses it. Ten of the Compton Herbarium's fifteen Cannabis entries are in that position, against five that the feed carries. Every one was checked against GBIF by catalogue number and returned no match.
BODATSA publishes no per-specimen page, so the accession cites the database and the barcode identifies the sheet.
The month and year stand without a day, and none is supplied.
The catalogue places the gathering in Gauteng, but Potchefstroom is in North West province. The district was in the Transvaal when the sheet was made, and the province fields of these older entries follow the modern boundaries imperfectly. The province field carries North West, the province of the town the district is named for, and not the catalogue's Gauteng.
