Evidentiary scope
The database gives the locality as LICHTENBURG, the collector J. Burtt Davy, the number 56 and the date 18 March 1903. It records no habitat, use or note on cultivation, and the label has not been read, so nothing shows whether the plant was cultivated, grew wild or had escaped. 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
The point -26.125, 26.125 is the one the herbarium database, BODATSA, publishes for this sheet. It is the centre of the quarter-degree square 2626AA, about 27 km across, and not the place the plant was gathered: BODATSA gives its accuracy, 1/4dg, and stores the square's code beside it. Of the 61 georeferenced Cannabis rows in BODATSA, all 41 flagged 1/4dg fall exactly on a square's centre and none of the other 20 does. BODATSA's LatLongChecked field is null on every Cannabis row, so no Cannabis coordinate in BODATSA has been verified by the herbarium. The town of Lichtenburg, which the label names (OpenStreetMap node 262721003), lies inside the square, 4.4 km from the point. The point is carried at the precision the database gives it. Basis: holder's georeference. Uncertainty: about 19 km.
Editorial treatment
BODATSA publishes no per-specimen page: five permalink shapes were tried for a sheet and all answered 404. The accession cites the database itself, and the barcode identifies the sheet.
