Evidentiary scope

The database gives the date as 9 August 1935, the collector as D. Hesom and the locality as Estcourt District. and nothing finer. It records no habitat, use or note on cultivation, and no image of the label is published, so nothing shows whether the plant was cultivated, grew wild or had escaped. The accession is classified Unknown, and 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 -29.125, 29.875 is the one the herbarium database, BODATSA, publishes for this sheet. It is the centre of the quarter-degree square 2929BB, 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 label names the district, not a place in it. The town of Estcourt (OpenStreetMap node 95831525) lies inside the square, 12.7 km from the point; the district's bounds in 1935 are not read here. The point is carried at the precision the database gives it. Basis: holder's georeference. Uncertainty: about 19 km.

Editorial treatment

The KwaZulu-Natal Herbarium publishes no per-specimen page. Five permalink shapes were tried for a sheet and all answered 404, so the accession cites the database itself and the barcode identifies the sheet.

The gathering has no collector's number, so the title follows the Algeria precedent for a numberless sheet with a named collector and a place.
