Evidentiary scope

The catalogue records the collector R. Nkosi, the year 1934 with the month and day blank, and the locality AMERSFORT. 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

The point -27.125, 29.875 is the one the herbarium database, BODATSA, publishes for this sheet. It is the centre of the quarter-degree square 2729BB, 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 Amersfoort, which the label names (OpenStreetMap node 262694821), lies inside the square, 12.9 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 writes a PRE accession number into the collector-number field of this entry. PRE 27780 is the herbarium's own number for the sheet, not a number the collector gave the gathering, and the collector-number field carries it as the database has it. Nine Cannabis entries in BODATSA do the same.

The year stands alone: the database gives no month and no day, and none is supplied here.

The database spells the place AMERSFORT; the town in Mpumalanga is Amersfoort. The locality field uses the town's spelling and the article quotes the database's.
