Evidentiary scope

The catalogue records the collector T. Naude, the date 23 April 1968 and the locality PETRONELLA; OP WERF OP PLOT VAN MNR. VENTER (Afrikaans for on the yard on Mr Venter's plot). No image of the label is published. The locality gives a position and says nothing about habitat, use or cultivation, so nothing shows whether the plant was cultivated, grew wild or had escaped. The accession is classified Unknown. 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 -25.5, 28.116667 is the one the herbarium database, BODATSA, publishes for this sheet. BODATSA gives its accuracy, 1dg, one degree, which is about 110 km, and nonetheless stores the quarter-degree code 2528CA against the entry, so the two fields disagree about how well the gathering is placed; the stated accuracy is the one carried. The database's locality, PETRONELLA; OP WERF OP PLOT VAN MNR. VENTER, names a smallholding at Petronella. The only Petronella in OpenStreetMap is a railway stop (node 408994502), 13.9 km east of the point; a stop is not shown to be the smallholding, so it is not used. Basis: holder's georeference. Uncertainty: about 110 km.

Editorial treatment

BODATSA writes a PRE accession number into the collector-number field of this entry. PRE 52593 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 locality is in Afrikaans and is quoted rather than translated in the locality field; the article gives an English rendering alongside it.
