Evidentiary scope

The database gives the date as 7 October 1975, the collector C. S. Dixon and the locality Stellenbosch Dist. Assegaaibosch. 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 database names Stellenbosch Dist. Assegaaibosch., the Assegaaibosch Nature Reserve in the Jonkershoek valley, and no place within it. OpenStreetMap does not map the reserve's outline; the point -33.97, 18.92 is the reserve's picnic site, OpenStreetMap node 1553909555, inside it. English Wikipedia (Assegaaibosch Nature Reserve) gives the reserve's area as 204 hectares, a circle about 0.8 km in radius, and 1 km is added for the rounding of the point. It is a point for the reserve, not the place the plant was gathered. An earlier version of this note gave no point because the database publishes no coordinate for the sheet. Basis: settlement point. Uncertainty: about 2 km.

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.
