Evidentiary scope

The label reads Waste ground near docks., under FLORA OF DURBAN, with the collection line Coll. W.E. Evans 2.10.1917. The plant grew on waste ground beside a working port. Ruderal cannabis at a dock is as likely to have come off a ship as out of the hinterland, and the label says nothing either way. The accession is classified Feral, by inference from the label; the label does not say whether the plants descended from a crop. A single gathering does not establish a continuing population, and no conservation priority is assigned.

Georeferencing

The label reads Waste ground near docks. under FLORA OF DURBAN. The point -29.88, 31.03 is the middle of the Port of Durban's land, OpenStreetMap way 511713340 (landuse harbour, about 8.5 km²); its farthest edge is 3.8 km from the middle, and 1 km is added for the rounding of the point. It is an area point for the docks, not the patch of waste ground, and the docks of 1917 were smaller than the port mapped today. An earlier version of this note gave no point because no catalogue or label gives a coordinate. Basis: settlement point. Uncertainty: about 5 km.

Editorial treatment

Edinburgh's catalogue records no collector, number, date or country for this sheet. It files it under the region Southern Africa and nothing more. Every value this accession carries is transcribed from the digitised sheet, and that transcription is what the accession rests on.

The date is read as 2 October 1917 on the British convention the label's other content implies. The label writes 2.10.1917.

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

Source discrepancies

The Royal Botanic Garden Edinburgh publishes two licences for this image. Its IIIF manifest states CC BY-SA 2.5 with attribution required; the Darwin Core record and GBIF's media block state CC0. The file page follows the manifest, which is the herbarium's own statement about the image rather than about the data, as the wiki's earlier Edinburgh file pages do.
