Page scope

Van der Walt s.n., Skukuza (1981) is about a single collection of cannabis, a seed lot or a herbarium specimen: where and when it was gathered, by whom, and what the sources say about the plants.

Evidentiary scope

The catalogue records the collectors van der Walt and Potgieter, the date 15 December 1981, the locality Skukuza village., the vernacular name Dagga and the plant as Herb with digitate leaf, leaf margin strongly toothed. The leaf description says nothing about how the plant grew. No image of the label is published, and the catalogue records no habitat, use or note on cultivation. 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 -24.994722, 31.590278 is the one the Skukuza Herbarium publishes for this sheet. The 1985 gathering at the same camp gives exactly the same figures, to six decimal places. Two gatherings four years apart agreeing to the sixth decimal is a look-up on the place name, not two field readings. It lies 0.2 km from Skukuza Rest Camp in OpenStreetMap (node 262716119). The 2011 census gives Skukuza 4.98 km² (English Wikipedia, Skukuza), a circle about 1.3 km in radius, so the point places the gathering in the camp to within about 2 km and no closer. Basis: holder's georeference. Uncertainty: about 2 km.

Editorial treatment

The Skukuza Herbarium is a herbarium outside the usual list. It publishes 15,811 records to GBIF under CC BY-NC 4.0 and holds four Cannabis entries, two of which duplicate a Pretoria sheet and two of which, this and the 1985 one, are gatherings no other herbarium has.

Its entries are the only ones in the South African batch whose vernacular column is filled in. All four read Dagga.

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