Page scope

Killick 1692 (1952) 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 gives the locality as BERGVILLE DIST.; CATHEDRAL PEAK FOR.; ON TERRACE IN FRONT OF COTTAGE ON LITTLEBERG and the date as 28 February 1952, and records nothing else about how the plant grew. The page reads the locality as ground in front of a cottage, a dooryard setting rather than a stand. The catalogue does not say whether the plant was grown there or came up by itself, so 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 -29.125, 29.375 is the one the herbarium database, BODATSA, publishes for this sheet. It is the centre of the quarter-degree square 2929AB, 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 label names Bergville District, not a place in it. The town of Bergville (OpenStreetMap way 302243775) lies about 44 km north of the point, outside the square; the district's bounds in 1952 are not read here. The point is carried at the precision the database gives it. Basis: holder's georeference. Uncertainty: about 19 km.

Editorial treatment

BODATSA publishes no per-specimen page: five permalink shapes were tried for a sheet and all answered 404. The accession cites the database itself, and the barcode identifies the sheet.
