Evidentiary scope
The catalogue gives a collector, a number, a date and a locality. It is a single gathering and shows neither a continuing population nor a living germplasm holding, so it supports neither a landrace nor a feral classification. The accession is classified Other. 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 coordinate is the centre of a quarter-degree square, not a field fix. BODATSA records the accuracy as 1/4dg and stores the square's code alongside it; a quarter-degree square is about 27 km across. 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. On Éloïse's ruling of 23 September 2026 the point is carried, at the precision the database gives it, with the accuracy stated here. BODATSA's LatLongChecked field is null on every Cannabis row, so no coordinate in this batch has been verified by the herbarium.
The square is 2528CA.
Editorial treatment
The gathering is filed at Pretoria because PRE's entry is the dated one and the date it gives is internally consistent.
Source discrepancies
PRE dates this gathering 11 April 1920 and NH dates the same collector and number 1973. The accession carries PRE's date, which is the day-precise one and the one consistent with Kathleen Annie Lansdell's working life; NH's is recorded here and is not adopted. A specimen date that sits half a century after a sibling sheet is usually an accession or registration date. Both sheets need to be seen.
The same collector's number 630, at Barberton, is a separate undated accession.
