Page scope

Codd 8505 (1954) 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 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. 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 Cannabis coordinate in BODATSA has been verified by the herbarium.

The square is 2528CA.

Editorial treatment

Codd made a second gathering at the same station four weeks later, Codd 8506, which is the female plant. Neither Pretoria nor Edinburgh records a sex in a field; the label's symbol is read here as male and the reading is stated as a reading.

Source discrepancies

Edinburgh publishes two licences for this image: the IIIF manifest says CC BY-SA 2.5 with required attribution, and the Darwin Core record and GBIF's media block say CC0. The file page follows the manifest, which is the herbarium's own statement about the image rather than about the data.

Pretoria's locality is PRETORIA DIST.; the Edinburgh label names the Prinshof Experiment Station. The locality field carries the station, because the label is the primary witness and the catalogue is a summary of it.
