Page scope

Flanagan 607 (1891) 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 holds two sheets of this gathering, made at Komgha in February 1891, and their locality strings differ: one reads KOMGHA; WASTE GROUND and the other KOMGHA; ABOUT HOMESTEADS AND OLD KRAAL (around homesteads and an old livestock enclosure). Both place the plants on disturbed ground outside cultivation. The accession is classified Feral, by inference from the catalogue; the catalogue 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.

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 3227DB.

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.

Source discrepancies

The two sheets carry different locality strings for one gathering, WASTE GROUND on PRE0372455-0 and ABOUT HOMESTEADS AND OLD KRAAL on PRE0372451-0. Both are quoted in the article and neither is preferred. Henry George Flanagan collected at Komgha in the eastern Cape from the 1880s; the Selmar Schonland Herbarium at Makhanda holds much of his material and may hold a third sheet. That herbarium has no public catalogue.
