Evidentiary scope

The sheet carries a printed label headed FLORA OF S. AFRICA. with the collector's number 1401 for Rev. F. A. Rogers, the place written by hand as Johannesburg and the date Feb, 1909. The label records a city and nothing about the setting: no habitat, use or note on cultivation. Nothing shows whether the plant was cultivated, grew wild or had escaped, so the accession is classified Unknown. No conservation priority is assigned.

Georeferencing

The point -26.21844, 28.041622 is the one the University of Zurich herbarium publishes for this sheet. The label names Johannesburg and no more, so the point is a look-up on the city's name and not a field reading: it lies 1.6 km from the city's point on English Wikipedia (Johannesburg). The 2011 census gives the city 334.81 km², a circle about 10.3 km in radius, and the 1.6 km between the two points is added. It places the gathering in Johannesburg, not at a spot within it. Basis: holder's georeference. Uncertainty: about 12 km.

Editorial treatment

The image carries no licence at Zurich or at GBIF, and is used under a fair-use rationale. A licence request would settle it.

The collector's herbarium was bought by Zurich in 1930 and the sheet was accessioned in 1932, twenty-three years after the gathering. Neither date is a collection date.
