Evans s.n., Durban docks is a herbarium accession of Cannabis sativa collected at Durban in KwaZulu-Natal, South Africa, on 2 October 1917 by W. E. Evans. The Royal Botanic Garden Edinburgh holds the sheet as E01459337.[1][2] The gathering exists in no catalogue: Edinburgh records nothing about the sheet beyond its filing region, and everything here was read from the sheet itself.
The label
The sheet carries a printed Edinburgh label headed HERB. HORT. BOT. REG. EDIN. and, beneath it, FLORA OF DURBAN. The determination Cannabis sativa is written by hand. The locality reads Waste ground near docks. and the collection line reads Coll. W.E. Evans 2.10.1917. A pencilled 153 is circled at the right.[2]
What the catalogue holds
Edinburgh's catalogue records no collector, number, date or country for this sheet. It files it under the region Southern Africa and nothing more. Every value this accession carries was read from the digitised sheet in September 2026, and the reading is what the accession rests on.[1]
