Vavilov s.n., Gui-Akhen is a herbarium accession of Cannabis sativa grown from seed that Nikolai Vavilov collected in 1924 at the village of Gui-Akhen on the road from Ghazni to Kandahar, Afghanistan. The plant was raised from that seed in 1926 at an experiment station in Russia. The specimen is held by the herbarium of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (WIR), and in 2020 John McPartland and Ernest Small designated it the neotype of Cannabis sativa subsp. indica var. afghanica.[1][2]
Collection and locality
The seed came from Gui-Akhen village near Qala-i Murvardar, on the road between Ghazni and Kandahar, in present-day Ghazni Province, formerly part of Kandahar Province. Vavilov collected it in 1924, and the plant was grown from seed sown by Serebriakova in 1926 at North Caucasus Experiment Station, Maikop, Krasnodar Krai. The sheet is labelled Cannabis sativa and carries the WIR numbers 609 and 3945.[1]
A second sheet from the same seed lot is also at WIR: Gui-Akhen, Vavilov, 1924, reprod. by Serebriakova in 1925 at Kamenno-Stepnaya Exp. Station, Voronezh Oblast, labelled Cannabis sativa, WIR 609, 7380.[3]
The Missouri Botanical Garden's Tropicos database, as GBIF publishes it, gives the same locality and seed history, the collector N. I. Vavilov, the year 1924 and the province Ghazni, and files the specimen under Cannabis sativa f. afghanica Vavilov.[2]
Typification
McPartland and Small raised Vavilov's Cannabis sativa f. afghanica, published in 1926, to a variety of subsp. indica, which they call the Central Asian domesticate. They state that no original specimen survives for the name: no specimen labelled afghanica exists at WIR, and the achene illustration in Vavilov and Bukinich (1929) cannot serve as a lectotype because it is not part of the 1926 protologue. They therefore designated this specimen the neotype, and designated Schultes 26505, collected near Kandahar in December 1971, as an epitype explicitly supporting it.[1]
Specimen and identification
The paper's photograph of the neotype shows a single pressed branch with large, long-fingered leaves and small flower clusters along its upper stem.[1] The specimen is labelled Cannabis sativa; its name as a type is Cannabis sativa subsp. indica var. afghanica (Vavilov) McPartl. & E.Small.
