Chevalier 42218 is a herbarium accession of Cannabis sativa collected by Auguste Chevalier at Adrar, in the Touat of south-western Algeria and dated 31 December 1931. Its label states that the plant was cultivated. The Muséum national d’Histoire naturelle in Paris holds the sheet as catalogue P00957683.[1] GBIF publishes it as occurrence 1987025402.[2]
Collection and locality
Chevalier's printed label reads Aug. Chevalier., Plantes de l'Afrique Occidentale Française, with the last three words struck through and Territoires du Sud algérien written above them. In manuscript it gives no 42.218, the name, the date 31-12 1931, Adrar, cultivé and Coll. A. Chevalier.[3] The catalogue gives the locality as the single word Adrar, the field number as 42218 and the date as 31 December 1931. It leaves out the cultivation note.[1][2] No habitat or altitude is given.
Adrar is the largest settlement of the Touat oasis group, in the Algerian Sahara.[4] It lies in Adrar Province.[5]
Auguste Chevalier lived from 1873 to 1956, so a gathering of 1931 falls inside his working life.[6] He is also named as the determiner of the sheet.[1][2]
Specimen and identification
The sheet holds two leafy stems. The field label names the plant Cannabis sativa L. s. sp. C. indica L. The museum's label repeats the name. The sheet is headed Herbier Aug. Chevalier and stamped Ex herbier ethnobotanique.[3] The catalogue records the preparation as a herbarium sheet and the name as Cannabis sativa L.[1][2] One image of the sheet is published with the occurrence, credited to Fabrice Clermont and issued under a Creative Commons Attribution-NonCommercial-NoDerivatives licence, which is a narrower licence than the rest of the Algerian series carries.[2]
