Koelz 1666 is an accession record for a pressed herbarium specimen of Cannabis sativa collected by Walter Koelz beside a road at Keshapur, in the historical Punjab region of India, on 7 March 1931. The New York Botanical Garden holds the sheet as catalogue 1414440.[1] GBIF publishes it as occurrence 1927776378.[2]
Collection and locality
Koelz's Roerich Museum field label records Keshapur, a roadside habitat and an altitude of about 1,000 feet.[3] The altitude converts to approximately 305 m and is stored in the infobox. The label is headed Flora of Punjab, and the specimen databases place Keshapur in Punjab.[3][2] The exact modern location has not been established, so no present-day state, district or coordinate is asserted.
Field observations
The label describes a three-foot plant with staminate flowers.[3] Its roadside occurrence directly documents a ruderal plant, supporting the accession's feral classification. That setting does not determine whether the population descended from cultivated plants or represented a longer-established local population.
Specimen and identification
In August 1975, Ernest Small determined the specimen as Cannabis sativa var. kafiristanica (Vavilov) E.Small & Cronquist, the name under which GBIF publishes the occurrence.[3][2] Small and Arthur Cronquist subsequently cited Keshapur, Punjab, Koelz 1666 (NY) among the representative specimens for that variety. Their treatment grouped the variety with indigenous, weedy and naturalized plants, while recognizing that those histories cannot always be distinguished from morphology alone.[4]
Evidentiary limits
The sheet documents a roadside cannabis plant, its sex and approximate elevation. The 1975 determination and 1976 taxonomic treatment do not establish a named cultivated variety, population continuity or a living germplasm holding. The record therefore supports a feral classification but not a landrace classification. No conservation priority is assigned.
