Koelz 692 is an accession record for a pressed herbarium specimen of Cannabis sativa collected by Walter Koelz at Sisu, now generally written Sissu, in Lahaul and Spiti District, Himachal Pradesh, India, on 25 July 1930. The New York Botanical Garden holds the sheet as catalogue 1414432.[1] GBIF publishes it as preserved specimen occurrence 1929949596.[2]
Collection and locality
Koelz completed an Urusvati Himalayan Research Institute field label headed Flora of Lahul. It gives his collection number 692, the locality Sisu, the habitat Door yard, an altitude of 10,000 feet and the date 25 July 1930.[3] The stated altitude converts to 3,048 m.
Field observations
The field label records the common name Bhang and describes the plant as 6½ feet tall, with flowers yellowish green, envelope tinged with purple.[3] Its special notes read Roasted seeds eaten and leaves smoked as drug, with also cultivated added in pencil.[3]
Specimen and identification
The original labels identify the specimen as Cannabis sativa L. In August 1975, Ernest Small determined it as Cannabis sativa subsp. indica (Lam.) E.Small & Cronquist, the name under which GBIF publishes the occurrence.[3][2] The mounted material is fruiting and preserves roots, stems, leaves and inflorescences.[3]
Sequence data
Leaflets from this sheet were sampled for DNA by a herbarium-genomics project coordinated by Christopher J. Grassa of Harvard University, and the sample was sequenced by Marco Todesco at the University of British Columbia. The European Nucleotide Archive made it public as BioSample SAMEA112688672 on 24 February 2025; it gives the voucher as NY:1414432, this sheet, and the tissue as Leaflets removed from original specimen voucher.[4]
The sample belongs to the archive's project DNA sequencing of Cannabis specimens accessioned in herbarium NY, one of a set organised under an umbrella project called Population Dynamics in Cannabaceae.[5] Two whole-genome sequencing runs from it, made on an Illumina NovaSeq 6000, were released on 20 April 2025.[6][7]
