Laurent s.n., Butala is an accession record for a pressed herbarium specimen of Cannabis sativa collected at Butala, in what is now the Democratic Republic of the Congo and was then the Congo Free State, on 18 November 1903 by M. Laurent. Meise Botanic Garden holds the sheet as catalogue BR0000014662713.[1] GBIF publishes the gathering as preserved specimen occurrence 1839971872.[2] The sheet carries no collector number, so it is titled by collector, locality and year.
Collection and locality
The sheet bears the printed Mission Em. et M. LAURENT label of 1903-1904 and is dated 18 November 1903 in manuscript.[3] It belongs to the Laurent collections of 1903 and 1904, the period stamped on the accompanying Brussels slip of the companion sheet Laurent s.n., Manglié (1903).
Specimen and identification
The sheet is annotated with the symbol for a female plant, so the mounted material is pistillate.[3] The determination Cannabis sativa L. was confirmed on the Brussels slip in January 1945.[3][1]
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 SAMEA112694963 on 20 April 2024; it gives the voucher as BR<BEL>:14662713, 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 BR, one of a set organised under an umbrella project called Population Dynamics in Cannabaceae.[5] One whole-genome sequencing run from it, made on an Illumina NovaSeq 6000, was released on 21 July 2024.[6]
