We are witnessing the rapid disappearance of traditional cultivation knowledge and genetic diversity in cannabis. These landrace populations represent thousands of years of natural and human selection, containing unique genetic traits and chemical profiles. Systematic documentation and conservation efforts can serve as a bridge—preserving irreplaceable genetic heritage while supporting traditional communities and advancing our understanding of this remarkable plant.

Bokeo #2 General Population 2022 is a landrace cannabis accession collected at point of origin by the Real Seed Company in Bokeo, northwestern Laos in 2022.
Cannabis taxonomy
Cannabis taxonomy is the classification of plants in the genus Cannabis within the family Cannabaceae. The taxonomy of the genus has been disputed since the eighteenth century and remains unresolved. Three principal treatments coexist in the modern literature: a monotypic concept in which the genus contains a single polymorphic species, Cannabis sativa L.; a two-species concept in which Cannabis indica Lam. is treated as a separate species; and a three-species concept in which a further species, Cannabis ruderalis Janisch., is also recognised.
The dispute is further compounded by a vernacular nomenclature, drawn from the late-twentieth-century drug trade, in which the labels "Sativa" and "Indica" came to be applied to plants in ways that do not correspond to the formal scientific epithets of the same names. McPartland and Guy described this divergence in 2017, after a survey of herbarium specimens and primary descriptions and showed that the vernacular and formal taxonomies refer to substantially different sets of plants.
Forty years of intentional hybridisation between drug-type populations from different geographic origins, combined with prohibition-era barriers to systematic study, has left the taxonomy of the modern commercial accession landscape only loosely resolved. Conservation taxonomy of pre-hybridisation source populations is a distinct and active line of work, most fully developed in the four-variety treatment of landrace populations proposed by McPartland and Small in 2020. read more →
