Description
Decades of cannabis prohibition have created major gaps in our understanding of cannabis biology, especially with regard to the genomic, phenotypic, and germplasm resources that are standard in other agriculturally and medicinally important crops. Herbarium collections, which serve as archival specimens that preserve plant material for long term study, are no exception. Although herbarium specimens are meant to document plant diversity, most collections contain only a narrow sampling of cannabis and do not reflect the extensive variation present in commerce or this species at large. To address this need, the Canndor Herbarium was established in 2016 as the first dedicated cannabis herbarium, providing a lasting repository for the taxonomic, genetic, and morphological diversity of cultivars and landraces within the species. To illustrate the exceptionally broad diversity of cannabis, we present a case study using herbarium vouchers collected from 2017 through 2022 to investigate natural variation in leaf morphology. Digitized specimens were analyzed with image analysis tools to quantify fifteen traits related to leaf shape and color. We also highlight the expanding utility of the herbarium for studies that rely on accurate cultivar identification. This includes its essential role in confirming clonal identity for field and greenhouse experiments, where ensuring that plants are true to type is critical for reproducible results, meaningful comparisons across studies, and enforcement of material transfer agreements. By integrating physical vouchers with genomic and phenomic data, this work establishes a robust framework for cataloging, verifying, and preserving cannabis diversity. This resource strengthens research reproducibility, supports cultivar identity standards, and advances future crop improvement as the scientific and legal landscape for cannabis continues to evolve.

Comments
Nick Batora is Managing Director and Head of Research and Development at LeafWorks Inc., a botanical genomics and diagnostics company focused on DNA based identity, authenticity, and quality testing for botanicals, foods, and natural products. He leads the development and validation of molecular assays including qPCR, next generation sequencing, and quantitative metagenomics for species identification, adulteration detection, and microbial analysis. Nick earned his PhD studying the ecological and genetic mechanisms underlying phytochemical evolution in Passiflora incarnata. His academic background in plant secondary metabolism and evolutionary biology informs his current work translating genomic technologies into practical, defensible analytical tools. He collaborates closely with industry partners, contract laboratories, and standards organizations to advance method validation, reference database curation, and reproducible frameworks for botanical testing.
