Of the approximately 1,000 seed plant species examined, the Lupine species and the California croton seeds had the most similar appearances to the marijuana (cannabis sativa) seeds, with the seeds of Humulus (hop seeds), being the closest relative to C. sativa. The results of this research benefits members of forensic science and botany communities in regards to the physical identification and appearance comparison of marijuana seeds. Within the forensic science literature, as well as the botanical literature, there is little documentation concerning the identification of marijuana seeds. This study was conducted to create a visual standard and basis for the comparison and identification of seeds of C. sativa based on their appearance. References and appendixes A-D
