Cannabis was among the to start with plant species to become karyotyped; even so, this was in a interval when karyotype preparing was primitive by fashionable specifications (see Heritage of Cytogenetics). Heteromorphic sex chromosomes had been noted to happen in staminate people today of dioecious "Kentucky" hemp, but were not found in pistillate folks of precisely the same range.

The title Cannabis indica was detailed in a variety of Pharmacopoeias, and helpful hints was commonly accustomed to designate Cannabis ideal for the manufacture of medicinal preparations.[62] 20th century
