It has been a general assumption by botanists who have not worked taxonomically on the genus that Cannabis is monotypic. The preponderance of literature has treated it as such in the absence of any thorough taxonomic review to establish whether the epithet sativa must be restricted to a single morphologically distinct taxon within a more variable genus than presupposed or whether the specimens and literature concerning Cannabis permit the recognition of more than one specific epithet, in… Expand

Models of Cannabis Taxonomy, Cultural Bias, and Conflicts between Scientific and Vernacular Names
TLDR
The development of vernacular “Sativa,’ “Indica,” and “Ruderalis” was abetted by twentieth century botanists, who ignored original protologues and harbored their own cultural biases. Expand

Chemotyping and Determination of Antimicrobial, Insecticidal, and Cytotoxic Properties of Wild-Grown Cannabis sativa from Nepal
TLDR
The essential oil from Nepalese Cannabis sativa was screened for antimicrobial, cytotoxic, larvicidal, and insecticidal activity, and it appears as though C. sativa is relatively non-toxic. Expand
