The genus Cannabis has had a long association with man and contains considerable variation in growth form, achene size, and chemical content. The variation has taxonomically been variously interpreted. Some maintain the genus is polytypic with at least three species (Emboden, 1974; Schultes et al., 1974). Others (Small and Cronquist, 1976) believe that it is properly viewed as monotypic: i.e. limited to C. sativa L. They do, however, recognize several infraspecific varieties. Historical aspects…

TLDR
A scoping review of recent literature regarding the phylogenetics of Cannabis, descending the taxonomic ranks of family, genus, species, subspecies, and varieties shows that Italy has been a crossroads of Cannabis fiber-type plant genotypes, between Europe and Asia.
Cannabis Systematics at the Levels of Family, Genus, and Species
TLDR
DNA barcode analysis supports the separation of these taxa at a subspecies level, and recognizing the formal nomenclature of C. sativa and C. indica, and genetic drift in this population likely initiated allopatric differences between European Cannabis sativa (cannabidiol [CBD]] and Asian Cannabis indica (THC>CBD).
Genomic and Chemical Diversity in Cannabis
TLDR
A combined analysis of population genomic and trait variation informs the understanding of the potential uses of different genetic variants for medicine and agriculture, providing valuable insights and tools for a rapidly emerging valuable industry.

TLDR
There are 4 basic preparations of marijuana: bhang, hasish, oil (or hash oil), and leaves and/or buds, and most strains’ names do not follow the rules.
Host-Parasite Relationships in Cannabis
TLDR
It is suggested that certain parasites may have co-evolved with putative species and biotypes within the Cannabisgenus.
Patterns of diversity in Cannabis
SummaryA Cannabis germplasm collection was evaluated for traits relevant to the use of hemp as an arable source of paper pulp. The traits were related to stem yield and quality, psychoactive potency,
Vegetative growth of Cannabis sativa L. cultivars in Jamaica using 18/6 photoperiod
TLDR
C cultivating sativa type cultivars in Jamaica and tropical regions may require less energy input in a shorter time frame to achieve greater biomass output during the vegetative cycle, which may give rise to the possibility of harvesting greater yields with less inputs for the Tropical Ganja Farmer.
Genetic evidence for speciation in Cannabis (Cannabaceae)

  • 2003
TLDR
A polytypic concept of Cannabis is proposed, which recognizes three species, C. indica and C. ruderalis, and seven putative taxa, and none of the previous taxonomic concepts that were tested adequately circumscribe the sativa and indica gene pools.

TLDR
Cannabis has been associated with man since very early times, yet, surprisingly, little is known about its comparative wood anatomy, except for details of seedling anatomy and floral structure.
Flavonoid variation in Cannabis L.
TLDR
The distribution of compounds supported the subspecific treatment of the genus suggested by Small & Cronquist (1976), but the data were less helpful in resolving trends amongst the varieties recognized by those authors.
