Cannabis () is a genus of flowering plants that includes three different species, Cannabis sativa , Cannabis indica and Cannabis ruderalis .

They have wide, deeply serrated leaves and a compact and dense flower cluster.

Cannabis sativa

Resin, in the most specific meaning of the term, is a hydrocarbon secretion of many plants, particularly coniferous trees.

Additional Cannabis species were proposed in the 19th century, including strains from China and Vietnam (Indo China) assigned the names Cannabis chinensis Delile, and Cannabis gigantea Delile ex Vilmorin.

Examples of resin acids are abietic acid (sylvic acid), C20H30O2, plicatic acid contained in cedar, and pimaric acid, C20H30O2, a constituent of galipot resin.

This venation pattern varies slightly among varieties, but in general it enables one to tell Cannabis leaves from superficially similar leaves without difficulty and without special equipment.

It is improbable, however, that the production of amber was limited to a single species and indeed a large number of conifers belonging to different genera are represented in the amber flora.

Tiny samples of Cannabis plants also can be identified with precision by microscopic examination of leaf cells and similar features, but that requires special expertise and equipment.

Since the early 1970s, Cannabis plants have been categorized by their chemical phenotype or chemotype, based on the overall amount of THC produced, and on the ratio of THC to CBD.

In the early 20th century, the single species concept was still widely accepted, except in the Soviet Union where Cannabis continued to be the subject of active taxonomic study.

Early classifications The Cannabis genus was first classified using the modern system of taxonomic nomenclature by Carolus Linnaeus in 1753, who devised the system still in use for the naming of species.
