Linnaeus first categorised Cannabis as a monotypic genus in 1753, and indeed many states still legislate on the assumption that there is only one species, Cannabis sativa.
However, in 1783, Lamarck contrasted C. sativa with a separate distinct species, which he proposed be named C. indica.
Since then up to a dozen different species of cannabis have been proposed, many by Russian botanists early in the 20th century.
Nowadys botanical thinking is of the opinion that the cannabis genus contains three species, C. sativa, indica and ruderalis. The latter contains no THC however, and is of little interest to us.
