The Plant List includes 14 scientific plant names of species rank for the genus Cannabis. Of these 1 are accepted species names.
The Plant List includes a further 20 scientific plant names of infraspecific rank for the genus Cannabis. We do not intend The Plant List to be complete for names of infraspecific rank. These are primarily included because names of species rank are synonyms of accepted infraspecific names.
