Cananga
Cananga is a genus of two fragrant-flowered Annonaceae trees, including Cananga odorata (ylang-ylang), native from tropical Asia to northern Australia and cultivated for ylang-ylang essential oil used in perfumery and food flavoring.
Cananga odorata
Cananga odorata (ylang-ylang, ilang-ilang), an Annonaceae tree native from southern Indo-China to Queensland, grown in tropical plantations for ylang-ylang and cananga essential oils used in perfumery and soap.
Canarina
Canarina is a small genus of flowering plants in the bellflower family, with three species disjunctly distributed between the Canary Islands and the mountains of East Africa.
Canarium
Canarium L. is a genus of about 120 dioecious tropical trees in Burseraceae, native from tropical Africa to the western Pacific; includes pili nut (C. ovatum), canarium nut (C. indicum), and Manila elemi (C. luzonicum), distinct from the mollusc genus Canarium Schumacher, 1817.

Cannabis
Cannabis (marijuana, hemp; Cannabis sativa L.) is a Cannabaceae genus domesticated in East Asia about 12,000 years ago, debated as one or several species, defined by THC content, and now partly legalized and reclassified medically.
Cannabis indica
Cannabis indica, named by Lamarck in 1785 from Indian specimens, is a contested cannabis taxon now usually treated as C. sativa subsp. indica or subsumed into a monotypic, highly diverse species; vernacular indica labels do not reliably predict chemistry.
Cannabis ruderalis
Cannabis ruderalis Janisch., a putative third cannabis species described by Janischevsky in 1924, now usually a synonym of Cannabis sativa; source of the day-neutral autoflowering trait via Autoflower1/Autoflower2 loci.
Cannabis sativa
Cannabis sativa (hemp, marijuana) is an herbaceous annual Cannabaceae crop domesticated in Central Asia ~12,000 years ago; cannabinoids like THC and CBD are made in female-flower trichomes, and the 0.3% THC threshold legally separates hemp from marijuana.
