**Marijuana Flower** is cannabis, a dioecious herb with distinctive leaves that can have 5 to 13 serrated leaflets. The leaf arrangement varies, with lower leaves opposite and upper leaves alternate.
Cannabis leaves feature a unique venation pattern, allowing easy differentiation from similar species. Each serration has a central vein, which branches off into spur veins near the notches.
Cannabis is primarily wind-pollinated. Most strains are short-day plants, while some varieties, like *C. ruderalis*, are auto-flowering or day-neutral.
Cannabis predominantly has separate male and female plants. Male flowers grow on loose panicles, while females form racemes. Monoecious varieties can produce both flower types on the same plant, but true hermaphrodites are rare.
Intensive cultivation has led to various sexual phenotypes, with dioecious varieties preferred for drug and fiber production. Monoecious types are often used for pulp and paper. Understanding these characteristics helps differentiate between legal hemp and illicit cannabis.
