The flowers are 8–15 cm in diameter. The flower base color can be white, yellow, or purple, and the white and yellow flowers are dark purple in ...
Leaves are often more or less palmately lobed or palmately compound and always bear stipules. Cystoliths are always present and some members of this family possess laticifers. Cannabaceae are often dioecious (distinct male and female plants). The flowers are actinomorphic (radially symmetrical) and not showy, as these plants are pollinated by ...
Cannabis plants vary widely, with different strains producing dynamic balances of cannabinoids (THC, CBD, etc.) and yielding markedly different effects. Popular strains are often hybrids of C. sativa and C. indica. The medicinal effects of cannabis are widely studied, and are active topics of research both at universities and private research ...
Cannabis ruderalis is a variety, subspecies, or species of Cannabis native to Central and Eastern Europe and Russia. It contains a relatively low quantity of psychoactive compound tetrahydrocannabinol (THC) and does not require photoperiod to blossom (unlike C. indica and C. sativa ).
