indigenous to Central Asia, and South Asia. Found worldwide.

Physical Description
Cannabis is an annual, dioecious, flowering herb. The leaves are palmately compound or digitate, with serrate leaflets. The first pair of leaves usually have a single leaflet, the number gradually increasing up to a maximum of about thirteen leaflets per leaf (usually seven or nine), depending on variety and growing conditions. At the top of a flowering plant, this number again diminishes to a single leaflet per leaf. The lower leaf pairs usually occur in an opposite leaf arrangement and the upper leaf pairs in an alternate arrangement on the main stem of a mature plant.
Cannabis has been described as having one of the most complicated mechanisms of sex determination among the dioecious plants. Many models have been proposed to explain sex determination in Cannabis.
Environmental sex determination is known to occur in a variety of species. Some scientists have found that treatment with auxin and ethylene have feminizing effects, and that treatment with cytokinins and gibberellins have masculinizing effects.

General Information

The genus Cannabis was formerly placed in the Nettle (Urticaceae) or Mulberry (Moraceae) family, but is now considered along with hops (Humulus sp.) to belong to the Hemp family (Cannabaceae).
Various types of Cannabis have been described, and classified as species, subspecies, or varieties:
* plants cultivated for fiber and seed production, described as low-intoxicant, non-drug, or fiber types.

* plants cultivated for drug production, described as high-intoxicant or drug types.

* escaped or wild forms of either of the above types.

"Cannabis" comes from the word, "Canvas".

Cannabis indica

Cannabis ruderalis

"Sativa" is the term used to describe the most widespread variety, which is usually tall, laxly branched, and found in warm lowland regions. "Indica" is used to designate shorter, bushier plants adapted to cooler climates and highland environments. "Ruderalis" is the term used to describe the short plants that grow wild in Europe and central Asia.

Cannabis normally has imperfect flowers, with staminate "male" and pistillate "female" flowers occurring on separate plants.[10] It is not unusual, however, for individual plants to bear both male and female flowers.[11] Although monoecious plants are often referred to as "hermaphrodites," true hermaphrodites (which are less common) bear staminate and pistillate structures on individual flowers, whereas monoecious plants bear male and female flowers at different locations on the same plant. Male flowers are normally borne on loose panicles, and female flowers are borne on racemes. "At a very early period the Chinese recognized the Cannabis plant as dioecious," and the (ca. 3rd century BCE) Erya dictionary defined xi "male cannabis" and fu "female cannabis".
All known strains of Cannabis are wind-pollinated and produce "seeds" that are technically called achenes. Most strains of Cannabis are short day plants, with the possible exception of C. sativa , which is commonly described as "auto-flowering" and may be day-neutral.
Cannabis, like many organisms, is diploid, having a chromosome complement of 2n=20, although polyploid individuals have been artificially produced. The plant is believed to have originated in the mountainous regions northwest of the Himalayas. It is also known as hemp, although this term is often used to refer only to varieties of Cannabis cultivated for non-drug use. Cannabis plants produce a group of chemicals called cannabinoids, which produce mental and physical effects when consumed. Cannabinoids, terpenoids, and other compounds are secreted by glandular trichomes that occur most abundantly on the floral calyxes and bracts of female plants. As a drug it usually comes in the form of dried flower buds (marijuana), resin (hashish), or various extracts collectively known as hashish oil. In the early 20th century, it became illegal in most of the world to cultivate or possess Cannabis for drug purposes.
