It is also known as hemp, although this term is often used to refer only to varieties of Cannabis cultivated for non-drug use. ruderalis), which is commonly described as "auto-flowering" and may be day-neutral. In the 1970s, the taxonomic classification of Cannabis took on added significance in North America. Indica designates shorter, bushier plants adapted to cooler climates and highland environments.Cannabis normally has imperfect flowers, with staminate "male" and pistillate "female" flowers occurring on separate plants. Cannabis plants produce a group of chemicals called cannabinoids, which produce mental and physical effects when consumed. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. Laws prohibiting Cannabis in the United States and Canada specifically named products of C. Enterprising attorneys for the defense in a few drug busts argued that the seized Cannabis material may not have been C. Attorneys on both sides recruited botanists to provide expert testimony. Ruderalis is the informal name for the short plants that grow wild in Europe and central Asia.
Male flowers are normally borne on loose panicles, and female flowers are borne on racemes. The genus Cannabis was formerly placed in the Nettle (Urticaceae) or Mulberry (Moraceae) family, and later, along with the Humulus genus (hops), in a separate family, the Hemp family (Cannabaceae sensu stricto). In the United States alone, it is believed that over 100 million Americans have tried cannabis, with 25 million Americans having used it within the past year.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. as a wild or escaped variety of low-intoxicant Cannabis, and C. Professors William Emboden, Loran Anderson, and Harvard botanist Richard E. sativa is tall and laxly branched with relatively narrow leaflets, C.At the top of a flowering plant, this number again diminishes to a single leaflet per leaf. Schultes and coworkers also conducted taxonomic studies of Cannabis in the 1970s, and concluded that stable morphological differences exist that support recognition of at least three species, C. indica is shorter, conical in shape, and has relatively wide leaflets, and C.In 1785, noted evolutionary biologist Jean-Baptiste de Lamarck published a description of a second species of Cannabis, which he named Cannabis indica Lam. However, many taxonomists found these putative species difficult to distinguish. In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. Many countries regulate limits for psychoactive compound (THC) concentrations in products labeled as hemp.Lamarck based his description of the newly named species on plant specimens collected in India. In the early 20th century, the single-species concept was still widely accepted, except in the Soviet Union where Cannabis continued to be the subject of active taxonomic study. Janichevsky concluded that ruderal Cannabis in central Russia is either a variety of C. Cannabis for industrial uses is valuable in tens of thousands of commercial products, especially as fibre ranging from paper, cordage, construction material and textiles in general, to clothing. It also is a useful source of foodstuffs (hemp milk, hemp seed, hemp oil) and biofuels.I have been clean for over 4years and am involved in recovery.
