| <p>The Botany portal documents plant identification, morphology, voucher specimens, ecology, phytochemistry, and field methods. Standards include diagnostic photography requirements and complete metadata protocols for scientific credibility.</p> | | <p>'''Cannabis botany''' examines the plant biology of ''Cannabis sativa'' L., covering morphology, physiology, reproductive biology, chemical ecology and environmental adaptation. As one of humanity's oldest cultivated plants, cannabis exhibits remarkable diversity in growth patterns, chemical profiles and ecological adaptations across traditional growing regions.</p> |

|
| <p><b>Key areas:</b> Species documentation, regional floras, herbarium vouchers, field photography standards, morphological terminology, and identification workflows.</p> | | <p>Cannabis is a [[Dioecy|dioecious]] annual herb in the family [[Cannabaceae]], characterized by palmate leaves with serrated leaflets, pistillate and staminate flowers on separate plants and dense resinous [[Trichome types|trichomes]] producing [[Cannabinoid profiles|cannabinoids]] and [[Terpene profiles|terpenes]]. The species shows extraordinary morphological variation, from compact highland varieties adapted to short growing seasons to tall tropical cultivars flowering under equatorial photoperiods.</p> |
| | |
| | <p>Key botanical themes include [[Photoperiod response|photoperiod response]] and flowering triggers, [[Trichome development|trichome development]] and [[Resin|resin]] production, [[Phenotypic plasticity|phenotypic plasticity]] and [[Climate adaptation in cannabis|climate adaptation]], life cycle [[Phenology|phenology]] across climates and the relationship between environmental conditions and [[Chemotype|chemical profiles]].</p> |

These specialized epidermal structures feature a multicellular stalk topped by a secretory head composed of disc cells that synthesize and accumulate cannabinoids, terpenes and flavonoids in a subcuticular storage cavity. Trichome density varies dramatically between [[Landrace cannabis|landrace]] populations, correlating with environmental pressures such as UV radiation intensity, [[Herbivory and defence|herbivory]] pressure and water stress.</p> |
| <li>[[Help:Botany page standards|Species page guidelines]] – Documentation structure and completeness standards</li> | | |
| </ul> | | <p>Highland varieties from regions like the Hindu Kush and Western Himalayas often display exceptionally dense trichome coverage with high [[Resin|resin]] production, reflecting [[Climate adaptation in cannabis|adaptation]] to intense solar radiation at high elevations. Lowland tropical varieties may show sparser but larger trichomes optimized for different environmental conditions. The chemical profile of trichome secretions also varies regionally: some populations produce predominantly THC, others CBD, while many landrace varieties maintain balanced [[Cannabinoid profiles|cannabinoid ratios]] reflecting thousands of years of selection for traditional uses.</p> |
