Mesembryanthemum Guerichianum Seedling IMG 8167-cropped
''Mesembryanthemum'' is a genus of flowering plants in the family Aizoaceae; like many members of this family, it is characterized by long-lasting flower heads. Flowers of ''Mesembryanthemum'' protect their gametes from night-time dews or frosts but open in sunlight. There is an obvious evolutionary advantage to doing this; where sun, dew, frost, wind or predators are likely to damage exposed reproductive organs, closing may be advantageous during times when flowers are unlikely to attract pollinators. It is indigenous to southern Africa. Many ''Mesembryanthemum'' species are known as ice plants because of the glistening globular bladder cells covering their stems, fruit and leaves, "... they sparkle like ice crystals". In South Africa, Mesembryanthemums are known as "vygies" (from Afrikaans "vy"), although this term refers to many plants in the family Aizoaceae. Species formerly placed in ''Mesembryanthemum'' have been transferred to other genera, such as ''Cleretum'', '' Carpob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesembryanthemum Nodiflorum
''Mesembryanthemum nodiflorum'' is a species of succulent plant in the genus ''Mesembryanthemum'' known by the common name slenderleaf iceplant. It is the type species for the genus. It is native to coastal areas of the Mediterranean Basin, Macaronesia, and Middle East but it is known in many other places as an introduced species and sometimes an invasive weed, including several regions of Australia, parts of the western United States and adjacent Mexico, and some Atlantic islands. ''M. nodiflorum'' is a usually annual Annual may refer to: *Annual publication, periodical publications appearing regularly once per year ** Yearbook ** Literary annual *Annual plant *Annual report *Annual giving *Annual, Morocco, a settlement in northeastern Morocco *Annuals (band), ... herb forming a mostly prostrate clump or mat of stems up to a maximum of about 20 centimeters in length.

Carpobrotus
''Carpobrotus'', commonly known as pigface, ice plant, sour fig, Hottentot fig, and clawberry is a genus of ground-creeping plants with succulent leaves and large daisy-like flowers. The name comes from the Ancient Greek ' "fruit" and ' "edible", referring to its edible fruits. The genus includes some 12 to 20 accepted species. Most are endemic to South Africa, but there are at least four Australian species and one South American. Distribution and habitat ''Carpobrotus'' chiefly inhabits sandy coastal habitats in mild Mediterranean climates, and can be also found inland in sandy to marshy places. In general, they prefer open sandy spaces where their wiry, long roots with shorter side branches form dense underground network, which extends much further than above-ground prostrate branches. Plants thrive well in gardens, but can easily escape to other suitable places. They easily form wide-area ground covers over a sandy soil, which easily suppresses indigenous sand dune vegetation ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America). It is maintained by the Missouri Botanical Garden and was established over 25 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louisiana State Act 159
Signed into law June 28, 2005, and effective August 8, 2005, Louisiana State Act No 159 found in, Louisiana RS 40:989.1, outlawed the cultivation, possession or sale of 40 named plants defined as hallucinogenic in the state of Louisiana, US. House Bill 173 of 2010 further restricted the sale and possession of herbs in the state. However, use of the plants "strictly for aesthetic, landscaping, or decorative purposes" was allowed. The list contained as many as thirty legitimate herbs of commerce which had no hallucinogenic properties. The law was amended in 2015 to allow certain herbs that had been banned by the state to again be sold in dietary supplement products. Plants The following were declared to be "hallucinogenic plants" by the bill: *''Amanita muscaria'' (a fungus, not a plant) *''Anadenanthera colubrina'' *''Anadenanthera peregrina'' *''Atropa belladonna'' *''Banisteriopsis'' spp. *''Brugmansia arborea'' *''Brunfelsia'' spp. *''Calea zacatechichi'' *'' Conocybe'' spp. (a ...

Hallucinogenic Plants
Psychoactive plants are plants, or preparations thereof, that upon ingestion induce psychotropic effects. As stated in a reference work: Psychoactivity may include sedative, stimulant, euphoric, deliriant, and hallucinogenic effects. Several hundred psychoactive plants are known. Some popular examples of psychoactive plants include '' Coffea arabica'' (coffee), '' Camellia sinensis'' (tea), ''Nicotiana tabacum'' (tobacco), and ''Cannabis'' (including hashish). Psychoactive plants have been used ritually (''e.g.'', peyote as an entheogen), medicinally (''e.g.'', opium as an analgesic), and therapeutically (''e.g.'', cannabis as a drug) for thousands of years. Hence, the sociocultural and economic significance of psychoactive plants is enormous. Examples of psychoactive plants In the table below, a few examples of significant psychoactive plants and their effects are shown. For further examples, see List of psychoactive plants.

Invasive Weed
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...
