Mesembryanthemum Caudatum
''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.

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 ...

Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Code Of Botanical Nomenclature
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embryo
An embryo is an initial stage of development of a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell. The resulting fusion of these two cells produces a single-celled zygote that undergoes many cell divisions that produce cells known as blastomeres. The blastomeres are arranged as a solid ball that when reaching a certain size, called a morula, takes in fluid to create a cavity called a blastocoel. The structure is then termed a blastula, or a blastocyst in mammals. The mammalian blastocyst hatches before implantating into the endometrial lining of the womb. Once implanted the embryo will continue its development through the next stages of gastrulation, neurulation, and organogenesis. Gastrulation is the formation of the three germ layers that will form all of the different parts of the body. Neurulation forms the ner ...

Pistil
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) '' pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the " female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens ar ...

Johann Jacob Dillenius
Johann Jacob Dillen Dillenius (1684 – 2 April 1747) was a German botanist. He is known for his ''Hortus Elthamensis'' ("Eltham Garden") on the rare plants around Eltham, London, and for his ''Historia muscorum'' ("History of Mosses"), a natural history of lower plants including mosses, liverworts, hornworts, lycopods, algae, lichens and fungi. Biography Dillenius was born at Darmstadt and was educated at the University of Giessen, earlier the family name had been changed from Dillen to Dillenius. In 1721, at the instance of the botanist William Sherard (1659–1728), he moved to England. In 1734 Dillenius was appointed Sherardian professor of botany at Oxford, in accordance with the will of Sherard, who at his death in 1728 left the university £3000 for the endowment of the chair, as well as his library and herbarium, all on the condition that Dillenius should be appointed the first professor. Dillenius died at Oxford, of apoplexy. His manuscripts, books and collections ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
