Mesembryanthemum Decurvatum
''Mesembryanthemum'' is a genus of flowering plants in the family Aizoaceae, indigenous to southern Africa. As with many members of that 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. 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 that term refers to many plants in the family Aizoaceae. Species formerly placed in ''Mesembryanthemum'' have been transferred to other genera, such as ''Cleretum'' and ''Carpobr ...

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 herb Herbs are a widely distributed and widespread group of plants, excluding vegetables, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances.

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'' mainly occurs in the sandy coastal habitats of mild Mediterranean climates, and can be also found inland in sandy to marshy places. In general, members of this genus prefer open sandy spaces where their wiry, long roots with shorter side branches form dense underground network. The root networks typically extend much further than the above-ground prostrate branches. Plants thrive well in gardens, but readily escape to other suitable locations, resulting in some members of the genus being considered an invasive sp ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

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 ...

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. History of psychoactive plants Many plants contain substances that alter moods and cause euphoria. Some of these psychoactive plants were known to the ancients. The history of poppy cultivation dates back to 3400 BC. In Mesopotamia. Po ...

Invasive Weed
An invasive species is an introduced species that harms its new environment. 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 web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide. 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 invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade. Notable invasive plant species include the kudzu vine, giant hogweed (''Heracleum mantegazzianum''), Japanese knotweed (''Re ...

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 all 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raphide
Raphides ( ; singular ''raphide'' or ''raphis'') are needle-shaped crystals of calcium oxalate monohydrate ( prismatic monoclinic crystals) or calcium carbonate as aragonite ( dipyramidal orthorhombic crystals), found in more than 200 families of plants. Both ends are needle-like, but raphides tend to be blunt at one end and sharp at the other. Calcium oxalate in plants Many plants accumulate calcium oxalate crystals in response to surplus calcium, which is found throughout the natural environment. The crystals are produced in a variety of shapes. The crystal morphology depends on the taxonomic group of the plant. In one study of over 100 species, it was found that calcium oxalate accounted for 6.3% of plant dry weight. Crystal morphology and the distribution of raphides (in roots or leaves or tubers etc.) is similar in some taxa but different in others leaving possible opportunities for plant key characteristics and systematic identification; mucilage in raphide containi ...

International Code Of Botanical Nomenclature
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) 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. For fungi the ''Code'' was revised by the ''San Juan Chapter F'' in 2018. The 2025 edition of ICBN, the '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embryo
An embryo ( ) is the initial stage of development for 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 (4-cell stage) are arranged as a solid ball that when reaching a certain size, called a morula, (16-cell stage) 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistil
Gynoecium (; ; : gynoecia) 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 (botany), whorl of a flower; it consists of (one or more) ''#Pistil, pistils'' and is typically surrounded by the pollen-producing plant reproductive morphology, 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, Marchantiophyta, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridiu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
