Butomus Junceus
''Butomus'' is the only known genus in the plant family Butomaceae, native to Europe and Asia. It is considered invasive in some parts of the United States. Taxonomy The Butomaceae family has been recognized by most taxonomists as a plant family; it is sometimes called the "flowering-rush family". The APG II system, of 2003 (unchanged from the APG system, 1998), also recognizes such a family, and places it in the order Alismatales, in the clade monocots. At the ranks of family and order, this is the same placement as in the Cronquist system. However, Cronquist assumed a much smaller order and assigned the order to subclass Alismatidae, in class Liliopsida monocotyledons Species The family counts one species, ''Butomus umbellatus'', or two according to some authorities. *'' Butomus junceus'' (synonym ''Butomus umbellatus'' var.

Butomus Umbellatus
''Butomus umbellatus'' is a Eurasian plant species in the family Butomaceae. It is the only species in the family. Common names include flowering rush or grass rush. Introduced into North America as an ornamental plant it has now become a serious invasive weed in the Great Lakes area and in parts of the Pacific Northwest. In Israel, one of its native countries, it is an endangered species due to the habitat loss. It can also be found in Great Britain locally, for example at the Caldicot and Wentloog Levels. The plant is a rhizomatous, hairless, perennial aquatic plant. Its name is derived from Greek ''bous'', meaning "cow", "ox" etc. and ''tome'', a cut (the verb 'temnein' meaning "to cut"), which refers to the plant's swordlike leaves. Description In contrast to what its English name suggests, it is not a true rush. It is native to Old World continents and grows on the margins of still and slowly moving water down to a depth of about 3 m. It has pink flowers. The plant has ...

Rank (botany)
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a ''taxon'') in a hierarchy that reflects evolutionary relationships. Thus, the most inclusive clades (such as Eukarya and Animalia) have the highest ranks, whereas the least inclusive ones (such as ''Homo sapiens'' or '' Bufo bufo'') have the lowest ranks. Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, family, order, class, phylum, kingdom, and domain designate rank. This page emphasizes absolute ranks and the rank-based codes (the Zoological Code, the Botanical Code, the Code for Cultivated Plants, the Prokaryotic Code, and thCode for Viruses require them. However, absolute ranks are not r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Middle East
The Middle East (term originally coined in English language) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage by the United Kingdom and western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai Peninsula, Sinai) and all of Turkey (including East Thrace). Most Middle Eastern countries (13 out of 18) are part of the Arab world. The list of Middle Eastern countries by population, most populous countries in the region are Egypt, Turkey, and Iran, whil ...

Indian Subcontinent
The Indian subcontinent is a physiographic region of Asia below the Himalayas which projects into the Indian Ocean between the Bay of Bengal to the east and the Arabian Sea to the west. It is now divided between Bangladesh, India, and Pakistan. (subscription required) Although the terms "Indian subcontinent" and "South Asia" are often also used interchangeably to denote a wider region which includes, in addition, Bhutan, the Maldives, Nepal and Sri Lanka, the "Indian subcontinent" is more of a geophysical term, whereas "South Asia" is more geopolitical. "South Asia" frequently also includes Afghanistan, which is not considered part of the subcontinent even in extended usage.Jim Norwine & Alfonso González, ''The Third World: states of mind and being'', pages 209, Taylor & Francis, 1988, Quote: ""The term "South Asia" also signifies the Indian Subcontinent""Raj S.

Central Asia
Central Asia is a region of Asia consisting of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The countries as a group are also colloquially referred to as the "-stans" as all have names ending with the Persian language, Persian suffix "-stan" (meaning ) in both respective native languages and most other languages. The region is bounded by the Caspian Sea to the southwest, European Russia to the northwest, China and Mongolia to the east, Afghanistan and Iran to the south, and Siberia to the north. Together, the five Central Asian countries have a total population of around million. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians, and the semi-nomadic Scythians and Dahae. As the result of Turkic migration, Central Asia also became the homeland for the Kazakhs, Kyrgyzs, Volga Tatars, Tatars, Turkmens, ...

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 ...

Liliopsida
Liliopsida Batsch (synonym: Liliatae) is a botanical name for the class containing the family Liliaceae (or Lily Family). It is considered synonymous (or nearly synonymous) with the name monocotyledon. Publication of the name is credited to Scopoli (in 1760): see author citation (botany). This name is formed by replacing the termination ''-aceae'' in the name Liliaceae by the termination ''-opsida'' (Art 16 of the ICBN). Although in principle it is true that circumscription of this class will vary with the taxonomic system being used, in practice this name is very strongly linked to the Cronquist system, and the allied Takhtajan system. These two are the only major systems to use the name, and in both these systems it refers to the group more widely known as the monocotyledons. Earlier systems referred to this group by the name Monocotyledones, with Monocotyledoneae an earlier spelling (these names may be used in any rank). Systems such as the Dahlgren and Thorne systems (more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alismatidae
{{Short description, Subclass of flowering plants Alismatidae is a botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used (there are many such systems); the only requirement being that it includes the family Alismataceae. It is a relatively new name: earlier systems, such as the Engler and Wettstein systems, used the name Helobiae for a comparable unit. Alismatidae in the Takhtajan system The Takhtajan system treats this as one of six subclasses within the class Liliopsida (= monocotyledons). It consists of: * subclass Alismatidae *: superorder Alismatanae *:: order Butomales *:: order Hydrocharitales *:: order Najadales *:: order Alismatales *:: order Aponogetonales *:: order Juncaginales *:: order Potamogetonales *:: order Posidoniales *:: order Cymodoceales *:: order Zosterales Alismatidae in the Cronquist system The Cronquist system treats this as one of four subclasses within the class Liliopsid ...
