Tetraena Clavata
''Tetraena'' is a possible genus of flowering plants in the family Zygophyllaceae, subfamily Zygophylloideae. , Plants of the World Online and the World Flora Online accepted it as a synonym of ''Zygophyllum''. Description Species formerly placed in ''Tetraena'' are shrubby or herbaceous, the tallest being around . The leaves are opposite, or sometimes borne on short shoots and then appearing to be alternate. They may or may not have stalks ( petioles). The flower usually has five petals and five sepals, rarely four, and ten stamens. The flower is usually tube-like in appearance with white to pale orange petals. The ovary has three to five chambers (locules). The ripe fruit is variable in shape, splitting into parts before releasing the seeds. Taxonomy The genus ''Tetraena'' was erected by Karl Maximovich in 1889 for the species ''Tetraena mongolica'' (syn. ''Zygophyllum mongolicum''). Until 2003, this was the only species recognized in the genus. Molecular phylogenetic studies su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Karl Maximovich
Carl Johann Maximovich, also Karl Ivanovich Maximovich (Russian language, Russian: Карл Иванович Максимович; 23 November 1827 – 16 February 1891) was a Russian botanist. Maximovich spent most of his life studying the flora of the countries he had visited in the Far East, and naming many new species. He worked at the Saint Petersburg Botanical Gardens from 1852 as curator of the herbarium collection, becoming Director in 1869. History Born a Baltic-German, his name at birth was Karl Ivanovich Maksimovich, but he changed it to the German (language), German version of his name for his scientific work.Japan’s botanical sunrise plant exploration around the Meiji Restoration Peter Barnes (originally published in Curtis's Botanical Magazine 18(1): ...

Zygophyllum Cornutum
''Zygophyllum'' is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek words ζυγόν (''zygon''), meaning "double", and φυλλον (''phyllon''), meaning "leaf". It refers to the leaves, each of which have two leaflets. The genus is distributed in arid and semi-arid regions of Africa, the Mediterranean Basin, central Asia, Australia, and North and South America. Molecular phylogenetic analysis suggested that as previously circumscribed, ''Zygophyllum'' was not monophyletic, and the genus was split among a number of other genera, including '' Augea'', ''Fagonia'', '' Roepera'' and '' Tetraena''. , Plants of the World Online accepted only ''Roepera'' of these genera, regarding ''Augea'', ''Fagonia'' and ''Tetraena'' as synonyms of ''Zygophyllum''. Species , Plants of the World Online accepted 117 species (including those other sources place in ''Augea'', ''Fagonia'' and ''Tetraena''): *'' Zygophyllum acerosum'' (Boiss. ...

Zygophyllum Album
''Zygophyllum album'' (synonym ''Tetraena alba'') is a species of plant in the family Zygophyllaceae which is found in arid regions of Africa and the Arabian Peninsula. It is a salt tolerant plant and dominates many of the plant communities in which it grows. Description ''Zygophyllum album'' is a low, much-branched shrub. The leaves have paired obovoid, fleshy leaflets which are whitish with mealy pubescence. The small flowers are solitary and grow in the axils of the leaves; they have white, clawed petals. The fruit is a five-lobed, pear-shaped capsule containing elliptical seeds with wart-like projections. Distribution This species is found in Spain, Crete, Northern and Northeast Africa, Mauritania, Western Asia (including southern Cyprus, the Eastern Aegean Islands and the Sinai Peninsula) and the Arabian Peninsula. Ecology ''Zygophyllum album'' is a salt-tolerant plant; it does not have glands to secrete the excess salt it takes up, instead it concentrates the salt in its ...

Mats Thulin
A mat is a hard or soft floor covering that generally is placed on a floor or other flat surface. Mats serve a range of purposes including: * serving to clean items passed over it, such as a doormat, which removes dirt from the soles of shoes * protecting that which is above the mat, such as a wrestling or gymnastics mat, or an anti-vibration mat * protecting that which is beneath the mat, such as a place mat or the matting used in archival framing and preservation of documents and paintings * providing a regular or flat surface, such as a cushioned computer mousepad Types In domestic settings * In homes or rooms where people sit predominantly on the floor (common in Japan, Korea, India, and formerly China), mats may cover entire rooms, or be used in certain areas for sitting or sleeping. The traditional Japanese style of mat is known as the tatami. Shoes are typically removed before entering these areas to keep out dirt and debris. * A doormat or door-mat is a flat, u ...
