Haptanthaceae
''Haptanthus'' is a monotypic genus containing the sole species ''Haptanthus hazlettii'', a shrub or small tree known only from the locality of Matarras in the Arizona Municipality in Honduras. Its flowers are unique among the flowering plants. A single "female" (carpellate) flower has two branches on either side which carry "male" (staminate) flowers. The flowers are very simple, lacking obvious sepals or petals. The family placement of the genus has been uncertain, but based on molecular phylogenetic research, it is included in the family Buxaceae . Very few individuals have ever been found and its habitat is threatened by logging. Description ''Haptanthus hazlettii'' is a shrub or tree. It has opposite leaves spaced at 5.5–6.0 cm apart, usually arranged in two ranks (distichous). The leaves are simple with untoothed (entire) margins. There are no stipules. The leaf stalk ( petiole) is short, 7–8 mm long, the leaf blade (lamina) 10–13.5 cm long by 4.1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families followi ...

APG IV System
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. In 2009, a linear arrangement of the system was published separately; the APG IV paper includes such an arrangement, cross-referenced to the 2009 one. Compared to the APG III system, the APG IV system recognizes five new orders (Boraginales, Dilleniales, Icacinales, Metteniusales and Vahliales), along with some new families, making a total of 64 angiosperm orders and 416 families. In general, the authors describe their philosophy as "conservative", based on making changes from APG III only where "a well-supported need" has been demonstrated. This has sometimes resulted in placements that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buxaceae
The Buxaceae are a small family of six genera and about 123 known species of flowering plants. They are shrubs and small trees, with a cosmopolitan distribution. A seventh genus, sometimes accepted in the past (''Notobuxus''), has been shown by genetic studies to be included within ''Buxus'' (Balthazar ''et al.'', 2000). The family is recognised by most taxonomists, and it is commonly known as the box family. However, its placement and circumscription has varied; some taxonomists treated '' Styloceras'' in its own family Stylocerataceae, ''Didymeles'' in its own family Didymelaceae, ''Haptanthus'' in Haptanthaceae (now all included in Buxaceae)), and formerly '' Simmondsia'' was included, which is not related and now usually placed in its own family Simmondsiaceae. The APG II system of 2003 recognises the family, but in a new circumscription in that it includes the genus ''Didymeles'' (two species of evergreen trees from Madagascar). However, APG II does allow the option of segr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monoecy
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma interferenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tela
Tela is a town, with a population of 38,030 (2020 calculation), and a municipality in Honduras on the northern Caribbean coast. It is located in the department of Atlantida. History Colonial era Tela was founded by the Spanish conquistador Cristóbal de Olid on near an indigenous town named Tehuacán, ruled by a cacique named Cucumba which had a very good source of clean water, food and medicinal plants. Olid named his town Triunfo de la Cruz (Triumph of the Cross) as it was founded on this Catholic holy day. The name Triunfo de la Cruz continues to be used to day to refer to a small promontory in the bay. There are historians who say that the origin of the name is a contraction of ''Tetela'', which in the Nahuat language means "land of hills and craggy mountains." Tela, like other towns on the northern Honduras (Atlantic) coast was part of the Western Caribbean Zone and although there was a light Spanish presence was connected powerfully to the world of that zone.

Alexey B
Alexey, Alexei, Alexie, Aleksei, or Aleksey (russian: Алексе́й ; bg, Алексей ) is a Russian and Bulgarian male first name deriving from the Greek ''Aléxios'' (), meaning "Defender", and thus of the same origin as the Latin Alexius. Alexey may also be romanized as ''Aleksei'', ''Aleksey'', ''Alexej'', ''Aleksej'', etc. It has been commonly westernized as Alexis. Similar Ukrainian and Belarusian names are romanized as Oleksii (Олексій) and Aliaksiej (Аляксей), respectively. The Russian Orthodox Church uses the Old Church Slavonic version, Alexiy (Алексiй, or Алексий in modern spelling), for its Saints and hierarchs (most notably, this is the form used for Patriarchs Alexius I and Alexius II). The common hypocoristic is Alyosha () or simply Lyosha (). These may be further transformed into Alyoshka, Alyoshenka, Lyoshka, Lyoha, Lyoshenka (, respectively), sometimes rendered as Alesha/Aleshenka in English. The form Alyosha may be ...

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Andrew N
Andrew is the English form of a given name common in many countries. In the 1990s, it was among the top ten most popular names given to boys in English-speaking countries. "Andrew" is frequently shortened to "Andy" or "Drew". The word is derived from the el, Ἀνδρέας, ''Andreas'', itself related to grc, ἀνήρ/ἀνδρός ''aner/andros'', "man" (as opposed to "woman"), thus meaning "manly" and, as consequence, "brave", "strong", "courageous", and "warrior". In the King James Bible, the Greek "Ἀνδρέας" is translated as Andrew. Popularity Australia In 2000, the name Andrew was the second most popular name in Australia. In 1999, it was the 19th most common name, while in 1940, it was the 31st most common name. Andrew was the first most popular name given to boys in the Northern Territory in 2003 to 2015 and continuing. In Victoria, Andrew was the first most popular name for a boy in the 1970s.
