Houttuynia
''Houttuynia'' is a genus of two species in the Saururaceae native to Southeast Asia. One species, '' H. cordata'', is widely cultivated as a culinary herb. The genus was originally described in 1783 by Carl Peter Thunberg when he formally described ''H. cordata'' as the only species. It remained a monotypic genus until 2001 when Zheng Yin Zhu and Shi Liang Zhang discovered and described a second species native to China, '' H. emeiensis'' but the validity still unestablished.Wu Wei, Zheng Youliang, Chen Li, Wei Yuming, Yan Zehong, and Yang Ruiwu. 2005PCR-RFLP analysis of cpDNA and mtDNA in the genus ''Houttuynia'' in some areas of China.''Hereditas'' 142: 24-32.

Houttuynia Cordata
''Houttuynia cordata'', also known as fish mint, fish leaf, rainbow plant, chameleon plant, heart leaf, fish wort, or Chinese lizard tail, is one of two species in the genus ''Houttuynia'' (the other being ''H. emeiensis''). It is a flowering plant native to Southeast Asia. It grows in moist, shady locations. It was named after Martinus Houttuyn. Growth ''Houttuynia cordata'' is a herbaceous perennial plant that can grow to , spreading up to . The proximal part of the stem is trailing and produces adventitious roots, while the distal part of the stem grows vertically. The leaves are alternate, broadly heart-shaped, long and broad. Its flowers are greenish-yellow and borne on a terminal spike long with four to six large white basal bracts. It normally blooms in the summer. It is considered an invasive plant because of its ability to regrow rhizomes from any segment of its foliage.

Saururaceae
Saururaceae is a plant family comprising four genera and seven species of herbaceous flowering plants native to eastern and southern Asia and North America. The family has been recognised by most taxonomists, and is sometimes known as the "lizard's-tail family". The APG IV system (2016; unchanged from the 2009 APG III system, the 2003 APG II system and the 1998 APG system) assigned it to the order Piperales in the clade magnoliids.

Martinus Houttuyn
Maarten Houttuyn or Houttuijn (1720 – 2 May 1798) Latinised as Martinus Houttuyn, was a Dutch naturalist. Houttuyn was born in Hoorn, studied medicine in Leiden and moved to Amsterdam in 1753. He published many books on natural history, e.g. ''Natuurlyke Historie of uitvoerige Beschryving der Dieren, Planten en Mineraalen, volgens het Samenstel van den Heer Linnaeus'', in 37 volumes (1761-1773), following Carl Linnaeus' division into the animal kingdom, the plant kingdom, and the mineral kingdom. His areas of interest encompassed Pteridophytes, Bryophytes and Spermatophytes. He died in Amsterdam. In botanical nomenclature, the standard author abbreviation ''Houtt.'' is applied to plants described by him. He is commemorated by the genus ''Houttuynia'', a member of the Saururaceae from China and Japan. Martinus Houttuyn was the co-writer of the volumes 2, 3, 4 and 5 of '' Nederlandsche Vogelen''.His name appears on the title pages ovol 2 an of ''Nederlandsche Vogelen''. ...

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Swedish naturalist and an "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Africa and Asia, collecting and describing many plants and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to Paris and Amsterdam. In Amsterdam and Leiden Thunberg met the Dutch botanist ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southeast Asia
Southeast Asia, also spelled South East Asia and South-East Asia, and also known as Southeastern Asia, South-eastern Asia or SEA, is the geographical United Nations geoscheme for Asia#South-eastern Asia, south-eastern region of Asia, consisting of the regions that are situated south of mainland China, east of the Indian subcontinent, and north-west of mainland Australia. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia (continent), Australia and the Indian Ocean. Apart from the British Indian Ocean Territory and two out of atolls of Maldives, 26 atolls of Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere. Mainland Southeast Asia is completely in the Northern Hemisphere. East Timor and the southern portion of Indonesia are the only parts that are south of the Equator. Th ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Piperales Genera
Piperales is an order of flowering plants (4,170 recognized species). It necessarily includes the family Piperaceae but other taxa have been included or disincluded variously over time. Well-known plants which may be included in this order include black pepper, kava, pepper elder, lizard's tail, birthwort, and wild ginger. Classification APG system In the APG IV system, of 2016, this order is placed in the clade magnoliids and is circumscribed as follows: *order Piperales *: family Aristolochiaceae (including Asaraceae, Hydnoraceae and Lactoridaceae) *: family Piperaceae *: family Saururaceae This is an expansion from the APG system, of 1998, which used the same placement (in the magnoliids) but used this circumscription: * order Piperales'' *: family Aristolochiaceae *: family Lactoridaceae *: family Piperaceae *: family Saururaceae Earlier systems The Cronquist system, of 1981, placed the order in the subclass Magnoliidae of class Magnoliopsida dicotyledonsand used ...
