Hystrix (plant)

Last updated

Hystrix was a formerly recognized genus of grass (family Poaceae).

The genus Hystrix was created in 1794 by Conrad Moench for the species described as Elymus hystrix by Carl Linnaeus in 1753. [1] Moench considered that E. hystrix was sufficiently distinct to be placed in a separate genus as Hystrix patula; the genus was to be used for species without glumes or with long setaceous glumes. Subsequently a number of other grass species were placed in this genus. [2]

Genomic studies from the 1960s onwards showed that H. patula does in fact belong in Elymus, as this is now defined. Other species placed in Hystrix have genomes more closely resembling those of Leymus species, and are better placed in that genus. [3] [2] Currently accepted transfers include: [2]

Cyprinidae Family of fishes

The Cyprinidae are the family of freshwater fish, collectively called cyprinids, that includes the carps, the true minnows, and their relatives. Also commonly called the "carp family", or "minnow family", Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general, with about 3,000 species of which only 1,270 remain extant, divided into about 370 genera. They range from about 12 mm to the 3-m Catlocarpio siamensis. The family belongs to the ostariophysian order Cypriniformes, of whose genera and species the cyprinids make up more than two-thirds. The family name is derived from the Ancient Greek kyprînos.

<i>Oryza</i> Genus of plants

Oryza is a genus of plants in the grass family. It includes the major food crop rice. Members of the genus grow as tall, wetland grasses, growing to 1–2 m tall; the genus includes both annual and perennial species.

<i>Hordeum</i> Genus of grasses

Hordeum is a genus of annual and perennial plants in the grass family. They are native throughout the temperate regions of Africa, Eurasia, and the Americas.

Salamandridae Family of amphibians

Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands.

<i>Festuca</i> genus of flowering plants in the grass family Poaceae

Festuca (fescue) is a genus of flowering plants belonging to the grass family Poaceae. They are evergreen or herbaceous perennial tufted grasses with a height range of 10–200 cm (4–79 in) and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (Lolium), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus Festuca into the genus Lolium, or alternatively into the segregate genus Schedonorus.

<i>Aegilops</i> Genus of grasses

Aegilops is a genus of Eurasian and North American plants in the grass family, Poaceae. They are known generally as goatgrasses. Some species are known as invasive weeds in parts of North America.

<i>Jeholornis</i>

Jeholornis is a genus of avialans that lived between approximately 122 and 120 million years ago during the early Cretaceous Period in China. Fossil Jeholornis were first discovered in the Jiufotang Formation in Hebei Province, China and additional specimens have been found in the older Yixian Formation.

Triticeae Tribe of grasses

Triticeae is a botanical tribe within the subfamily Pooideae of grasses that includes genera with many domesticated species. Major crop genera found in this tribe include wheat, barley, and rye; crops in other genera include some for human consumption, and others used for animal feed or rangeland protection. Among the world's cultivated species, this tribe has some of the most complex genetic histories. An example is bread wheat, which contains the genomes of three species with only one being a wheat Triticum species. Seed storage proteins in the Triticeae are implicated in various food allergies and intolerances.

Pareuchiloglanis is a genus of sisorid catfishes native to Asia. These species are rheophilic catfish chiefly found in the headwaters of major rivers in South and East Asia. They originate from the Brahmaputra drainage in India, east and south to the Yangtze drainage in China and the Annamese Cordillera drainages in southern Vietnam. Two species are known from the Mekong River: P. myzostoma and P. gracilicaudata. Four species are known from the drainage of China: P. abbreviatus, P. gracilicaudata, P. myzostoma and P. prolixdorsalis.

<i>Leymus mollis</i>

Leymus mollis is a species of grass known by the common names American dune grass, American dune wild-rye, sea lyme-grass, strand-wheat, and strand grass. Its Japanese name is hamaninniku. It is native to Asia, where it occurs in Japan, China, Korea, and Russia, and northern parts of North America, where it occurs across Canada and the northern United States, as well as Greenland. It can also be found in Iceland.

Oryzoideae Subfamily of plants

Oryzoideae (syn. Ehrhartoideae) is a subfamily of the true grass family Poaceae. It includes around 120 species in 19 genera, notably the major cereal crop rice. Within the grasses, this subfamily is one of three belonging to the species-rich BOP clade, which all use C3 photosynthesis; it is the basal lineage of the clade.

Anchiornithidae

Anchiornithidae is a family of eumaniraptorans which could be the basalmost family of birds in the clade Avialae. Anchiornithids have been classified at varying positions in the maniraptoran tree, with some scientists classifying them as a distinct family, a basal subfamily of Troodontidae, members of Archaeopterygidae, or an assemblage of dinosaurs that are an evolutionary grade within Avialae or Paraves.

Mòjiāng virus(MojV), officially Mojiang henipavirus, is a virus in the family Paramyxoviridae. Based on phylogenetics, Mòjiāng virus is placed in the genus Henipavirus or described as a henipa-like virus. Antibodies raised against Mòjiāng virus glycoproteins are serologically distinct from other henipaviruses.
