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.
During 10,000 years of cultivation, numerous forms of wheat, many of them hybrids, have developed under a combination of artificial and natural selection. This diversity has led to much confusion in the naming of wheats. This article explains how genetic and morphological characteristics of wheat influence its classification, and gives the most common botanical names of wheat in current use. Information on the cultivation and uses of wheat is at the main wheat page.
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.
Aegilops tauschii, the Tausch's goatgrass or rough-spike hard grass, is an annual grass species. It is native to Crimea, the Caucasus region, western and Central Asia, Afghanistan, Pakistan, the western Himalaya, and parts of China, and has been introduced to other locales, including California.
Aegilops kotschyi is a member of the grass family, Poaceae, native to the Levant.
Aegilops triuncialis, or barbed goatgrass, is a winter annual grass species of the family Poaceae. It is native to many areas in Eastern and Mediterranean Europe and Western Asia. It is considered an introduced, invasive species in North America, mainly in the Western coast of the United States. In its native lands, the grass thrives in mainly rocky, serpentine soil, but also does well in grasslands and ruderal/disturbed ground as well as oak woodlands.
Agrostis nebulosa is a species of flowering plant in the family Poaceae. It is referred to by the common name cloud grass, and is an ornamental plant native to Morocco, Portugal and Spain. This plant is often cultivated for its light delicate heads that are used dried in floristry.
Vulpia is a widespread genus of plants in the grass family, native to many countries around the world and naturalized in many of the nations to which it is not native. It is most common in temperate regions.
Danthonia californica is a species of grass known by the common name California oatgrass. This plant is native to two separate regions of the Americas, western North America from California to Saskatchewan, and Chile.
Eleocharis geniculata is a species of spikesedge known by several common names, including bent spikerush and Canada spikesedge. This is a widespread plant of wet areas in the Americas, Asia, Africa, Australia, Madagascar, and some Pacific Islands. It is an annual spikesedge growing to a maximum height of about 40 centimeters. It has a few straw-colored leaves and many thin erect stems. The stems hold inflorescences of rounded spikelets each containing at least 10 tiny flowers. The flowers are covered with dark greenish-brown bracts. The fruit is a shiny purple-brown achene not more than a millimeter long.
Festuca idahoensis is a species of grass known by the common names Idaho fescue and blue bunchgrass. It is native to western North America, where it is widespread and common. It can be found in many ecosystems, from shady forests to open plains grasslands.
Briza minor is a species of grass known by the common names lesser quaking-grass or little quakinggrass. It is native to the Mediterranean Basin, and it is known elsewhere, including much of North America, as an introduced species. It is an annual grass producing narrow clumps of erect stems up to 50 centimeters tall. The inflorescence bears several small cone-shaped spikelets, each hanging on a pedicel.
Parapholis incurva is a species of grass native to Europe, Asia and northern Africa, and widely naturalised elsewhere. Common names include coast barbgrass, curved sea hard grass, curved hard-grass, sicklegrass, curved sicklegrass and curved parapholis.
Polypogon monspeliensis, commonly known as annual beard-grass or annual rabbitsfoot grass, is a species of grass. It is native to southern Europe, but it can be found today throughout the world as an introduced species and sometimes a noxious weed. It is an annual grass growing to heights between 5 centimeters and one meter. The soft, fluffy inflorescence is a dense, greenish, plumelike panicle, sometimes divided into lobes. The spikelets have long, thin, whitish awns, which give the inflorescence its texture.
Paspalum dilatatum is a species of grass known by the common name dallisgrass, Dallas grass, or sticky heads. It is native to Brazil and Argentina, but it is known throughout the world as an introduced species and at times a common weed. Its rapid growth and spreading rhizomes make it an invasive pest in some areas. It is present in the southern half of North America, southern Europe, much of Africa, Australia, New Zealand, and many tropical and subtropical areas.
Melinis repens is a species of grass known by the common names rose Natal grass, Natal red top, or simply Natal grass. It is native to southern Africa and an introduced species, often considered a noxious weed, on other continents such as North America and Australia. It is an annual or perennial grass, growing up to a meter tall. Its growth rate is dependent on temperature. The inflorescence is an open array of branches bearing spikelets densely coated in silky white or pink hairs.
Melanargia russiae, or Esper's marbled white, is a butterfly in the family Nymphalidae. It is found in Spain, Portugal, south-eastern France, Italy, the Balkans, southern Russia, the Caucasus and western Siberia.
Aegilops neglecta, common name three-awn goat grass, is a species in the family Poaceae.
Setaria verticillata is a species of grass known by the common names hooked bristlegrass, rough bristle-grass and bristly foxtail. It is native to Europe, but it is known on most continents as an introduced species and often a noxious weed. It is a hardy bunchgrass which grows in many types of urban, cultivated, and disturbed habitat. It is a weed of many types of agricultural crops, growing in vineyards and fields. Herbicide-resistant strains have been noted.
Traiguera is a town and municipality in the Baix Maestrat comarca, province of Castelló, Valencian Community, Spain. It is part of the Taula del Sénia free association of municipalities.
