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. Genetic and morphological characteristics of wheat influence its classification; many common and botanical names of wheat are in current use.
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 umbellulata, the umbel goatgrass, is an annual grass that is closesly related to wheat. It is native to southeastern Europe, Iran, Iraq, Lebanon, Syria, the Transcaucasus, and Turkey.
Aegilops triuncialis, or barbed goatgrass, is a grass species of the family Poaceae. It is a winter annual 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.
Nassella pulchra, basionym Stipa pulchra, is a species of grass known by the common names purple needlegrass and purple tussockgrass. It is native to the U.S. state of California, where it occurs throughout the coastal hills, valleys, and mountain ranges, as well as the Sacramento Valley and parts of the Sierra Nevada foothills, and Baja California.
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.
Thorne's meadow nematode is a plant pathogenic nematode.
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.
Hirschfeldia incana is a species of flowering plant in the mustard family known by many common names, including shortpod mustard, buchanweed, hoary mustard and Mediterranean mustard. It is the only species in the monotypic genus Hirschfeldia, which is closely related to Brassica. The species is native to the Mediterranean Basin but it can be found in many parts of the world as an introduced species and often a very abundant noxious weed. This mustard is very similar in appearance to black mustard, but is generally shorter. It forms a wide basal rosette of lobed leaves which lie flat on the ground, and it keeps its leaves while flowering. Its stem and foliage have soft white hairs. Unlike black mustard, H. incana is a perennial plant.
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.
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. In Chishona, its name is bhurakwacha.
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.
