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.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
Croton is an extensive flowering plant genus in the spurge family, Euphorbiaceae. The plants of this genus were described and introduced to Europeans by Georg Eberhard Rumphius. The common names for this genus are rushfoil and croton, but the latter also refers to Codiaeum variegatum. The generic name comes from the Greek κρότος, which means "tick" and refers to the shape of the seeds of certain species.
Hordeum jubatum, with common names foxtail barley, bobtail barley, squirreltail barley, and intermediate barley, is a perennial plant species in the grass family Poaceae. It occurs wild mainly in northern North America and adjacent northeastern Siberia. However, as it escaped often from gardens it can be found worldwide in areas with temperate to warm climates, and is considered a weed in many countries. The species is a polyploid and originated via hybridization of an East Asian Hordeum species with a close but extinct relative of Californian H. brachyantherum. It is grown as an ornamental plant for its attractive inflorescences and when done flowering for its infructescence.
Hordeum murinum, commonly known as wall barley or false barley, is a species of grass.
Ilex ovalis is a species of flowing plant in the holly family Aquifoliaceae. It is native to Ecuador and Peru.
Hordeum pusillum, the little barley, is an annual grass native to the United States. It arrived via multiple long-distance dispersals of a southern South American species of Hordeum about one million years ago. Its closest relatives are therefore not the other North American taxa like meadow barley or foxtail barley, but rather Hordeum species of the pampas of central Argentina and Uruguay. It is less closely related to the Old World domesticated barley, from which it diverged about 12 million years ago. It is diploid.
Hordeum brachyantherum, known by the common name meadow barley, is a species of barley. It is native to western North America from Alaska to northern Mexico, coastal areas of easternmost Russia (Kamchatka), and a small area of coastal Newfoundland.
Barley, a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains, particularly in Eurasia as early as 10,000 years ago. Barley has been used as animal fodder, as a source of fermentable material for beer and certain distilled beverages, and as a component of various health foods. It is used in soups and stews, and in barley bread of various cultures. Barley grains are commonly made into malt in a traditional and ancient method of preparation.
The angulate tortoise is a species of tortoise found in dry areas and coastal scrub vegetation in South Africa. This tortoise in the only known member of the genus Chersina.
Hordeum intercedens is an diploid, annual species of wild barley known by the common names bobtail barley and vernal barley. It is native to southern California and northern Baja California, where it is an increasingly rare member of the flora in saline and alkaline soils near seasonal waterflows and vernal pool habitats. Today most occurrences are located on the Channel Islands of California; many of the occurrences known from the mainland have been extirpated in the process of land development. This is an annual grass growing erect to bent in small tufts with stems up to 40 centimeters long. The inflorescence is a green spike up to 6.5 centimeters long made up of awned spikelets between 1 and 2 centimeters long.
Leucadendron album is a species of flowering plant in the family Proteaceae that grows in South Africa.
Croton lechleri is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to northwestern South America. It is commonly known as sangre de grado, sangre de drago or sangre de grada, both of which translate to "dragon's blood". They refer to this tree's thick red latex.
Crofelemer is a botanical drug for the treatment of diarrhea associated with anti-HIV drugs such as nucleoside analog reverse transcriptase inhibitors and protease inhibitors. Other possible uses include diarrhea in children, acute infectious diarrhea, and diarrhea in patients with irritable bowel syndrome. It is a purified oligomeric proanthocyanidin from "dragon's blood", the sap of the South American tree Croton lechleri.
Hordeum pubiflorum, also known as Antarctic barley, is a perennial that is native to western and southern South America.
Leucadendron laureolum is a species of plant in the family Proteaceae with common names golden conebush and laurel leaf conebush. It is endemic to South Africa and also cultivated. It is a large bush that turns bright yellow in the winter flowering season.
Desmophlebium is a genus of ferns. In the Pteridophyte Phylogeny Group classification of 2016, it is the only genus in the family Desmophlebiaceae. Other sources place it in a more widely defined Aspleniaceae.
Hordeum distichon, the common barley or two-rowed barley, is a cultigen of barley, family Poaceae. It is native to Iraq, and is widely grown throughout temperate regions of the world. Some authorities consider it a subspecies of six-rowed barley, Hordeum vulgare. It is the principal raw material for malting and brewing beer in Europe, as it is lower in protein than the six-rowed barley usually used in North America.
Hordeum bulbosum, bulbous barley, is a species of barley native to southern Europe, northern Africa, the Middle East and as far east as Afghanistan, with a few naturalized populations in North America, South America and Australia. Since 1970 it has been used in the Hordeum bulbosum Method to produce doubled haploid (DH) wheat and barley plants by crossing it with T. aestivum or H. vulgare, followed by the elimination of the H. bulbosum chromosomes from the offspring. These DH plants are important in breeding new varieties of wheat and barley, and in scientific studies. H. bulbosum is also being looked at as a source of genes for disease resistance and other traits for barley crop improvement.
Hordeum secalinum, false rye barley and meadow barley, is a species of wild barley native to Europe, including the Madeiras, Crimea and the north Caucasus, northwest Africa, and the Levant. It has been introduced to Australia and New Zealand. An allotetraploid, it arose from ancestors with the Xa and IHordeum genomes.
