Hordeum Depressum
''Hordeum depressum'' is a species of Hordeum, barley known by the common names low barley and dwarf barley. It is native to the western United States from Idaho to California, where it can be found in moist habitats such as vernal pools. This is a small annual grass forming petite patches of thin, hairy leaves and erect stems to half a meter in maximum height. The green or reddish green inflorescence is 2 to 6 centimeters long and about half a centimeter wide. Like other barleys the spikelets come in triplets. There is a large fertile central spikelet about a centimeter long and two smaller, often sterile spikelets on Pedicel (botany), pedicels, each 3 to 5 millimeters long.

Jared Gage Smith
Jared is a given name of Biblical derivation. Origin In the Book of Genesis, the biblical patriarch Jared (יֶרֶד) was the sixth in the ten pre-flood generations between Adam and Noah; he was the son of Mahalaleel and the father of Enoch, and lived 962 years (Genesis 5:18). The biblical text in the Book of Jubilees implicitly etymologizes the name as derived from the root YRD "descend", because in his days "the angels of the Lord ''descended'' to earth". Alternative suggestions for the name's etymology include words for "rose", "servant" and "one who rules".Hess, Richard S., ''Studies in the personal names of Genesis 1-11'' (1993), p. 69. Yared (505–571), a namesake, was an Ethiopian monk who introduced the concept of sacred music to Ethiopian Orthodox services. He is regarded as a saint of the Ethiopian Orthodox Church with a feast day of 11 Genbot (May 19). In the English language, Jared is both a common Jewish and Christian-Protestant first name.

Per Axel Rydberg
Per Axel Rydberg (July 6, 1860 – July 25, 1931) was a Swedish-born, American botanist who was the first curator of the New York Botanical Garden Herbarium. Biography Per Axel Rydberg was born in Odh, Västergötland, Sweden and emigrated to the United States in 1882. From 1884 to 1890, he taught mathematics at Luther Academy in Wahoo, Nebraska, while he studied at the University of Nebraska. He graduated from the University of Nebraska–Lincoln (B.S. in 1891) and (M.A. in 1895). He earned his graduate degree from Columbia University (Ph.D. in 1898). After he graduated, Rydberg received a commission from the United States Department of Agriculture to undertake a botanical exploration of western Nebraska. He received another one in 1892 to explore the Black Hills of South Dakota, and in 1893 he was in the Sand Hills, again in western Nebraska. During this time he continued to teach at the Luther Academy. In 1900 Rydberg conducted field work in southeast Colorado. In 1901 ...

Hordeum
''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. One species, ''Hordeum vulgare'' (barley), has become of major commercial importance as a cereal grain, used as fodder crop and for malting in the production of beer and whiskey. Some species are nuisance weeds introduced worldwide by human activities, others have become endangered due to habitat loss. ''Hordeum'' species are used as food plants by the larvae of some Lepidoptera species, including the flame, rustic shoulder-knot and setaceous Hebrew character. The name '' Hordeum'' comes from the Latin word for "to bristle" (''horreō'', ''horrēre''), and is akin to the word " horror". Species Species include: * '' Hordeum aegiceras'' – Mongolia, China including Tibet * ''Hordeum arizonicum'' US (CA AZ NV NM), Mexico (Baja California, Sonora, Durango) * '' Hordeum bogdanii'' – from Turkey and European Ru ...

Idaho
Idaho ( ) is a state in the Pacific Northwest region of the Western United States. To the north, it shares a small portion of the Canada–United States border with the province of British Columbia. It borders the states of Montana and Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. The state's capital and largest city is Boise. With an area of , Idaho is the 14th largest state by land area, but with a population of approximately 1.8 million, it ranks as the 13th least populous and the 7th least densely populated of the 50 U.S. states. For thousands of years, and prior to European colonization, Idaho has been inhabited by native peoples. In the early 19th century, Idaho was considered part of the Oregon Country, an area of dispute between the U.S. and the British Empire. It officially became U.S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead ...

Vernal Pool
Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by fish. Certain tropical fish lineages (such as killifishes) have however adapted to this habitat specifically. Vernal pools are a type of wetland. They can be surrounded by many communities/species including deciduous forest, grassland, lodgepole pine forest, blue oak woodland, sagebrush steppe, succulent coastal scrub and prairie. These pools are characteristic of Mediterranean climates, but occur in many other ecosystems. Generation and annual development During most years, a vernal pool basin will experience inundation from rain/precipitation, followed by desiccation from evapotranspiration. These conditions are commonly associated with M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".
