Orcuttia Californica
''Orcuttia californica'' is a rare species of Poaceae, grass known by the common name California Orcutt grass. Distribution It is native to southern California and northern Baja California, where it grows in scattered locations in vernal pool habitat. In 1993 it was known from fewer than 20 occurrences, including those at the Santa Rosa Plateau, a creek drainage near Hemet, California, Hemet, Otay Mesa, San Diego, California, Otay Mesa in San Diego County, California, San Diego County, and one spot in Woodland Hills, Los Angeles, California, Woodland Hills. ''Orcuttia californica'' is a federally listed endangered species, and its existence is still threatened by the disappearance of vernal pools in the region, a naturally rare habitat type that has been reduced further by urban development.USFWSDetermination of endangered status for three vernal pool plants and the Riverside fairy shrimp ''Federal Register'' August 3, 1993.

George Vasey (botanist)
George Vasey (February 28, 1822 – March 3, 1893) was an English-born American botanist who collected a lot in Illinois before integrating the United States Department of Agriculture (USDA), where he became Chief Botanist and curator of the greatly expanded National Herbarium. Biography George Vasey was born in 1822 near Scarborough, England, the fourth of ten children. His family emigrated to the United States the next year, and they established in Oriskany, New York. He left school at 12 to take a job as a store clerk. He took interest in botany after borrowing and, since he could not afford the volume, manually copying a book on the subject. This interest was later encouraged after a chance encounter with Peter D. Knieskern, another naturalist who allowed Vasey to begin writing to various other botanists. Until 1870 he would maintain an extensive correspondence and collect a great many specimens both in Oneida County and later McHenry County, but did not publish material ...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a Plant stem, stem that is composed of a main branch or a complicated arrangement of branches. Morphology (biology), Morphologically, it is the modified part of the shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), 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 (botany), 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 (botany) , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History Of The Peninsular Ranges
Nature, in the broadest sense, is the physics, physical world or universe. "Nature" can refer to the phenomenon, phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word � ...

Flora Of Baja California
Flora is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bunchgrasses Of North America
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any ...

Orcuttia
''Orcuttia'' is a genus of grass in the family Poaceae. Plants grow up to tall, usually with many stems emerging from the base of the plant, and forming a tuft. The spikelets (groups of flowers) are several-flowered, with reduced upper florets. The lemma tips have between two and five teeth. Described in 1886, the genus contains five species native to California and Baja California. All plants are associated with vernal pools. Plants sprout when the pools are full but grow and flower after the pool bed has dried. These annual grasses, known generally as Orcutt grass, are all rare and federally protected in the United States. Taxonomy ''Orcuttia'' was circumscribed by George Vasey in 1886, based on a collection of ''O. californica'' made by Californian botanist Charles Russell Orcutt, for whom the genus is named. The type locality was near San Quintin Bay in Baja California. ''O. californica'' was not collected again until 1922. ''Orcuttia greenei'' was described ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...
