Camissonia Campestris
''Camissonia campestris'' (field primrose,Mojave Desert Wildflowers, Pam MacKay, 2nd ed., 2013, Mojave sun cup, or Mojave suncup), is a flowering plant in the family Onagraceae, native to the Mojave Desert of the United States. It grows mostly on open, sandy flats, occurring from sea level to 2,000 m in the western and central part of the desert. It is an annual plant growing to 5–25 cm tall (rarely to 50 cm tall). The leaves are linear, 0.5–3 cm long, with a finely serrated margin.

Gorman, California
Gorman is an unincorporated community in northwestern Los Angeles County. It is located in Peace Valley south of the Tejon Pass, which links Southern California with the San Joaquin Valley and Northern California. Due to this location, the area has served as a historic travel stop dating back to the indigenous peoples of California. Tens of thousands of motorists travel through Gorman daily on the Golden State Freeway (Interstate 5) since the highway's completion in the mid-20th Century. Geography Gorman is in size. It lies where three Transverse System mountain ranges meet, namely the Sierra Pelona Mountains, the Tehachapi Mountains, and the San Emigdio Mountains. One of the Mountain Communities of the Tejon Pass, it is southeast of Frazier Park and south of Lebec. Interstate 5 runs through Gorman, and State Route 138 connects to the freeway a few miles south. California poppies, lupines, and other wildflowers dramatically cover the hills in the springtime when there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Lee Greene
Edward Lee Greene (August 20, 1843–November 10, 1915) was an American botanist known for his numerous publications including the two-part ''Landmarks of Botanical History'' and the describing of over 4,400 species of plants in the American West. Early life Edward Lee Greene was born on August 20, 1843 in Hopkinton, Rhode Island. In 1859 Greene moved to Wisconsin and began studying at Albion Academy, a very reputable institution with a religious emphasis. There Greene met Thure Kumlien, a Swedish Naturalist with an interest in botany. Greene accompanied Kumlein on field trips, further developing Greene's interest in botany. In August 1862, Greene joined his father and brothers in joining the 13th Wisconsin Volunteer Infantry Regiment of the Union Army. Though he never rose above the rank of private in his three years of service, Greene was able to advance his botanical studies, collecting specimens as he marched through Tennessee, Kentucky and Alabama. Following his release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peter Hamilton Raven
Peter Hamilton Raven (born June 13, 1936) is an American botanist and environmentalist, notable as the longtime director, now President Emeritus, of the Missouri Botanical Garden. Early life On June 13, 1936, Raven was born in Shanghai, China to American parents, Walter Francis Raven and Isabelle Marion Breen. His father's uncle Frank Jay Raven was, for a time, one of the wealthiest Americans in China, but was later jailed in a banking scandal. That incident and Japanese aggression in China led the Raven family to return to San Francisco, CA in the late 1930s. After becoming a member of the California Academy of Sciences while still a youth, Raven went on to graduate with a BSc in biology from the University of California, Berkeley in 1957 and a Ph.D. in botany from the University of California, Los Angeles in 1960. Career After teaching at Stanford University, Raven went on to become Director of the Missouri Botanical Garden in 1971. In 2006, his position was renamed Presid ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mojave Desert
The Mojave Desert ( ; mov, Hayikwiir Mat'aar; es, Desierto de Mojave) is a desert in the rain shadow of the Sierra Nevada mountains in the Southwestern United States. It is named for the indigenous Mojave people. It is located primarily in southeastern California and southwestern Nevada, with small portions extending into Arizona and Utah. The Mojave Desert, together with the Sonoran, Chihuahuan, and Great Basin deserts, forms a larger North American Desert. Of these, the Mojave is the smallest and driest. The Mojave Desert displays typical basin and range topography, generally having a pattern of a series of parallel mountain ranges and valleys. It is also the site of Death Valley, which is the lowest elevation in North America. The Mojave Desert is often colloquially called the "high desert", as most of it lies between . It supports a diversity of flora and fauna. The desert supports a number of human activities, including recreation, ranching, and military training. ...

Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camissonia
''Camissonia'', sometimes commonly known as sun cup or sundrop, is a genus of annual and perennial plants in the evening primrose family Onagraceae. A total of 12 species are known, nearly all from western North America, especially in the California Floristic Province, but also one from South America. Previous circumscriptions of the genus had recognized up to 62 species before it was split among other closely related genera.Wagner WL, PC Hoch, and PH Raven. 2007Revised classification of the Onagraceae ''Systematic Botany Monographs'', 83: 1-240. The flowers generally open at dawn and are yellow. They are usually cup-shaped, thus the common name. Formerly included in ''Oenothera'', the species of ''Camissonia'' are distinguished by having a club- or head-shaped carpel, stigma, instead of the 4-part-divided stigma of ''Oenothera'' or ''Clarkia''. ''Camissonia'' species are used as food plants by the larvae of some Lepidoptera species including ''Schinia, Schinia cupes'' and ''Sch ...

North American Desert Flora
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
