Phlox Dolichantha
''Phlox dolichantha'' is a species of phlox known by the common name Big Bear Valley phlox. It is endemic to San Bernardino County, California, where it is limited to the area around Big Bear Lake in the San Bernardino Mountains. It grows in forests and the unique local pebble plain habitat. It occurs at elevations over 2000 meters. It is an erect, branching perennial herb growing up to 30 centimeters tall. The linear or narrowly lance-shaped leaves are 2 to 5 centimeters long and are oppositely arranged on the slender stems. The inflorescence is made up of one or more showy flowers at the tip of the stem. Each flower has a very slender tubular throat up to 5 centimeters long which can be white, pink, or lavender. The flowers are pollinated by a variety of insects including the hawkmoth ''Hyles lineata'' and flies of the genera ''Anthomyia ''Anthomyia'' is a genus of flies in the family Anthomyiidae.

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His '' Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ...

Pollination
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the ...

Big Bear Valley
Big Bear Valley is a valley in San Bernardino County, California, United States. The valley, in the San Bernardino Mountains, includes Big Bear Lake, Big Bear City, Fawnskin, Holcomb Valley, Sugarloaf, Erwin Lake, Baldwin Lake, Bluff Lake and Lake Williams. History The Spanish colonizers arrived to the valley in the eighteenth century and encountered people who they referred to as "Serranos Serranos is a municipality in the state of Minas Gerais in the Southeast region of Brazil. See also *List of municipalities in Minas Gerais This is a list of the municipalities in the state of Minas Gerais (MG), located in the Southeast Regio ..." in the valley. The Serranos had established a few permanent settlements in the mountains, and also lived in the area during the summer months of the year. They may have moved into the area some 3,000 years prior.

Endemic Flora Of California
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phlox
''Phlox'' (; Greek φλόξ "flame"; plural "phlox" or "phloxes", Greek φλόγες ''phlóges'') is a genus of 67 species of perennial and annual plants in the family Polemoniaceae. They are found mostly in North America (one in Siberia) in diverse habitats from alpine tundra to open woodland and prairie. Some flower in spring, others in summer and fall. Flowers may be pale blue, violet, pink, bright red, or white. Many are fragrant. Description The name is derived from the Greek word ''phlox'' meaning flame in reference to the intense flower colors of some varieties. Fertilized flowers typically produce one relatively large seed. The fruit is a longitudinally dehiscent capsule with three or more valves that sometimes separate explosively. Some species such as '' P. paniculata'' (garden phlox) grow upright, while others such as '' P. subulata'' (moss phlox, moss pink, mountain phlox) grow short and matlike. Paniculata or tall phlox, is a native American wildflower that i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hyles Lineata
''Hyles lineata'', also known as the white-lined sphinx, is a moth of the family Sphingidae. They are sometimes known as the hummingbird moth because of their bird-like size (2-3 inch wingspan) and flight patterns. As caterpillars, they have a wide range of color phenotypes but show consistent adult coloration. With a wide geographic range throughout Central and North America, ''H. lineata'' is known to feed on many different host plants as caterpillars and pollinate a variety of flowers as adults. Larvae are powerful eaters and are known to form massive groupings capable of damaging crops and gardens. As adults, they use both visual and olfactory perception to locate plants from which they collect nectar. Description Caterpillar Larvae show wide variation in color. The larvae are black with orange spots arranged in lines down the whole body. Their head's prothoracic shield, and the anal plate, are one color, either green or orange with small black dots.David L. Wagner (200 ... [...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 ...

Herbaceous Plant
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the par ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions.
