Linanthus Maculatus
''Linanthus maculatus'' (formerly ''Gilia maculata'') is a species of flowering plant in the phlox family known by the common names San Bernardino Mountain gilia and Little San Bernardino Mountains gilia. It is endemic to California, where it is known only from a few locales in the Little San Bernardino Mountains and the adjacent Palm Springs area in the northern end of the Coachella Valley. The largest populations, which may contain thousands of individuals, are located within the bounds of Joshua Tree National Park.Sanders, A.CLittle San Bernardino Mountains GiliaBLM Management Report. This is a very small annual herb no more than three centimeters high. It has a taproot which may exceed 6 centimeters in length to collect moisture from the dry desert sand in its native habitat. The tiny, hairy stem branches to form small matted clusters on the sand surface. The hairy leaves are just a few millimeters long and unlobed. The inflorescence is a dense cluster of flowers each only 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polemoniaceae
The Polemoniaceae (Jacob's-ladder or phlox family) are a family of flowering plants consisting of about 25 genera with 270–400 species of annuals and perennials native to the Northern Hemisphere and South America, with the center of diversity in western North America. Only one genus (''Polemonium'') is found in Europe, and two (''Phlox'' and ''Polemonium'') in Asia, where they are confined to cool temperate to arctic regions; both genera also occur more widely in North America, suggesting relatively recent colonization of the Old World from North America. The family can be distinguished from most other eudicot families by the ovary made up of three fused carpels (usually with three chambers, but with one chamber in some species). The members of the family have five sepals, five petals fused, and five stamens that alternate with the lobes of the corolla. For decades, most sources used a classification of the family published by Grant in 1959, but new evidence, including mol ...

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palm Springs, California
Palm Springs (Cahuilla: ''Séc-he'') is a desert resort city in Riverside County, California, United States, within the Colorado Desert's Coachella Valley. The city covers approximately , making it the largest city in Riverside County by land area. With multiple plots in checkerboard pattern, more than 10% of the city is part of the Agua Caliente Band of Cahuilla Indians reservation land and is the administrative capital of the most populated reservation in California. The population of Palm Springs was 44,575 as of the 2020 census, but because Palm Springs is a retirement location and a winter snowbird destination, the city's population triples between November and March. The city is noted for its mid-century modern architecture, design elements, arts and cultural scene, and recreational activities. History Founding Pre-colonial history The first humans to settle in the area were the Cahuilla people, who arrived 2,000 years ago.Baker, Christopher P. (2008). ''E ...

Taproot
A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward. In some plants, such as the carrot, the taproot is a storage organ so well developed that it has been cultivated as a vegetable. The taproot system contrasts with the adventitious or fibrous root system of plants with many branched roots, but many plants that grow a taproot during germination go on to develop branching root structures, although some that rely on the main root for storage may retain the dominant taproot for centuries, for example ''Welwitschia''.Taproot also store nutrition. Plants with taproots are often vegetables. Description Dicots, one of the two divisions of flowering plants (angiosperms), start with a taproot, which is one main root forming from the enlarging radicle of the seed. The tap root can be persistent throughout the life of the plant but is most oft ... [...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 ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Off-road Vehicle
An off-road vehicle, sometimes referred to as an overland or adventure vehicle, is considered to be any type of vehicle which is capable of driving on and off paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension, or even caterpillar tracks. Other vehicles that do not travel on public streets or highways are generally termed off-highway vehicles, including tractors, forklifts, cranes, backhoes, bulldozers, and golf carts. Off-road vehicles have an enthusiastic following because of their versatility. Several types of motorsports involve racing off-road vehicles. The most common use of these vehicles is for sightseeing in areas distant from the pavement. The use of higher clearance and higher traction vehicles enables access on trails and forest roads that have rough and low traction surfaces. Off-road vehicles can typically ford through deeper waters (i.e., rivers or floodwaters) than on-road vehicles can. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
