Panamint Liveforever
''Dudleya saxosa'' is a perennial succulent plant species in the family Crassulaceae, within the genus ''Dudleya'', which are commonly known as ''liveforevers''.Mojave Desert Wildflowers, Pam MacKay, 2nd ed., 2013, This species is a complex of 3 subspecies of plants, isolated and disjunct in distribution from one another, each with varying levels of ploidy and morphology. One plant is native throughout the deserts and mountains of Southern California, another is found in the Panamint Mountains, and one is found throughout central Arizona. Description ''Dudleya saxosa'' is plant that grows from a rosette of fleshy leaves, which may be flat and blade-shaped to somewhat cylindrical. It bolts one or more erect stems which are usually dull pink to red in color, sometimes with pale green coloration. Atop the stems are compact inflorescences of flowers with bright yellow petals.

Dudleya Saxosa Subsp
''Dudleya'', commonly known as liveforevers ( Spanish: ''siemprevivas'') is a genus of succulent plants in the stonecrop family, Crassulaceae, consisting of about 68 taxa in southwestern North America and Guadalupe Island. The species come in multiple divergent forms, some large and evergreen, others cryptic and deciduous, but despite their dramatic variations in appearance, most species readily hybridize. The flowers of ''Dudleya'' have parts numbered in 5, with the petals arranged in tubular, star-shaped, and bell-shaped forms, and when fruiting are filled with tiny, ovoid to crescent-shaped seeds. The genus evolved as neoendemics, from ancestors in the stonecrop genus, '' Sedum.'' The ancestors radiated southward from ''Sedum'' during the creation of the dry summer climate in the California region 5 million years ago. Early botanists classified the larger species as '' Echeveria'' and ''Cotyledon'', while the cryptic species were placed as ''Sedum''. Taxonomic efforts star ...

Peninsular Ranges
The Peninsular Ranges (also called the Lower California province) are a group of mountain ranges that stretch from Southern California to the southern tip of the Baja California peninsula; they are part of the North American Coast Ranges, which run along the Pacific Coast from Alaska to Mexico. Elevations range from . Geography The Peninsular Ranges include the Santa Ana Mountains, Temescal and other mountains and ranges of the Perris Block, San Jacinto and Laguna ranges of southern California continuing from north to south with the Sierra de Juárez, Sierra de San Pedro Mártir, Sierra de San Borja, Sierra de San Francisco, Sierra de la Giganta, and Sierra de la Laguna in Baja California.

Natural History Of The Mojave Desert
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the 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 φύσις by pre-Socr ...

Flora Of The California Desert Regions
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] |

Dudleya Alainae
''Dudleya saxosa'' subsp. ''aloides'' is a species of perennial succulent plant in the family Crassulaceae known by the common names desert dudleya or desert savior. It is a rosette-forming species widely distributed throughout the Peninsular Ranges and desert mountains of California in the United States. It is characterized by bright-yellow or greenish-yellow flowers, and can be found in shaded crevices and slopes. Plants in western half of the range may grade into ''Dudleya lanceolata''. Description A rosette-forming succulent that may be evergreen or summer deciduous. It typically has bright yellow or green flowers. This plant's basal rosette is formed on top of a caudex (stem), which is 1 to 3 cm in diameter. There are 1 to 4 rosettes, and they may be 6 to 23 cm wide. The leaves are typically 4 to 15 cm long, and 6 to 25 mm wide, 2 to 5 mm thick, and their base is 10 to 25 mm wide. The inflorescence has a peduncle 10 to 51 cm tall, a ...

Death Valley
Death Valley is a desert valley in Eastern California, in the northern Mojave Desert, bordering the Great Basin Desert. During summer, it is the Highest temperature recorded on Earth, hottest place on Earth. Death Valley's Badwater Basin is the point of lowest elevation in North America, at below sea level. It is east-southeast of Mount Whitney — the highest point in the contiguous United States, with an elevation of 14,505 feet (4,421 m). On the afternoon of July10, 1913, the National Weather Service, United States Weather Bureau recorded a high temperature of 134 °F (56.7 °C) at Furnace Creek, California, Furnace Creek in Death Valley, which stands as the Highest temperature recorded on Earth, highest ambient air temperature ever recorded on the surface of the Earth. This reading, however, and several others taken in that period are disputed by some modern experts. Lying mostly in Inyo County, California, near the border of California and Nevada, in the Great ...

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 ...
