Dudleya Pachyphytum
''Dudleya pachyphytum'' is an insular succulent plant known by the common name Cedros Island liveforever. It is a member of the genus ''Dudleya,'' in the family Crassulaceae. Characterized by thick, blunt leaves covered in a white, powdery wax and adorned by white flowers in bloom, it is regarded as one of the most attractive and charismatic members of its genus. It is endemic to the foggy northern end of Mexico's Cedros Island, occupying an ecological niche shared with the Cedros Island Pine. The plant is endangered due to poaching from organized criminals supplying succulent collectors, many of whom are located in Asia. The poachers include South Korean nationals and criminal gangs operating under the Mexican cartels. The demand from succulent collectors has led to overexploitation of the plant in the wild, and armed confrontations between competing poachers has contributed to several killings.

Dudleya Cedrosensis
''Dudleya cochimiana'', commonly known as the Cedros liveforever, is a species of succulent plant in the family Crassulaceae endemic to Cedros Island, a large island off of the coast of Baja California, Mexico. It is a rosette-forming leaf succulent characterized by broad, green to white leaves, and flowers with white to pink petals. It can be found on rocky slopes and canyons along the island. Taxonomy This species was first known as ''Dudleya cedrosensis,'' a name given to the plants by Reid Moran Reid Venable Moran (June 30, 1916 – January 21, 2010) was an American botanist and the curator of botany at the San Diego Natural History Museum from 1957 to 1982. Moran was the world authority on the Crassulaceae, a family of succulent plant ... in his 1951 thesis on ''Dudleya''. The failure of the thesis to be published meant that ''Dudleya cedrosensis'' was never a valid species, as Moran had difficulty reconciling some morphological differences between plants on the isla ...

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant families have varieties with rosette morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern '' Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plant. Function in flowering plants Often, rosettes form in perennial plants whose upper foliage dies back with the remaining vegetation protecting the plant. Ano ...

Decimetre
The decimetre (symbol dm) or decimeter (American English) is a unit of length in the International System of Units (SI), equal to one tenth of a metre, ten centimetres, 100 millimetres or 3.937 inches. The common non-SI metric unit of volume, the litre, is defined as one cubic decimetre, although, from 1901 to 1964, there was a slight difference between the two due to the litre being defined using the kilogram rather than the metre. See also *Metric prefix *Deci- * *Conversion of units Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors which change the measured quantity value without changing its effects.

Channel Islands (California)
The Channel Islands () are an eight-island archipelago located within the Southern California Bight in the Pacific Ocean, off the coast of California. The four Northern Channel Islands are part of the Transverse Ranges geologic province, and the four Southern Channel Islands are part of the Peninsular Ranges province. Five of the islands are within the Channel Islands National Park, and the waters surrounding these islands make up Channel Islands National Marine Sanctuary. The Nature Conservancy was instrumental in establishing the Channel Islands National Marine Sanctuary. The islands were inhabited as early as 13,000 years ago, the earliest paleontological evidence of humans in North America. They are the easternmost islands in the Pacific Island group. The Chumash and Tongva Native Americans who lived later on the islands may be the descendants of the original inhabitants, but they were then displaced by Spaniards who used the islands for fishing and agriculture.

Dudleya Greenei
''Dudleya greenei'' is a perennial species of succulent plant known by the common names Greene's liveforever, or Greene's dudleya. It is endemic to the Channel Islands of California, where it grows along the cliffs of four of the eight islands. It is a highly variable plant,McCabe, S. (1997). ''Dudleya gnoma'' (Crassulaceae): A new species from Santa Rosa Island. ''Madroño'' 44 48-58. presenting with multiple forms and varying levels of ploidy. Taxonomically, this species is an insular segregate of ''Dudleya caespitosa'', and was placed as a stopgap taxon by Reid Moran in his 1951 thesis on the genus. It is characterized by white or green leaf rosettes, loomed over by inflorescences bearing pale yellow to white flowers. It is a member of the subgenus ''Dudleya'', as it cannot be propagated from leaf cuttings, does not grow from a corm, and has tight petals. Description Morphology This species of ''Dudleya'' may or may not be caespitose; it can form clumps up to 1 meter wid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Coast (California)
The North Coast of California (also called the Redwood Empire or the Redwood Coast in reference to the dense redwood forests throughout the region) is a region in Northern California that lies on the Pacific coast between San Francisco Bay and the Oregon border. It commonly includes Mendocino, Humboldt, and Del Norte counties and sometimes includes two counties from the San Francisco Bay area, Marin and Sonoma. Cities Much of the area is rural, and it contains few major cities. The only city with a population of over 100,000 is Santa Rosa (population 178,000) in Sonoma County, which is the largest city of the North Coast under the five-county definition. Eureka (population 27,000) in Humboldt County is the largest under the three-county definition. Despite their relatively smaller size to the major cities elsewhere in the state, many of the region's cities and towns have historical importance to the state or regional importance.

Dudleya Farinosa
''Dudleya farinosa'' is a species of succulent plant in the family Crassulaceae known by several common names, including bluff lettuce, powdery liveforever, and powdery dudleya. A coastal plant of northern California and southern Oregon, it is typically found on oceanic bluffs just directly above the reach of the waves. Its appearance is characterized by lotus-like rosettes of beveled leaves, and in summer the plant erects a tall pink to red stem densely covered in foliage, topped with branches adorned with pale yellow flowers. The green or white rosettes of this plant can be seen covering stretches of rocky coast and nearby islets. Although quite common in its habitat, in recent years human interactions with the plants have led to devastating reversals in populations susceptible to poaching. The characteristic appearance of this plant makes it highly desirable for plant poachers, who illegally dig up plants in large numbers and ship them to East Asia, where they are in high demand ...

Coronado Islands
The Coronado Islands (''Islas Coronado'' or ''Islas Coronados''; en, Islands of the Coronation(s); Kumeyaay: Mat hasil ewik kakap) are a group of islands located off the northwest coast of the Mexican state of Baja California. Battered by the wind and waves, the rocky islands are mostly uninhabited except for a small military detachment and a lighthouse keeper. Despite their barren appearance, they serve as a refuge for seabirds and support a sizable number of plants, including 6 endemic taxa found only on the islands. The waters around the islands support a considerable amount of diverse marine life. Used extensively and intermittently by the indigenous peoples for thousands of years, the first European explorers sighted them in 1542. Centuries later, they served as weekend getaway locations, secret gambling spots, and smuggling sites until the Mexican Navy clamped down on trespassing. The tied island city of Coronado, California, to the north, was named in honor of the islan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dudleya Candida
''Dudleya candida'' is a species of perennial succulent plant in the family Crassulaceae known by the common names Coronados liveforever or chalk rose. It is a rosette-forming, green to white-colored leaf succulent, and in bloom yellow flowers atop red stalks stand above the foliage. It has some visual similarities to the mainland ''Dudleya brittonii'', and has found uses in horticulture as an ornamental plant. It is restricted to the Coronado Islands, an island group off of the extreme northern Baja California coast, visible from the United States. Description Beginning from the bottom, the caudex is 2.5 cm (1 in) to 5 cm (2 in) thick, and quickly branches into rounded mounds over (2 ft) in diameter, containing sometimes over 200 rosettes that are 7.6 cm (3 in) to 17 cm (7 in) in diameter. The foliage consists of 30 to 60 white, pulverulent leaves, that may have pink or reddish tips. The leaves are often widest at the base, 5 cm (2 in) to 10 cm (4 in) long, 1.2 cm (0.5 in ...

Central Coast (California)
The Central Coast is an area of California, roughly spanning the coastal region between Point Mugu and Monterey Bay. It lies northwest of Los Angeles County and south of San Mateo and Santa Clara counties, and includes the rugged, undeveloped stretch of coastline known as Big Sur. From south to north, there are six counties that make up the Central Coast: Ventura, Santa Barbara, San Luis Obispo, Monterey, San Benito, and Santa Cruz. The Central Coast is the location of the Central Coast American Viticultural Area. Geographically, the actual midpoint of the California coast lies north of Santa Cruz, near Año Nuevo State Park in San Mateo County. Neither the popular use of the term Central Coast nor that of the California North Coast include the San Francisco Peninsula counties of San Mateo and San Francisco. History The Central Coast area was originally inhabited by Chumash and other Native American people since at least 10,000 BC. Many of these communities were co ...

Dudleya Caespitosa
''Dudleya caespitosa'' is a succulent plant known by several common names, including sea lettuce, sand lettuce, and coast dudleya. It is endemic to California, where it grows along the coastline in the southern half of the state. Taxonomically, this species is a highly variable complex of polymorphic and polyploid plants, closely related to numerous neighboring species such as '' Dudleya farinosa'', ''Dudleya greenei'' and ''Dudleya palmeri''. It is delimited from neighboring species on an arbitrary basis of distribution and chromosome number, and may not be immediately separable from the other species it approaches. Description Vegetative morphology This plant may grow in solitary rosettes, but most often forms caespitose clumps, which may contain up to 150+ rosettes. The clumps are generally not dense. Each rosette may be anywhere from 8 to 32 cm wide, containing 15 to 30 leaves. The caudex is 1.5 to 4 cm wide, and on older plants is often exposed between dry ...
