Dudleya Anomala
''Dudleya anomala'' is a rare species of succulent plant in the family Crassulaceae commonly known as the Todos Santos liveforever. With a dense, cushion-forming habit, this leaf succulent is characterized by elongated stems, slightly sticky leaves, and bell-shaped flowers with white, spreading petals. This species is native to Baja California, Mexico, and is found primarily on islands and one coastal locality. Description Morphology ''Dudleya anomala'' is a rosette-forming leaf succulent that grows in a caespitose habit, with the stems branching to form dense cushions of rosettes in diameter. The stems are elongated and procumbent, and may reach up to long, and are usually thick. Topping the stems are the rosettes, which contain 20 to 30 close-set leaves, that may become somewhat separated when the stem is rapidly elongating. The leaves are shaped strap-oblanceolate to strap-shaped, with acute tips. The lower surface of the leaf is convex, while the upper surface is ...

Adhesion
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another ( cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are also certain emergent mechanical effects. Surface energy Surface energy is conventionally defined as the work that is required to build an area of a particular surface. Another way to view the surface energy is to relate it to the work required to cleave a bulk sample, creating two surfaces. If the new surfaces are identical, the surface energy γ of each surface is equal to half the work of cleavage, W: γ = (1/2)W11. If the surfac ...

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.

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 ...

Dudleya Lanceolata
''Dudleya lanceolata'' is a succulent plant known by the common name lanceleaf liveforever or lance-leaved dudleya. It is an extremely variable and widely ranging species that occurs from Monterey County and Kern County in California south through Ensenada in Baja California. It is characterized by green to purple lanceolate leaves, red, orange, or less commonly yellow petals, and is typically tetraploid. Despite its diversity, it is quite stable as a species, but hybrids may be discovered with other species of ''Dudleya'', which can make it difficult to discern in areas where numerous species converge. Description Vegetative morphology This plant is a rosette-forming succulent. The rosettes emerge from the apex of the caudex, which may be solitary or apically branched, with anywhere from 1 to 7 rosettes on top. The caudex is 1 to 3 cm wide, less than 4 cm long, but is occasionally elongated. The rosettes are 3 to 25 cm in diameter, and typically with 10 to 25 ...

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 Anthonyi
''Dudleya anthonyi'', known by the common name San Quintín liveforever, is a succulent plant endemic to the San Quintín volcanic field, located on Isla San Martín and the adjacent mainland bay of Bahia San Quintín, within Baja California. Description ''Dudleya anthonyi'' is very similar in appearance to ''Dudleya pulverulenta''.
