Echinocereus Websterianus (6050284589)
''Echinocereus websterianus'', commonly known as the San Pedro Nolasco hedgehog cactus or Webster's hedgehog cactus, is a species of cactus. It is named after American philanthropist Gertrude Webster, who cofounded the Desert Botanical Garden in Phoenix, Arizona. Description Webster's hedgehog is a short barrel cactus growing up to tall (though usually specimens are shorter) and in diameter. It may grow in a clumping fashion, with up to 50 other basal branches forming the clump. Golden yellow, brown, or white spines grow about long from closely spaced areoles. The pink, violet, or white flower blooms during the day. Flowers are small for the genus, only about in diameter and long from where it branches off the cactus. Flowers do not readily detach once pollinated, which can lead to stem rot. Blooming occurs in the hot months of June and July, once the plant reaches maturity at between 7 and 10 years old. Blooms stay open for 2 or 3 days. Taxonomy This species was first d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Edmund Lindsay
George Edmund Lindsay (1916 – 2002) was an American botanist, naturalist, and museum director. From 1956 to 1963, he was director of the San Diego Natural History Museum and served as Director of the California Academy of Sciences from 1963 to 1982. At both institutions, Lindsay led research field expeditions to the islands in the Sea of Cortez (Vermilion Sea and Gulf of California) found between the Baja California Peninsula and mainland Sonora, Mexico. These expeditions relied on the Vermilion Sea Field Station at Bahia del Los Angeles as their base of operations, which he facilitated and organized. He was active in transnational conservation efforts to protect the islands as biodiversity sanctuaries in the Gulf of California. Biography Lindsay was born in Los Angeles County, in Pomona, California, on August 17, 1916, to orchardists Alice H. Foster and Charles W. Lindsay. He attended Chaffey Junior College (in Ontario, California) and San Diego State College before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spin ...

Desert Botanical Garden
Desert Botanical Garden is a botanical garden located in Papago Park, at 1201 N. Galvin Parkway in Phoenix, central Arizona. Founded by the Arizona Cactus and Native Flora Society in 1937 and established at this site in 1939, the garden now has more than 50,000 plants in more than 4,000 taxa, one-third of which are native to the area, including 379 species, which are rare, threatened or endangered. Of special note are the rich collections of agave (4,026 plants in 248 taxa) and cacti (13,973 plants in 1,320 taxa), especially the Opuntia sub-family. Plants from less extreme climate conditions are protected under shadehouses. It focuses on plants adapted to desert conditions, including an Australian collection, a Baja California collection and a South American collection. Several ecosystems are represented: a mesquite bosque, semi-desert grassland, and upland chaparral. Desert Botanical Garden has been designated as a Phoenix Point of Pride.

Areole
In botany, areoles are small light- to dark-colored bumps on cacti out of which grow clusters of spines. Areoles are important diagnostic features of cacti, and identify them as a family distinct from other succulent plants. Gordon Rowley - What is an Areole The spines are not easily detachable, but on certain cacti, members of the subfamily Opuntioideae, smaller, detachable bristles, glochids, also grow out of the areoles and afford additional protection. Areoles represent highly specialized branches on cacti. Apparently, they evolved as abortive branch buds while their spines evolved as vestigial leaves. In branched cacti, such as Opuntioidiae and the saguaro, new branches grow from areoles, because that is where the buds are. The development of the areole seems to have been an important element in the adaptation of cacti to niches in desert ecology. Some of the Opuntioideae have spines, as well as glochids, on their areoles; some have only glochids. Structurally, the gloc ...

Stem Rot
Stem rot is a disease caused by a fungus infection in the stem. Fungus that causes stem rot are in the ''Rhizoctonia'', ''Fusarium'' or ''Pythium'' genera. Stem rot can readily infect crops that are in their vegetative or flowering stages. The disease can survive up to five years in the soil. Symptoms of stem rot includes staining of infected area, reduced crop yield and crop failure. The disease can be spread through the use of unfiltered water as well as unsterilized tools. Also leaving previous dead roots in soil can increase the risk of stem rot. Spores can also enter the plant through injured stem tissue on the plant including from insect attacks. The fungus impedes stem functions like transporting nutrients. It can cause water to leak through the lesions of stem tissue. Common infected crop plants are soybeans and potatoes. An issue with maintaining this disease is the lack of management by crop producers. Producers of soybeans tend to not manage for the disease because it is ...

San Pedro Nolasco Island
San Pedro Nolasco Island, sometimes called Seal Island, is a small and rugged Mexican island in the Gulf of California. It is 4.2 km long by 1 km wide, and lies 15 km from the nearest point of the Mexican coast and about 28 km west of the resort town of San Carlos on the coast of the Sonoran Desert. The island is protected as a nature reserve and its coastal waters are well known as a sport fishing and diving site. Flora and fauna The island is home to an endemic cactus ''Echinocereus websterianus''. Endemic fauna include the San Pedro Nolasco Island spinytail iguana ('' Ctenosaura nolascensis'') and, formerly, Pemberton's deer mouse (''Peromyscus pembertoni'' ), a rodent which is now extinct. Large numbers of California sea lions frequent its surrounding waters and use the island as a haul-out.

Gulf Of California
The Gulf of California ( es, Golfo de California), also known as the Sea of Cortés (''Mar de Cortés'') or Sea of Cortez, or less commonly as the Vermilion Sea (''Mar Bermejo''), is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately . Rivers that flow into the Gulf of California include the Colorado, Fuerte, Mayo, Sinaloa, Sonora, and the Yaqui. The surface of the gulf is about . Maximum depths exceed because of the complex geology, linked to plate tectonics. The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. Parts of the Gulf of California are a UNESCO World Heritage Site.

Agave Chrysoglossa
''Agave'' (; ; ) is a genus of monocots native to the hot and arid regions of the Americas and the Caribbean, although some ''Agave'' species are also native to tropical areas of North America, such as Mexico. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves. ''Agave'' now includes species formerly placed in a number of other genera, such as ''Manfreda'', ×''Mangave'', ''Polianthes'' and ''Prochnyanthes''. Many plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most ''Agave'' species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Maguey flowers are considered edible in many indigenous culinary traditions of Mesoamerica. Along with plants from the closely related genera ''Yucca'', ''Hesper ...
