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 ...

Succulent Plant
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaf, leaves and Plant stem, stems. The water content of some succulent organs can get up to 90–95%, such as ''Glottiphyllum semicyllindricum'' and ''Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in Alpine climate, alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crassulaceae
The Crassulaceae (from Latin ''crassus'', thick), also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus ''Sedum'', and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic. Crassulaceae are mainly pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Cedros Island
Cedros Island (''Isla de Cedros'', "island of cedars" in Spanish) is an island in the Pacific Ocean belonging to the state of Baja California, Mexico. The dry and rocky island had a population of 1,350 in 2005 and has an area of which includes the area of several small nearby islands. Cedros Island is mountainous, reaching a maximum elevation of . The economy is based on commercial fishing and salt production. Cedros has a distinctive flora and the traces of some of the earliest human beings in the New World. The ocean around the island is popular with sport fishermen. There was human presence of the island already about 11,000 years ago. The American Indian inhabitants when the island was first visited by Spanish explorers in the 16th century called it Huamalgua, the "Island of Fogs." The Indian inhabitants have been given the name Huamalgueños by modern day scholars. They were relocated to the mainland of Baja California by Jesuit missionaries in 1732 and ceased to exist a ...

Reid Venable 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 plants, and in particular the genus ''Dudleya'', the subject of his Ph.D. dissertation. He named at least 18 plants new to science — some in that family and some not — and published many papers elucidating relationships within the Crassulaceae. As a mark of the respect he earned among his peers, more than a dozen plants have been named for him. Jane Goodall described Moran as "a sort of living myth in botanical exploration in Baja California and the Pacific Islands of Mexico," citing specifically his analysis of the environmental impact of introduced species (especially goats) on the flora of Guadalupe Island. Biography Born in Los Angeles, California on June 30, 1916 to Edna Louise Venable and Robert Breck Moran (a petroleum geologist), Mora ...

Species Affinis
''Species affinis'' (commonly abbreviated to: ''sp.'', ''aff.'', or ''affin.'') is taxonomic terminology in zoology and botany. In open nomenclature it indicates that available material or evidence suggests that the proposed species is related to, has an affinity to, but is not identical to, the species with the binomial name it comes after. The Latin word ''affinis'' can be translated as "closely related to", or "akin to". An author who inserts '' n.sp.,'' or ''sp. nov., aff'' before a species name thereby states the opinion that the specimen is a new, previously undescribed species, but that there may not (yet) be enough information to complete a formal description. To use ''aff.'' alone, implies that the specimen differs suggestively from the holotype but that further progress is necessary to confirm that it is a novel species. An example would be: a gastropod shell listed as ''Lucapina'' aff. ''L.'' ''aegis'' would mean that this shell somewhat resembles the shell of '' Lucapi ...

Cochimí
The Cochimí were the indigenous inhabitants of the central part of the Baja California peninsula, from El Rosario in the north to San Javier in the south. Information on Cochimí customs and beliefs has been preserved in the brief observations by explorers but, above all, in the writings of the Jesuits (Aschmann 1959; Laylander 2000; Mathes 2006). Particularly important and detailed are the works of Miguel Venegas (1757, 1979) and Miguel del Barco (1973). History The Cochimí were first encountered by Spanish seaborne explorers during the sixteenth century, including Ulloa, Cabrillo, Vizcaíno, and others. Sporadic encounters continued until the Jesuits established missions on the peninsula in the late seventeenth century. Eusebio Francisco Kino made an abortive foundation at San Bruno, to the north of Loreto, in 1683-1685. Juan María de Salvatierra began the first successful mission in 1697 at Loreto among the Monqui, who were southern neighbors of the Cochimí. T ...
