Echinopsis Chalaensis
''Echinopsis chalaensis'', is a species of ''Echinopsis'' found in Peru. Description ''Echinopsis chalaensis'' grows as a shrub with several upright branches and reaches heights of up to 4 meters. The cylindrical shoots have a diameter of up to 15 centimeters. There are eight broad ribs that are furrowed transversely above the areoles. The areoles on it stand in the notches. Dark brown spiness emerge from them and become lighter with age. The two to three central spines are up to 5 centimeters long with six to ten radial spines are up to 1 centimeter long. The funnel-shaped, white flowers open at night. They grow up to 17 centimeters long and have a diameter of 10 centimeters. Distribution ''Echinopsis chalaensis'' is common in the Arequipa region of Peru on coastal hills, where it is often found hanging from rocks.

Echinopsis
''Echinopsis'' is a large genus of cacti native Native may refer to: People * Jus soli, citizenship by right of birth * Indigenous peoples, peoples with a set of specific rights based on their historical ties to a particular territory ** Native Americans (other) In arts and entert ... to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. One small species, ''E. chamaecereus'', is known as the peanut cactus. The 128 species range from large and treelike types to small globose cacti. The name derives from ''echinos'' hedgehog or sea urchin, and ''opsis'' appearance, a reference to these plants' dense coverings of spines. They are remarkable for the great size, length of tube, and beauty of their flowers, which, borne upon generally small and dumpy stems, appear much larger and more attractive than would be expected. Taxonomy Studies in the 1970s and 1980s resulted in several formerly separate genera being absorbed into '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Curt Backeberg
Curt Backeberg (2 August 1894 in Lüneburg, Germany – 14 January 1966) was a German horticulturist especially known for the collection and classification of cacti. Biography He travelled extensively through Central and South America, and published a number of books on cacti, including the six-volume, 4,000-page ''Die Cactaceae'', 1958–1962, and the ''Kakteenlexikon'', first appearing in 1966 and updated posthumously. Although he collected and described many new species and defined a number of new genera, much of his work was based on faulty assumptions about the evolution of cacti and was too focused on geographic distribution; many of his genera have since been reorganized or abandoned. The botanist David Hunt is quoted as saying that he "left a trail of nomenclatural chaos that will probably vex cactus taxonomists for centuries.", p. 98 Nevertheless, his observations regarding the subtle variations among cacti have proven useful for hobbyists, who continue to use many cactu ...
