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 ...

Lüneburg
Lüneburg (officially the ''Hanseatic City of Lüneburg'', German: ''Hansestadt Lüneburg'', , Low German ''Lümborg'', Latin ''Luneburgum'' or ''Lunaburgum'', Old High German ''Luneburc'', Old Saxon ''Hliuni'', Polabian ''Glain''), also called Lunenburg ( ) in English, is a town in the German state of Lower Saxony.

Lüneburg's urban area, which includes the surrounding communities of Adendorf, Bardowick, Barendorf and Reppenstedt, has a population of around 103,000. Lüneburg has been allowed to use the title " Hansestadt" (''Hanseatic Town'') in its name since 2007, in recognition of its membership in the former Hanseatic League. Lüneburg is also home to Leuphana University. History ImageSize = width:1050 height:100 PlotArea = width:1000 height:50 left:50 bottom:2 ...

Horticulturist
Horticulture is the branch of agriculture that deals with the art, science, technology, and business of plant cultivation. It includes the cultivation of fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. It also includes plant conservation, landscape restoration, landscape and garden design, construction, and maintenance, and arboriculture, ornamental trees and lawns. The study and practice of horticulture have been traced back thousands of years. Horticulture contributed to the transition from nomadic human communities to sedentary, or semi-sedentary, horticultural communities.von Hagen, V.W. (1957) The Ancient Sun Kingdoms Of The Americas. Ohio: The World Publishing Company Horticulture is divided into several categories which focus on the cultivation and processing of different types of plants and food items for specific purposes.

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 spine ...

Helia Bravo Hollis
Helia Bravo Hollis (30 September 1901 – 26 September 2001) was a Mexican botanist who did research in the Faculty of Science at UNAM. Background and studies Helia Bravo Hollis was born and raised in Mixcoac, located in present-day Mexico City. Her interest in the study of living beings came from Sunday walks with her parents. She excelled in school from a young age. President Porfirio Diaz gave her recognition for her grades upon her completion of primary school. The political turmoil during the Mexican Revolution affected her family. Her father, a loyal supporter of Francisco Madero, was killed in 1914, shortly after Madero's assassination. Despite the conflicts her family faced, she made progress with her studies and entered high school in 1919. Saint Ildefonso ( National Preparatory High School), in Mexico City, was a very interesting institution for her, with teachers like Vicente Lombardo Toledano, Sotero Prieto, Erasmo Castellano, Antonio Caso, and Isaac Ochote ...

Backebergia
''Pachycereus'' is a genus of 9–12 species of large cacti native to Mexico and just into southern Arizona, United States. They form large shrubs or small trees up to 15 m tall, with stout stems up to 1 m in diameter. ''Pachycereus'' comes from the ancient Greek παχύς (''pachys'') meaning "thick" and the Latin ''cereus'' meaning "torch". Species ''P. pringlei'' is the tallest cactus species in the world, with a maximum recorded height of 19.2 m.Salak, M. (2000). In search of the tallest cactus.
