Punotia
''Punotia'' is a monotypic genus of flowering plants belonging to the family Cactaceae. The only species is ''Punotia lagopus''. Description ''Punotia lagopus'' grows in dense, large cushions up to over 1 meter in diameter and 60 centimeters high. Its short, cylindrical, bumpy, and densely hairy shoots can reach up to 25 centimeters or more, sometimes shorter and spherical. Fine hairs up to 2 centimeters long emerge from the areoles in a single row. Sparse, white, slightly sloping glochids are 1 to 1.5 centimeters long. Leaf rudiments, up to 7 millimeters long, are hidden among the hairs. A single yellow spine is 2 to 2.5 centimeters long. The golden yellow flowers are 2 to 3 centimeters long, with hairy pericarpels towards the tip. The egg-shaped, thin-walled fruits are light yellow-green before ripening to light pink. Distribution The species is found in the highlands of Peru in the region of Puno around Imata and Arequipa to the department of La Paz in Bolivia, growing in humi ...

Monotypic Genus
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactaceae
A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. 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. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of ''Rhipsalis baccifera'', which is also found in Africa and Sri Lanka. Cacti are adapted to live in very dry environments, including 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 ...

Arequipa
Arequipa (; Aymara language, Aymara and ), also known by its nicknames of ''Ciudad Blanca'' (Spanish for "White City") and ''León del Sur'' (Spanish for "South's Lion"), is a city in Peru and the capital of the eponymous Arequipa (province), province and department of Arequipa, department. It is the seat of the Constitutional Court of Peru and often dubbed the "legal capital of Peru". It is the second most populated city in Peru, after the capital Lima, with an urban population of 1,296,278 inhabitants according to the 2017 national census. known for its colonial architecture and volcanic stone buildings, it is a major cultural and economic center. Its metropolitan area integrates twenty-one districts, including the foundational central area, which it is the seat of the city government. The city had a nominal GDP of US$9,445 million, equivalent to US$10,277 per capita (US$18,610 per capita PPP) in 2015, making Arequipa the city with the second-highest economic activity in Peru ...

Karl Moritz Schumann
Karl Moritz Schumann (17 June 1851 – 22 March 1904) was a German botanist. Schumann was born in Görlitz. He was curator of the Berlin-Dahlem Botanical Garden and Botanical Museum, Botanisches Museum in Berlin-Dahlem from 1880 until 1894. He also served as the first chairman of the ''Deutsche Kakteen-Gesellschaft'' (German Cactus Society) which he founded on 6 November 1892. He died in Berlin. Karl Moritz Schumann participated as a collaborator in ''Die Natürlichen Pflanzenfamilien'' by Adolf Engler and K. A. E. Prantl and in ''Flora Brasiliensis'' by Carl Friedrich Philipp von Martius. The genera ''Schumannianthus'' (François Gagnepain, Gagnepain), ''Schumanniophyton'' (Hermann Harms, Harms), ''Schumannia'' (Otto Kuntze, Kuntze) and several species were named after him, including: Bibliography * Schumann, K. M., "''Gesamtbeschreibung der Kakteen''" (Complete description of cacti), 1898. * Schumann, K. M., et al., "''Kakteen (Iconographia Cactacearum) im Auftrage de ...
