Nathaniel Lord Britton
Nathaniel Lord Britton (1859 – 1934) was an American botanist and taxonomist who co-founded the New York Botanical Garden in the Bronx, New York (state), New York. Early life Britton was born on the 15 of January 1859 at New Dorp, Staten Island, New Dorp, Staten Island, New York, Richmond County, New York (state) to Jasper Alexander Hamilton Britton and Harriet Lord Turner. His parents wanted him to study religion, but he was attracted to nature study at an early age. He was a graduate of the School of Engineering and Applied Science (Columbia University), Columbia University School of Mines and afterwards taught geology and botany at Columbia University. He joined the Torrey Botanical Society, Torrey Botanical Club soon after graduation and was a member his entire life. Britton was an elected member of the United States National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society. He married Elizabeth Gertrude Britton, Elizabet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Colombia
The Flora of Colombia is characterized by over 32,000 species of green plants. National Flower of Colombia The national flower of Colombia is the orchid '' Cattleya trianae'' which was named after the Colombian naturalist José Jerónimo Triana. The orchid was selected by botanist Emilio Robledo, in representation of the Colombian Academy of History to determine the most representative flowering plant of Colombia. He described it as one of the most beautiful flowers in the world and selected ''Cattleya trianae'' as National symbol. National Tree of Colombia The national tree of Colombia is the palm '' Ceroxylon quindiuense'' (Quindío wax palm) which was named after the Colombian Department of Quindío where is located the Cocora valley, the only habitat of this restricted range species. The Quindío wax palm was selected as the national tree by the government of Belisario Betancur and was the first tree officially declared as a protected species in Colombia. ''C.quindi ...

Flora Of Chile
The native flora of Chile is characterized by a higher degree of endemism and relatively fewer species compared to the flora of other countries of South America. A classification of this flora necessitates its division into at least three general zones: the desert provinces of the north, Central Chile, and the humid regions of the south. Northern Chile The first is an arid desert(Atacama desert) absolutely barren along part of the coast, between Arica and Copiapó, but with a coarse scanty vegetation near the Cordilleras along watercourses and on the slopes where moisture from the melting snows above percolates through the sand. The altiplano of the northernmost portion of the Chilean territory is home to the '' Browningia candelaris'', a candelabrum-shaped cactus. Another cactus species, the '' Echinopsis atacamensis'', grows in the pre-Andean area. The high Andean region is also characterized by the presence of species of the genus '' Polylepis'' and the '' Azorella compacta ...

Flora Of Argentina
The environment of Argentina is highly biodiverse. Biodiversity Flora Subtropical plants dominate the Gran Chaco in the north, with the '' Dalbergia'' genus of trees well represented by Brazilian rosewood and the quebracho tree; also predominant are the wacho white and black algarrobo trees ('' Prosopis alba'' and ''Prosopis nigra''). Savannah-like areas exist in the drier regions nearer the Andes. Aquatic plants thrive in the wetlands of Argentina. In central Argentina the ''humid pampas'' are a true tallgrass prairie ecosystem. In Argentina forest cover is around 10% of the total land area, equivalent to 28,573,000 hectares (ha) of forest in 2020, down from 35,204,000 ha in 1990. In 2020, naturally regenerating forest covered 27,137,000 ha and planted forest covered 1,436,000 ha. Of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 7% o ...

Cacti Of South America
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 ...

Cactoideae Genera
The Cactoideae are the largest subfamily of the cactus family, Cactaceae, and are widely distributed throughout the Americas. Cactaceae is the 5th most endangered plant or animal family evaluated globally by the International Union for Conservation of Nature. Around 80% of cactus species belong to this subfamily. The genera of the Cactoideae are characterized by microscopic foliage leaves. All photosynthesis occurs in shoot cortex cells covered by a persistent epidermis and stomata. Another important characteristic of this subfamily is ribbed stems, which enable the inner cortex to expand radially without breaking the shoot surface to absorb large quantities of water.Mauseth, J. D. (2006). Structure–function relationships in highly modified shoots of Cactaceae. ''Annals of Botany, 98''(5), 901-926. , the internal classification of the family (biology), family Cactaceae remained uncertain and subject to change.
