Carlo Luigi Spegazzini
Carlo Luigi Spegazzini, in Spanish Carlos Luis Spegazzini (20 April 1858 – 1 July 1926), was an Italian-born Argentinian botanist and mycologist. On the 1881/1882 expedition led by Giacomo Bove to explore Patagonia and Tierra del Fuego, the Italian Decio Vinciguerra was officially both zoologist and botanist, but in fact Spegazzini handled the botanical work. Spegazzini published about 100 scientific papers on vascular plants, describing around 1000 new taxa. He was a professor at the University of La Plata and Buenos Aires in Argentina, curator of the herbarium of the National Department of Agriculture, first head of the herbarium of Museo de la Plata, and founder of an arboretum and an institute of mycology in La Plata city. In 1924 he edited the journal ''Revista Argentina de Botánica'', but only four issues were published before his death. In a 1924 ''Mycologia'' publication, William Murrill recounted his time visiting with Spegazzini, who was then 66 years old: Dr Sp ...

Portulaca Oleracea
''Portulaca oleracea'' (common purslane, also known as little hogweed, or pursley) is an annual (actually tropical perennial in USDA growing zones 10–11) succulent in the family Portulacaceae. Description The plant may reach in height. It has smooth, reddish, mostly prostrate stems and the leaves, which may be alternate or opposite, are clustered at stem joints and ends. The yellow flowers have five regular parts and are up to wide. Depending upon rainfall, the flowers appear at any time during the year. The flowers open singly at the center of the leaf cluster for only a few hours on sunny mornings. The tiny seeds are formed in a pod, which opens when the seeds are mature. Purslane has a taproot with fibrous secondary roots and is able to tolerate poor soil and drought. The fruits are many-seeded capsules. Seed set is considerable; one plant can develop up to 193,000 seeds. The seeds germinate optimally at a temperature above 25 °C; they are light germinators, with ...

Flora Of South America
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
