Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

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 ...
