Ekmania (echinoderm)
''Ekmania'' is a genus of flowering plants in the family Asteraceae. It contains only one known species, ''Ekmania lepidota'', endemic to Cuba.Gleason, Henry Allan. 1919.

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 ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuba
Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos. Cuba is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both the American state of Florida and the Bahamas, west of Hispaniola ( Haiti/Dominican Republic), and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The official area of the Republic of Cuba is (without the territorial waters) but a total of 350,730 km² (135,418 sq mi) including the exclusive economic zone. Cuba is the second-most populous country in the Caribbean after Haiti, with over 11 million inhabitants. The territory that is now Cuba was inhabited by the Ciboney people from the 4th millennium BC with the Gua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vernonieae
Vernonieae is a tribe of about 1300 species of plants in the aster family. They are mostly found in the tropics and warmer temperate areas, both in the Americas and the Old World. They are mostly herbaceous plants or shrubs, although there is at least one tree species, ''Vernonia arborea''. Taxonomy Vernonieae is considered sister to the tribe Liabeae. The tribe originated in southern Africa or Madagascar, and spread to the Americas in at least two different events. In many works some 80% of the species in this tribe are classified in the genus ''Vernonia''. Other authors, like Harold E. Robinson Harold Ernest Robinson (May 22, 1932 – December 17, 2020) was an American botanist and entomologist. Career Robinson's specialty was the sunflower family (Asteraceae) and the bryophytes. He has named or described over 2,800 new species and ..., divide the tribe into a larger number of small genera. References External links * Asteraceae tribes {{Astera ...
