Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ...

Cryptanthus
''Cryptanthus'' is a genus of flowering plants in the family (biology), family Bromeliaceae, subfamily Bromelioideae. The genus name is from the Greek ''cryptos'' (hidden) and ''anthos'' (flower). The genus formerly had two recognized subgenera: the type subgenus and subgenus ''Hoplocryptanthus'' Mez which has been raised to the separate genus ''Hoplocryptanthus''. All species of this genus are Endemism, endemic to Brazil. The common name for any ''Cryptanthus'' is "Earth star". Species , Plants of the World Online accepted the following species: *''Cryptanthus acaulis'' (Lindl.) Beer *''Cryptanthus alagoanus'' Elton Leme, Leme & J.A.Siqueira *''Cryptanthus apiculatantherus'' D.M.C.Ferreira, E.M.Almeida & Louzada *''Cryptanthus bahianus'' L.B.Sm. *''Cryptanthus beuckeri'' É.Morren *''Cryptanthus bibarrensis'' Leme *''Cryptanthus bivittatus'' (Hook.)

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...
