Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthocalycium
''Acanthocalycium'' is a genus of cactus consisting of several species from Argentina. The taxon name comes from Greek ''akantha'' (meaning ''prickly'') and ''kalyx'' (meaning ''buds''), which refers to the spines on the floral tubes. These plants are globose to elongate, with numerous ribs on the spiny stems. Flowers range from white to pink to red and open during the day. Taxonomy ''Spinicalycium'' Fric (nom. inval.) has been brought into synonymy with this genus. Besides, the genus ''Acanthocalycium'' has been periodically included in the genus ''Echinopsis ''Echinopsis'' is a large genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. One small species, ''E. chamaecereus'', is known as the peanut cactus. The 128 species range from l ...''. Species References * Edward F.
