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] |

Some taxonomists place it in the separate genus ''Idria''. It is nearly endemic to the Baja California Peninsula (both the northern and southern states), with only a small population in the Sierra Bacha of Sonora, Mexico. The plant's English name, Boojum, was given by Godfrey Sykes of the Desert Laboratory in Tucson, Arizona and is taken from Lewis Carroll's poem " The Hunting of the Snark". Description This plant is a columniform, upwardly tapering tree. The central axis of the plant is homologous to the single stem of other species. It has a cortical water-storage network, a feature unique to the family. The ''Fouquieria columnaris'' trunk is up to 24 inches (61 centimeters) thick, off-white in color, with few or no major branches and with numerous thin, twiggy branches sticking out at right angles, all covered with sm ...

Cylindropuntia Cholla
''Cylindropuntia'' is a genus of cacti ( family Cactaceae), containing species commonly known as chollas, native to northern Mexico and the Southwestern United States. They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Stands of cholla are called cholla gardens. Individuals within these colonies often exhibit the same DNA, as they were formerly tubercles of an original plant.
