Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armatocereus
''Armatocereus'' (from Latin ''armatus'', "armed" and ''cereus'', "pliant/soft") is a genus of mostly tree-like cacti from South America (Ecuador and Peru). These species have a conspicuous constriction at the end of the annual growth. The flowers are mostly white, with a more or less spiny ovary. The fruits are mostly spiny. Description ''Armatocereus'' species are columnar cacti, bushlike or treelike, with cylindrical upright branched stems. The stems have 5–12 distinct ribs, and are made up of sections with a narrower "neck" between them, corresponding to annual growth. The large areoles bear strong spines, rarely few or none. The narrow tubular flowers appear at night, and have a spiny ovary and floral tube and white petals (red in '' A. rauhii''). The red or green fruit is large, globular or ovoid, with strong spines that are lost on maturity. It contains large black seeds, ovoid or kidney-shaped.
