Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks.

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''.
