Rapicactus
''Rapicactus'' is a genus of cactus in the tribe Cacteae, subfamily Cactoideae. It has been synonymized with ''Turbinicarpus'' but molecular phylogenetic studies have supported its monophyly and separation from that genus. Taxonomy The genus ''Rapicactus'' was proposed in 1942 by Buxbaum and Oehme. It was characterized by having thick roots with a constriction above forming a neck. However, most subsequent treatments sank the genus into a broadly circumscribed genus ''Turbinicarpus''. The circumscription of ''Turbinicarpus'' has been described as "remarkably unstable", with species regularly transferred to other genera. The broad circumscription of ''Turbinicarpus'' was recognized as polyphyletic by Hunt in 2016. A phylogenetic study published in 2019 showed that a monophyletic ''Rapicactus'' was sister to ''Acharagma'', separated from a monophyletic ''Turbinicarpus'': Species , Plants of the World Online Plants of the World Online (POWO) is an online database published by th ...

Turbinicarpus
''Turbinicarpus'' is a genus of very small to medium-sized cacti, which inhabit the north-eastern regions of Mexico, in particular the states of San Luis Potosí, Guanajuato, Nuevo León, Querétaro, Hidalgo, Coahuila, Tamaulipas and Zacatecas. Taxonomy The taxon was first proposed by Curt Backeberg as ''Strombocactus'' subgenus ''Turbinicarpus''. It was elevated to a genus in 1937 by Franz Buxbaum and Backeberg. The circumscription of ''Turbinicarpus'' has been described as "remarkably unstable", with species regularly transferred to other genera. Its taxonomic history is often mixed with that of other genera like ''Echinocactus'', ''Echinomastus'', '' Gymnocactus'', ''Mammillaria'', ''Neolloydia'', ''Normanbokea'', ''Pediocactus'', ''Pelecyphora'', '' Strombocactus'', ''Thelocactus'' and '' Toumeya'', as the results of almost two centuries of constant evolution in the understanding of the affinities and relationships inside the family Cactaceae.

Cacteae
Cacteae is a tribe of plants of the family Cactaceae found mainly in North America especially Mexico. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Description The spherical to short columnar plants grow individually or in cushions. Their size varies from dwarf (''Turbinicarpus'') to huge (''Ferocactus''). The non-segmented shoot axis is ribbed (''Echinocactus''), warty (''Coryphantha'') or ribbed-warty. The size and shape of the warts ranges from long and leafy ('' Leuchtenbergia'') to broad with flat axillae (''Turbinicarpus''). The areoles are usually oval, ribbon-like, grooved, or dimorphic. The small to medium-sized, regular to rarely bilaterally symmetrical flowers appear below the crown and open during the day. The fruits are fleshy to juicy berry-like, with a scaly to glabrous pericarp. They are bursti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactoideae
The Cactoideae are the largest subfamily of the cactus family, Cactaceae. Around 80% of cactus species belong to this subfamily. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Various revisions have been published since, e.g. to the tribe Hylocereeae and the tribe Echinocereeae. Classifications remained uncertain . Tribes and genera , the National Center for Biotechnology Information used the division of the subfamily into tribes shown below. Some revisions to the circumscriptions of the tribes are also shown. *Blossfeldieae **''Blossfeldia'' * Browningieae **''Armatocereus'' – ''Browningia'' – ''Neoraimondia'' – '' Stetsonia'' *Cacteae **''Acharagma'' – ''Ariocarpus'' – '' Astrophytum'' – ''Aztekium'' – ''Coryphantha'' – '' Cumarinia'' – ''Echino ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...
