Turbinicarpus Booleanus - Flickr - Resenter89
''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.

Echinocactus
''Echinocactus'' is a genus of cacti in the subfamily Cactoideae. The generic name derives from the Ancient Greek εχινος (''echinos''), meaning "spiny," and ''cactus''. It and ''Ferocactus'' are the two genera of barrel cactus. Members of the genus usually have heavy spination and relatively small flowers. The fruits are copiously woolly, and this is one major distinction between ''Echinocactus'' and ''Ferocactus''. Propagation is by seed. Perhaps the best known species is the golden barrel (''Echinocactus grusonii'') from Mexico, an easy-to-grow and widely cultivated plant. Though common in the houseplant and landscape industry, the golden barrel has become very rare in habitat. Species As of 2020, the genus includes 6 accepted species out of hundreds of plants having the name. Formerly placed here *''Astrophytum asterias'' (Zucc.) Lem.

Polyphyly
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with system ...

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 ...

Toumeya
''Sclerocactus'' ("hard cactus", from Greek; refers to the hard, dry fruit) is a genus of cacti. It comprises about 15 species, the exact number depending on the authority. These species are very xerophytic. They are sometimes called 'fishhook cactus' or 'little barrels.' Description ''Sclerocactus'' are ovoid to elongate cylindric, have rigid stems with tubercles that are generally coalesced into ribs, and are covered with spines that come out of the areoles., in Most species have at least one hooked spine at each areole. Less often, species may not have hooks. These plants are found in higher elevation deserts such as on the Colorado Plateau, or in the Mohave Desert or the Great Basin. They are well suited to extremes due to lack of rainfall, hot summers and below freezing winters. The little barrel cactus typically grows in areas where water flows irregularly or depressions where water can accumulate for short periods of time. They are most often found growing along w ...

Thelocactus
''Thelocactus'' is a genus of flowering plants in the cactus family Cactaceae. Members of the genus are native to the arid lands of Central and Northern Mexico. Description ''Thelocactus'' species are globe-shaped, short and cylindrical. They are small cacti, although there are one or two species which, while only about 15 cm high, can be 25 cm in diameter; for example, ''T. nidulans''. ''Thelocactus'' species are generally solitary, but some varieties will cluster in groups. The ribs on ''Thelocactus'' species are very clearly marked and are sometimes twisted in a spiral. There can be from 8 to 20 ribs, which are rather low and normally marked with raised, angular or hexagonal tubercles. These tubercles can sometimes be difficult to distinguish. Areoles sit in a furrow directly above where the spines grow and there can be up to twenty radial/radiating spines. They are often needle-like, spread out and can be from 1.3 – 1.5 cm long. The central spines are most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strombocactus
''Strombocactus disciformis'' is a rare species of cacti and the only species of the genus ''Strombocactus''. The plant originates from Central and Northeast Mexico. Description ''Strombocactus'' is a monotypic genus with a strong turnip-like root, a small, depressed, roughly spherical stem covered with spirally arranged overlapping tubercles, each with a spine-bearing areole at its tip. Flowers come from new growth at the crown, and the cactus's small seeds are difficult to see with the naked eye. Taxonomy The species has several forms and subspecies: *''Strombocactus disciformis'' f. ''cristata'' *''Strombocactus disciformis'' ssp. ''esperanzae'' Conservation status Both subspecies arclassified as Vulnerableon the IUCN Red List, which states that it has a limited range and "is experiencing a decline in mature individuals due to illegal overcollection".

''Pediocactus'' ( Greek: πεδίον (pedion) means "plain", "flat", "field") is a genus of cacti. The genus comprises between 6 and 11 species, depending upon the authority. Species of this genus are referred to as hedgehog cacti, though that name is also applied to plants from the genera '' Echinocereus'' and '' Echinopsis''.

Neolloydia
''Neolloydia'' is a formerly recognized genus of cacti. The genus was first erected by Britton and Rose in 1922. Edward F. Anderson regarded ''Neolloydia'' as being poorly defined, with the result that species that had at times been included in ''Neolloydia'' were afterwards placed in multiple genera, including ''Coryphantha'', ''Echinomastus'', '' Escobaria'', '' Mammillaria'', ''Sclerocactus'', ''Thelocactus'' and '' Turbinicarpus''. In his 2001 book, Anderson firmly placed only one species in the genus, ''Neolloydia conoidea'', with another, ''Neolloydia matehualensis'', being regarded as only a variant of ''N. conoidea''. , Plants of the World Online treated ''Neolloydia conoidea'' as a synonym of ''Cochemiea conoidea'', and ''Neolloydia'' as a synonym of ''Cochemiea''. Species that have been placed in ''Neolloydia'' include: *''Neolloydia clavata'' → ''Coryphantha clavata'' *''Neolloydia conoidea'' → ''Cochemiea conoidea'' *''Neolloydia horripila'' → ''Kadenicarpu ...
