Cactoideae Genera
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'' – ''Ech ...

Mammillaria Elongata
''Mammillaria elongata'', the gold lace cactus or ladyfinger cactus, is a species of flowering plant in the family Cactaceae, native to central Mexico. Growing to tall by wide, it consists of densely packed clusters of elongated oval stems, covered in harmless (although very sharp) yellow or brown spines, and in spring producing white or yellow flowers. It is among the most common and most variable of its genus in nature, and is a popular subject for cultivation. It has gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit ....

Astrophytum
''Astrophytum'' is a genus of six species of cacti, native to North America. These species are sometimes referred to as living rocks, though the term is also used for other genera, particularly ''Lithops'' (Aizoaceae). The generic name is derived from the Greek words άστρον (''astron''), meaning "star," and φυτόν (''phyton''), meaning "plant." Description The species of the genus ''Astrophytum'' usually grow individually with spherical to columnar green shoots and reach heights of up to 1.5 meters. The shoots are often densely covered with fine white tufts of hair, but sometimes they are completely bald. There are four to ten (rarely three) very noticeable ribs that are not divided into cusps. The large areoles stand close together, but do not merge. The spike is variable. Spines may be present or may be missing entirely. The funnel-shaped, large flowers are yellow or yellow with a red throat. They appear at the top of the shoots and open during the day. The perica ...

Lophophora
''Lophophora'' () is a genus of spineless, button-like cacti. Its area range covers southern through northeastern and north-central Mexico to Querétaro in central Mexico. The species are extremely slow growing, sometimes taking up to thirty years to reach flowering age (at the size of about a golf ball, excluding the root) in the wild. Cultivated specimens grow considerably faster, usually taking between three and ten years to reach from seedling to mature flowering adult. The slow rate of reproduction and over-harvesting by collectors render the species under threat in the wild. Taxonomy ''Lophophora'' means "crest-bearing", referring to the tufts of trichomes that adorn each tubercle. ''Lophophora'' has been reported to have two species, '' L. diffusa'' and '' L. williamsii''. Another three species have been proposed: ''L. fricii'', ''L. koehresii'', and ''L. alberto-vojtechii''. Recent DNA sequencing studies (Butterworth et al. 2002) have shown that ''L. diffusa'' and ''L. w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leuchtenbergia
''Leuchtenbergia'' is a genus of cactus which has only one species, ''Leuchtenbergia principis'' (agave cactus or prism cactus). It is native to north-central Mexico ( San Luis Potosi, Chihuahua). The genus is named after Maximilian Eugen Joseph (1817–1852), Duke of Leuchtenberg and amateur botanist. It is very slow-growing but can eventually grow up to 70 cm high, with a cylindrical stem which becomes bare and corky at the base with age. It has long, slender, grayish-green tubercles 6–12 cm long, with purplish-red blotches at their tips. The tubercles are topped with papery spines, making the plant resemble an agave; old, basal tubercles dry up and fall off. After four years or so, yellow, funnel-shaped flowers 5–6 cm diameter may be borne at the tubercle tips. The fruit is smooth and green, 3 cm long and 2 cm broad. It has a large, tuberous taproot. Taxonomy It is related to the genus ''Ferocactus ''Ferocactus'' is a genus of large barrel- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kadenicarpus
''Kadenicarpus'' is a genus of flowering plants belonging to the family Cactaceae. It is native to eastern Mexico. It has been synonymized with ''Turbinicarpus'' but molecular phylogenetic studies have supported its monophyly and separation from that genus. Taxonomy The genus ''Kadenicarpus'' was first proposed by Alexander Doweld in 1998. The name is in honour of Nikolai Nikolayevich Kaden (1914–1976), a Russian botanist. Most subsequent treatments rejected ''Kadenicarpus'', sinking it 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 ''Kadenicarpus'' was sister to a clade of ''Ariocarpus'' and a more narrowly circumscribed and so monophyletic ''Turbinicarpus'': Species , Plants ...

Glandulicactus
''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 ...

Ferocactus
''Ferocactus'' is a genus of large barrel-shaped cacti, mostly with large spines and small flowers. There are about 30 species included in the genus. They are found in the southwestern United States and northwestern Mexico. Description The young specimens are columnar but as they grow older ribs form and they take on a barrel form. Most of the species are solitary but some, such as ''Ferocactus robustus'' and '' F. glaucescens'', have clustering habits. The flowers are pink, yellow, red or purple depending on the species, and the petals sometimes have a stripe of a darker colour. Habitat They are desert dwellers and can cope with some frost and intense heat. The typical habitat is hot and very arid, and the plants have adapted to exploit water movement to concentrate their biomass in areas where water is likely to be present. Like ''Sclerocactus'', ''Ferocactus'' typically grow in areas where water flows irregularly or depressions where water can accumulate for short periods ...

Escobaria
''Escobaria'', pincushion cactus or foxtail cactus is a genus of low-growing cacti that range from the southernmost parts of central and western Canada through northern Mexico, with one species in Cuba. The genus comprises about 23 species. The term "pincushion cactus" may also refer to the related ''Mammillaria''. The stems of ''Escobaria'' range from globose to cylindrical, and lack nectar-secreting glands; while ribs are absent, tubercles are present, tending to become corky and deciduous as they age. The flowers usually appear in spring and may have a variety of colors, while the fruits are almost always red. The seeds in this genus are notable for being deeply pitted. Common species include the Missouri foxtail cactus '' E. missouriensis'', widespread in grassland and forest west of the Mississippi, and the spinystar '' E. vivipara'', [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epithelantha
''Epithelantha'' (button cactus) is a genus of cactus that is native to north-eastern Mexico, and the south-western United States from western Texas to Arizona. There are eight species recognised in the genus ''Epithelantha''. The name ''Epithelantha'' refers to the flower position near the apex of the tubercles. Description ''Epithelantha'' are very small cacti with globe-shaped or cylindrical stems typically up to one inch in diameter, rarely reaching two inches long. Tiny whitish spines completely cover the surface of the stem. The flowers are also tiny, growing from the tip of the stem. Fruits are bright red. The fruit of all species is said to be edible.

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.
