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] |
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". The species is listed in Appendix 1 of the Convention on International Trade in Endangered Species CITES (shorter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spine ...

Obregonia
''Obregonia'', the artichoke cactus, is a monotypic genus of cacti, containing the species ''Obregonia denegrii''. The species is endemic to the state of Tamaulipas in Mexico. The genus ''Obregonia'' is named after Álvaro Obregón, while the species is named after Ramon P. De Negri, who was the Minister of Agriculture of Mexico when the cacti was first described by Alfred Frec in 1923. Description This rare species resembles an inverted green pine cone with a woolly center. It grows slowly in culture and requires little water. It benefits from full sun and is multiplied by seed. It is very slow growing. It is an IUCN Red List Endangered species. Uses The Nahuatl Indians call the plant ''peyotl'', and it is said to have hallucinogenic alkaloids.

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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leuchtenbergia Principis
''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.

Digitostigma
''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 ...

Sclerocactus
''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 alon ...
