Cactoideae

species of plant in the family Cactaceae

Copiapoa is a genus of flowering plants in the cactus family Cactaceae, from the dry coastal deserts, particularly the Atacama Desert, of northern Chile.

The genus Aztekium contains two species of small globular cactus. Discovered in 1929 by F. Ritter, in Rayones, Nuevo León, Mexico, this genus was thought to be monotypic (with Aztekium ritteri) until a second species (Aztekium hintonii) was discovered by George S. Hinton, in Galeana, Nuevo León in 1991. A further possible species, Aztekium valdezii, was described in 2011, but is considered to be a synonym of A. ritteri.

The Cactoideae are the largest subfamily of the cactus family, Cactaceae, and are widely distributed throughout the Americas. Cactaceae is the 5th most endangered plant or animal family evaluated globally by the International Union for Conservation of Nature. Around 80% of cactus species belong to this subfamily. The genera of the Cactoideae are characterized by microscopic foliage leaves. All photosynthesis occurs in shoot cortex cells covered by a persistent epidermis and stomata. Another important characteristic of this subfamily is ribbed stems, which enable the inner cortex to expand radi

Leptocereus is a genus of cacti that are native to the Greater Antilles. It has been placed in the tribe Leptocereeae or in a broadly defined Echinocereeae.

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.

Acharagma is a genus of cactus from northern Mexico, comprising three species.

Austrocactus is a genus of cacti with ten species endemic of southern South America, in Argentina and Chile.

Neoraimondia is a genus of medium to large cacti from Peru. The genus is named after the Italian-born Peruvian explorer, naturalist, and scientist, Antonio Raimondi. ==Description== The plants of the genus Neoraimondia are shrubby to tree-like, candelabra-like columnar cactus are branched from the base and reach a height of up to 15 meters. The upright, usually gray-green stems reach a diameter of up to 40 centimeters. Their 4 to 8 ribs are widely spaced. The large, round to elongated areoles are cone-like short shoots. These short shoots, viewed as condensed inflorescences, are among the lon

Neolloydia is a genus of cacti. ==Description== These small, low-growing cacti are usually solitary or form loose cushions. They have spherical to cylindrical shoots that are typically yellowish-green with whitish, woolly tips. The plants measure 3 to 6 centimeters in diameter and 5 to 24 centimeters in height. They have weakly developed or absent ribs. Distinctive conical warts, 3 to 10 millimeters long and 6 to 10 millimeters wide, are prominent on the surface. The areoles are dimorphic, about 3 to 5 millimeters in diameter, spaced 8 to 12 millimeters apart, with a furrow. Central spines, w

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. The main threats to cactus species are poaching, farming, mining developments, and climate change.

Echinomastus (meaning "spiny breast") was a formerly recognized genus of cacti. , it is accepted as a synonym of Sclerocactus. Species formerly placed in the genus are native to the southwestern United States and Mexico. thumb|Sclerocactus johnsonii, formerly Echinomastus johnsonii

Yavia cryptocarpa is a species of cactus (family Cactaceae) and the only species of the newly discovered genus Yavia. The genus is named after Argentina's department Yavi, Jujuy Province, where the plant is endemic to sparsely vegetated rocky slopes. The plant is also sometimes put in the tribe Notocacteae. The specific epithet cryptocarpa refers to the plant being a cryptocarp. This means that the fruits are formed inside the plant's body, thus being only visible when the plant shrinks in the drought period. ==Description== The species, with very tuberous roots, has a subglobular stem, has a

Calymmanthium is a monotypic genus of primitive tree-like cacti from northern Peru. The only species is Calymmanthium substerile (also known as C. fertile). It belongs to the tribe Lymanbensonieae. The young flowers of Calymmanthium are completely encased within the plant's pedicel until it is fully developed, at which time the growing yellow flower swells until it cracks the pedicel open, allowing pollinators access. The plant has an upright trunk, but many of the branches sprawl on the ground.
