Mammillaria parkinsonii, also known as owl-eye pincushion or owl-eye cactus, is a species of flowering plant in the Cactaceae family.
 It is endemic to Queretaro, Mexico.
 Mammillaria parkinsonii is listed as Endangered due to a limited distribution (extent of occurrence ca 2,500 km2), severe fragmentation, a continuing decline due to illegal collection, and degradation of its habitat across its range.
 Clarification of the taxonomic status of this species is a research priority.
Macleaya or plume poppies is a genus of two or three species of flowering plants in the poppy family Papaveraceae, native to China and Japan.
 They have frilly leaves of olive green or grey colour, 25 cm long, and tall stems with airy plumes of petal-less, tubular, off-white or cream flowers.
The genus Mammillaria is one of the largest in the cactus family (Cactaceae), with currently 200 known species and varieties recognized.
 Most of the mammillarias are native to Mexico, but some come from the southwest United States, the Caribbean, Colombia, Venezuela, Guatemala and Honduras.
 The common name "pincushion cactus" refers to this and the closely related genus "Escobaria".
Mammillaria painteri is a species of plant in the Cactaceae family.
 It is endemic to Mexico.
 It is usually found near, but not limited to, San Juan del Rio, Guanajuato.
 It is commonly referred to as the biznaguita in Spanish.
 It is also known by many to be synonymous with "Mammillaria crinita" subspecies "crinita".
 It was evaluated and added to the IUCN Redlist in 2002 as data deficient.
 The causes of this species' endangerment or threats to its well-being are not clear.
Mammillaria mammilllaris, common name Woolly Nipple Cactus, is a species of plant in the Cactaceae family.
 It is the type species of the genus "Mammillaria".
 It has been described by Carolus Linnaeus as "Cactus mammillaris" in 1753.
 The specific epithet "mammillaris" comes from the Latin "mammilla", meaning "nipple", with reference to the characteristic tubercles.
Mammillaria dioica, also called the strawberry cactus, California fishhook cactus, strawberry pincusion or fishhook cactus, is a cactus species of the genus "Mammillaria".
 Its common name in Spanish is "biznaga llavina".
Mammillaria multidigitata is a species of flowering plant in the Cactaceae family that is endemic to San Pedro Nolasco Island in Mexico, growing on steep slopes.
 "Mammillaria multidigitata" sprouts a white to cream-colored flower from spring to early summer.
Mammillaria microthele is a species of plant in the Cactaceae family.
 It is endemic to Mexico.
 Its natural habitat is hot deserts.
 It is threatened by habitat loss.
 This species is sometimes considered a subspecies of "Mammillaria formosa".
Mammillaria rhodantha (common name rainbow pincushion) is a plant in the cactus family (Cactaceae) and is one of 171 species in the genus "Mammillaria" which are characterized by having nipple-shaped tubercles or prominences on their surface.
Mammillaria fraileana is one of about 200 species of the genus "Mammillaria" from the cactus family Cactaceae.
 This species is native to Mexico and can be found along the east coast of the southern part of Baja California Peninsula in Desert Scrub communities.
 They tend to grow in non calcareous dry granite-based soil but can also grow in rocky habitats, either in rock fissures or directly on top of the rock surface even without the presence of soil.
 Thus, the mineral composition of the rocks in their habitat directly influence their abundance.
 The habitat of "Mammillaria fraileana" is home to succulent flora and is particularly rich in local endemics.
 Currently, no major threats to the species are known to exist.
