Cochemiea
''Cochemiea'' is a genus of cactus. The group was previously synonymized with '' Mammillaria'', until molecular phylogenetic studies determined that—when broadly circumscribed—''Mammillaria'' is not monophyletic; thus, ''Cochemiea'' has been accepted as a distinct genus. The Cactaceae family, as a whole, is the fifth most- endangered plant or animal family taxon, globally, as evaluated by the International Union for the Conservation of Nature (IUCN). The reasons for this are varied, ranging from climate change and habitat loss, in some regions, to the illegal harvesting ( poaching) of wild cacti for personal collections or sale on the black market, or blatantly sold, as-is, fresh from the wild. As these plants are naturally slow growers, wild cactus growth and reproduction rates may not meet the rate at which certain populations of species are being poached, thus creating gaps in the wild populations and risking complete regional depletion or extinction.

Cochemiea Macdougallii
''Cochemiea macdougallii'' is a species of cactus in the genus ''Cochemiea''. The plant has a greenish-gray epidermis and black spines. It is only known from Oaxaca, Mexico. Taxonomy The species was first described in 1961 by Edward Johnston Alexander Edward Johnston Alexander (July 31, 1901 – August 18, 1985) was an American botanist who discovered three species and one genus. He is the author or one of the authors of 205 entries in the International Plant Names Index. He was born in Ashevil ... as ''Ortegocactus macdougallii''. It was the only species in Alexander's genus ''Ortegocactus''. ''Ortegocactus'' was later synonymized with ''Cochemiea'', but a name in that genus was only provided in 2021.

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Cochemiea Barbata
''Cochemiea'' is a genus of cactus. It has previously been synonymized with '' Mammillaria'', but molecular phylogenetic studies have shown that when broadly circumscribed, ''Mammillaria'' is not monophyletic, and ''Cochemiea'' has been accepted as a separate genus. Taxonomy A 2021 molecular phylogenetic study of the "mammilloid clade", which included the genera ''Cochemiea'', ''Coryphantha'', ''Cumarinia'', ''Escobaria'', ''Mammillaria'', ''Neolloydia'' and ''Ortegocactus'', showed that it consisted of four monophyletic groups, which the authors re-circumscribed into four genera: ''Cumarinia''; '' Mammillaria'', with a reduced number of species; ''Coryphantha'', expanded to include species previously placed in ''Mammillaria'' and ''Escobaria''; and ''Cochemiea'', expanded to include a large number of species previously placed in ''Mammillaria'', as well as ''Neolloydia conoidea''.

Mammillaria Armillata (2)
''Mammillaria'' is one of the largest genera in the cactus family ( Cactaceae), with currently 200 known species and varieties recognized. Most of the mammillaria 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''. The first species was described by Carl Linnaeus as ''Cactus mammillaris'' in 1753, deriving its name from Latin ''mammilla'', " nipple", referring to the tubercles that are among the distinctive features of the genus. Numerous species are commonly known as globe cactus, nipple cactus, birthday cake cactus, fishhook cactus or pincushion cactus though such terms may also be used for related taxa, particularly '' Escobaria''. Description The distinctive feature of the genus is the possession of an areole split into two clearly separated parts, one occurring at the apex of the tubercle, t ...

Cochemiea Angelensis
''Cochemiea angelensis'' is a species of plant in the family Cactaceae. It is endemic to Mexico, and can be found close to sea level, partway down the Baja California Peninsula. Its shape is globose or short cylindrical, and grows up to 15 cm high. The flowers have two distinct color forms. The first is white, with pinkish midstripes on the outer petals; the second is much more deeply colored, with deep pink petals and maroon midstripe. These grow to 20 mm in length and 30 mm in diameter. References Mammillarias.netpage on ''M. angelensis''. Accessed 2 May 2009. angelensis Cacti of Mexico Endemic flora of Mexico {{Cactus-stub ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images.
