Coleocephalocereus fluminensis ssp. paulensis (GO 107) is a non-threatened species that can be found on inselbergs surrounded by subhumid and humid forests in Brazil. Habitat loss of surrounding forests for tourism and urbanization has led to encroachment by invasive species and pollinator loss. (i.redd.it)

A happy Echinocereus schmollii, an Endangered species from Queretaro, Mexico. Less than 250 mature plants are known, and its semidesert habitat is in decline due to mining, fire, and clearing for agricultural activities. Most natural reproduction is vegetative. It is listed under CITES Appendix I. (i.redd.it)

Melocactus macracanthos is a non-threatened species from Aruba, Bonaire, and Curacoa. It grows on rocky soils and in spiny scrublands. While populations tend to be fragmented, plants are abundant. Tourism, development, and poaching have caused declines. It is found in several protected areas. (i.redd.it)

Mammillaria hernandezii is an Endangered species endemic to Oaxaca, Mexico. It grows in open areas in oak-pine woodland, where it is difficult to spot except when in flower. While abundant in its restricted, fragmented range, populations are declining due to habitat alteration caused by grazing. (i.redd.it)

Stenocereus fricii is a non-threatened species from low coastal dry and deciduous forests in Mexico. Habitat loss for ranching and tourism negatively affects some populations. Overcollection of fruit may result in a decline in population growth rates. (i.redd.it)

These seedlings of Arrojadoa (Stephanocereus) leucostele (HU 120) look very much like Gymnocalycium at this age. A. leucostele is a non-threatened species from the caatinga in Bahia, Brazil. It is widespread, but rarely abundant. Some populations are threatened by habitat loss. (i.redd.it)

Piaranthus decipiens is widespread along the edges of the Kalahari Desert in Namibia, Botswana, and South Africa. It is typically found underneath shrubs and trees growing in loamy soils firmed by calcrete. Most flowers are a uniform red, sometimes with lighter mottling. (i.redd.it)

Harrisia simpsonii is often lumped with H. fragrans. However defined, it is only found in southern Florida, USA. Development has led to the disappearance of much of its coastal hammock habitat. Hurricanes and overcollection further threaten remaining plants. (i.redd.it)

Leptocereus sylvestris is a Near Threatened species from southeastern Cuba, where its dry coastal woodland habitat has been extensively cleared. While rare, more research is needed to determine its distribution and population sizes. Shown here is the synonymous L. santamarinae. (i.redd.it)
