Aichryson is a genus of about 15 species of succulent, subtropical plants, mostly native to the Canary Islands, with a few in the Azores, Madeira and Morocco, and one in Portugal. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its The Saxifragales are an order of Dicotyledon Flowering plants In the APG II classification system it includes the following families The Crassulaceae, or orpine family, is a family of Dicotyledons They store water in their Succulent leaves Philip Barker Webb ( July 10, 1793, Milford House, Surrey - August 31, 1854) was an English Botanist Sabin Berthelot ( April 4, 1794  – November 10, 1880) was a French naturalist and Ethnologist. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic The Canary Islands ( English pronunciation kəˈnæriː ˈaɪləndz Spanish: Islas Canarias, ˈizlas kaˈnarjas are a Spanish The Azores ( Açores ɐˈsoɾɨʃ or) is a Portuguese Archipelago in the Atlantic Ocean, about 1500 km (950  mi) from History See also History of Madeira Pre-Portuguese times Pliny mentions certain Purple Islands the position of which with reference to the Morocco (المغرب "al-Maghrib" officially the Kingdom of Morocco (المملكة المغربية is a country located in North Africa Portugal, officially the Portuguese Republic (República Portuguesa is a country on the Iberian Peninsula.

The species of Aichryson are not frost-resistant. They are related to Sempervivum, Jovibarba, Greenovia, Aeonium and Monanthes, readily seen in their similar flowers. Houseleeks or Liveforever ( Sempervivum) are a Genus of about 40 Species of Succulent plants of the Crassulaceae family Jovibarba ("beard of Jove " is a small Genus of three species of Succulents in the family Crassulaceae, endemic Aeonium is a Genus of about 35 species of Succulent, subtropical Plants of the family Crassulaceae. Aeonium is a Genus of about 35 species of Succulent, subtropical Plants of the family Crassulaceae. Monanthes is a Genus of small Succulent, subtropical plants of the Crassulaceae family

Relationships

Recent phylogenentic studies of Crassulaceae indicate that Aichryson is closely related to Monanthes and Aeonium (both genera are also largely endemic to the Canary Islands). Monanthes is a Genus of small Succulent, subtropical plants of the Crassulaceae family Aeonium is a Genus of about 35 species of Succulent, subtropical Plants of the family Crassulaceae. Two other genera of Crassulaceae that have many-parted (polymerous) flowers (Sempervivum and Jovibarba) are not closely related to the three Canary Island genera. Houseleeks or Liveforever ( Sempervivum) are a Genus of about 40 Species of Succulent plants of the Crassulaceae family Jovibarba ("beard of Jove " is a small Genus of three species of Succulents in the family Crassulaceae, endemic [1][2][3][4]

On the Canary Islands, the center of species diversity seems to be the island of La Palma Relationships within Aichryson were investigated by Fairfield et al (2004) [Plant Systematics and Evolution248: 71-83]. They found that the five subspeies of A. pachycaulon were not each others closest relatives (monophyletic) and additional species may need to be erected after additional study.
