Monanthes is a genus of small, succulent, subtropical plants of the Crassulaceae family. The about ten species are mostly endemic to the Canary Islands and Savage Islands, with some found on Madeira. Its center of diversity is Tenerife, with seven species occurring on this island. On Fuerteventura and Lanzarote, only M. laxiflora occurs. Monanthes are not frost-resistant. They are linked with the genera Sempervivum, Greenovia, Aichryson and Aeonium, which is obvious from their similar flowers.
