Sedum gypsicola is related to Sedum album and has been considered a synonym by some authors,[1] but it differs in having papillate leaves and a more restricted distribution.[2] Apart to the more widely distributed nominate subspecies (subsp. gypsicola), Sicilian plants have been described as an endemicsubspecies, subsp. trinacriae.[3]
