[1] The species was first described by Sabin Berthelot and Philip Barker-Webb in 1840, published in Natural History of the Canary Islands.

[2][3] Aichryson santamariensis was previously included in this species, but is now (since November 2015) considered a different species endemic to Santa Maria Island, Azores.
