Discussion

Varieties 2 (2 in the flora).

The mature carpels of Sedum spathulifolium have five ribs and prominent lips along the adaxial suture. The flowers are sweetly fragrant.

Until recently, Sedum nuttallii was thought to have been published first in 1833 (not 1829), a year after S. nuttallianum Rafinesque; consequently the latter name has been applied incorrectly to this species.
