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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
