Key to species of Sedum section Gormania in western North America

The key below was based on living material. It relied on characters that were difficult to observe on pressed dried material in a herbarium, such as inflorescence wax, flower colors, petal shape and angle, stem leaf attachment, and the density of sterile rosettes growing in sunny exposed situations. We suggest keying plants that retain some stem leaves, early in the flowering cycle.
