A new species of stonecrop (Sedum section Gormania, Crassulaceae) from northern California

Abstract

Sedum citrinum is described as a narrow endemic from three populations on ultramafic bedrock in the Klamath Mountains of southern Del Norte County, California, in the United States. It is distinguished from Sedum obtusatum subsp. boreale by its flattened inflorescence with elongate lower branches, as well as its deep yellow flowers and yellow anthers. © 2014 Magnolia Press.
