Solidago faucibus

Gorge Goldenrod

Solidago faucibus Wieboldt is a large headed species that has a strong preference for gorge-like areas where rivers and creeks are entrenched in the surrounding terrain. It occurs in much more mesic sites than other taxa in the S. arguta complex.  The phyllaries are sometimes striate and the species is a decaploid with 2n=90 (Semple & Cook 2006 FNA).  The species was included in a multivariate study of S. sect. Argutae and was strongly supported as distinct from other species in the S. arguta complex. Semple and Morton (2024) presented a map of the cytogeography of S. faucibus.
