is morphologically very similar to S. glaucus and
has been frequently treated within S.
glaucous, but the two populations are
geographically separated and Phylogenetic analyses of chloroplast DNA
are ambiguous regarding the closest relative of S. wetlandicus.
However, this species is related to S.
brevispinus, S. glaucus, S. wrightiae,
S. whipplei, and S. parviflorus. We refer to
this species as the Sclerocactus glaucus complex.
