Abstract
The Erysimum asperum-capitatum complex includes a vast array of taxa in the western U.S.A. and Mexico, most of these bearing specific or infraspecific names, and all to some extent intergrading in regions of allopatry. These appear to be best treated as belonging to but a single species, Erysimum asperum, with two subspecies: subsp. asperum, with but a single relatively well-marked var. asperum, this confined to the Great Plains Region of the central U.S.A., and subsp. capitatum of the higher, more western regions, the latter having an array of varietal names, the earliest being var. elatum, first proposed by Torrey in 1858. To accommodate the nomenclature of this overview, the following names are proposed: E. asperum subsp. capitatum (Douglas) B.L. Turner , comb. and stat. nov., and E. a. var. lompocense (Rossbach) B.L. Turner, comb. nov. consistently longer, linear, essentially entire leaves, and restriction to bare gypseous outcrops. Photographs of plants in the field, as well as the type, are provided, along with maps showing its distribution and that of its closest congener, O. capillifolia.Suggested Citation
