Chamaesaracha sordida is known from western Texas, New Mexico, and Arizona. It is most closely related to C. coronopus and differs in having broader, mostly entire leaves. It is also similar to C. pallida; it lacks the relatively dense dendritic hairs on the leaves and has a generally more eastern distribution. Herbarium specimens from 2007 and 2008 indicate that it has been introduced into southern California (Clark Mountain Range, San Bernardino County) and may be naturalizing.
