Discussion | 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.

Chamaesaracha edwardsiana occurs in the Edwards Plateau region of central Texas. J. E. Averett (1973) mapped a few populations in northern Mexico but most of those may belong with C. pallida. Chamaesaracha edwardsiana is most closely related to C. coronopus but differs in having broader, entire or nearly entire leaves. The species is similar also to C. pallida but lacks the relatively dense dendritic hairs on the leaves and has a generally more eastern distribution.
