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 villosa occurs within 30–40 miles of the Rio Grande River in Trans-Pecos Texas and adjacent Mexico. It is robust and villous, with branching stems forming mounds 1 m across; it is most similar to C. crenata, with which it is easily confused. The principal characters to distinguish the two species are leaf shape and vestiture. The similarities and differences were discussed by J. E. Averett (2010).
