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 coniodes is highly variable in leaf shape, vestiture, and stature. It is similar to C. darcyi and C. coronopus. Some populations are similar to C. sordida. The variation and its significance were discussed by J. E. Averett (2010b). J. Henrickson (2009) recognized C. texensis, which has simple hairs and may also have an understory of glandular hairs, as distinct from the type of C. coniodes, which has only dendritic hairs; this is part of the variability across the range of the species.
