Discussion

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.
