Flowers: calyx 5–7 mm, densely pubescent, hairs mostly relatively long; corolla 5–15 mm diam. Berries 8–10 mm diam. 2n = 24.
Phenology: Flowering Mar–Oct (mostly late spring–early summer, depending on rain).
Habitat: Deserts, dry grasslands, frequently on roadsides or dry desert washes.
Elevation: 500–900 m.

Discussion
Chamaesaracha crenata occurs primarily in the Big Bend region of Texas and adjacent Coahuila, Mexico. Plants are robust, forming dense mounds. J. Henrickson (2009) included C. crenata within C. villosa. The two species are very similar; populations in and around Big Bend National Park compare more closely to the type of C. crenata.
Selected References
