Ammoselinum butleri (Engelm. ex S. Watson) J.M. Coult. & Rose

Ammoselinum butleri (Engelm. ex S. Watson) J.M. Coult. & Rose. Ammoselinum butleria, commonly called the Butler's sandparsley, is a species of flowering plant in the carrot family (Apiaceae). It is native to North America, where it is found primarily in the South Central United States. It is most often found in disturbed sandy areas, including lawns. Its range has expanded eastward in recent times, leading some authorities to consider populations east of the Mississippi River to be non-native.
