Discussion
Nuttall reported Krameria lanceolata as occurring in Arkansas, and his account was repeated by Delzie Demaree and later workers. As reported by J. H. Peck (2003), the species is not known to occur in the state and the original claim presumably was based on a specimen collected in the Arkansas Territory at a locality that is now in Oklahoma.
