Discussion

Calopogon oklahomensis originally was thought to be restricted to the south-central states; it is much more widespread. It is, however, nearly extirpated outside the south-central states. DNA evidence, as well as its hexaploid chromosome number, suggest that this species may be an alloploid, possibly derived from ancient hybridization between C. barbatus and C. tuberosus (D. H. Goldman 2000).
