Flowers are lavender to rose-purple, bilaterally symetric, pikose externally, usually 1.6-2.5 cm long including flower tube and the five spreading to reflexed lobes.

Distribution & Occurrence
In full sun on the shallow soil of the easternmost outcrop of the Oakville Formation (a Miocene sandstone with large amounts of shell fragments). Canne-Hilliker and Dubrule (1993) describe the outcrop as a distinct island surrounded by a sea of Post Oak Savannah, Blackland Prairie, and farmland of a river valley. The Tyler County site is on the Catahoula barrens in pine savanna.
