Additional Information at NatureServe

Diagnostic Characteristics:
This Phacelia differs from other common species in having 1) the stamens included (not exerted) in the corolla; 2) the anthers are not villous (long hairy) and 3) the stems are generally decumbent, that is, weakly laying across the ground rather than erect. It is primarily found in western Kentucky.

Management:
Extensive tree removal in the habitat for this species would likely be detrimental due to changes soil moisture and light conditions.

Global Range:
Midwestern endemic; found in the Ohio- Mississippi R. junction in Illinois, Kentucky, Tennessee, Arkansas, and Missouri. Wabash R. in Indiana and Illinois. Reports from Eastern states (Maryland, Virginia, and North Carolina) as well as D.C. are now referred to a different species, Phacelia covillei, but are considered to be P. ranunculacea in many references.
