Discussion

Agalinis auriculata is rare throughout its relatively broad range and has been the focus of recent field studies. It is probably extirpated in the District of Columbia, Michigan, New Jersey, Texas, and West Virginia; it was rediscovered in Pickens County, Alabama, in 2007 and Lewis County, Kentucky in 1998. The species is considered critically imperiled in at least 11 states and imperiled in another five and is the species is most abundant in Illinois, eastern Iowa, and northern Missouri.

Agalinis auriculata is in the Center for Plant Conservation’s National Collection of Endangered Plants.
