Agalinis auriculata
Agalinis flexicaulis
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.

Agalinis flexicaulis is of conservation concern because of its limited distribution. The species is currently known from Bradford County.
Plants of Agalinis flexicaulis are distinguished by their weakly ascending main branches, which become more drooping and lax as they mature. It is most easily confused with the more widespread A. obtusifolia and A. tenella. Agalinis flexicaulis is differentiated from these species by characters in the key.
