Agalinis auriculata
Agalinis fasciculata
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.

Although uncommon in the northern and northwestern portions of its range, Agalinis fasciculata is the most common and weedy species of the genus in the southeast, and also the largest in North America (especially in peninsular Florida around the strands), with a massive root system and stems with basal diameters to 25 mm. Plants in southern Florida flower intermittently year-round. It is one of the more variable species of the genus in the flora area in size of stems and leaves, and overall indument. See discussion under 28. A. purpurea for characters differentiating it and A. fasciculata.
