On 16 July 1985, the authors discovered Lobelia appendiculata var. gattingeri growing in a small limestone glade in Warren County, Kentucky. The plants had already fruited and dried except for several new flowering stems that had bolted from the base of old flowering stalks. Identification of the specimens was confirmed by Drs. Jerry and Carol Baskin of the University of Kentucky and Dr. Robert Wilbur of Duke University.
