The pine barrens in the fall-line sandhills of western Georgia can be accepted as the type locality for Ceranthera linearifolia as described by Stephen Elliott in his Sketch. This remote area between the Chattahoochee and Flint Rivers became accessible in the early 1800s with the building of the Federal Road from Washington, D.C. through Georgia to Mobile, Alabama. Subsequently renamed Dicerandra linearifolia by George Bentham, this new mint genus was among several plants found and described by Elliott along the Federal Road. To establish the type locality, new field collections from the Georgia pine barrens were compared with Elliott's collections sent to Hooker and Schweinitz. A specimen at Kew (k) is designated as the lectotype for C. linearifolia and a new isolectotype is found at Geneva (g). A suite of characters, including strikingly linear leaves with strongly revolute margins, two-flowered cymes and generally unbranched stems, was common to both the types and the new collections from the Georgia pine barrens.
