About 1925 Mr. Walter Neff and Mrs. Ivy Neff discovered this species as a common weed in the Cedarville Cemetery and nearby pastures and roadside in Carroll County, about two or two and a half miles southwest of Burnettsville. Mrs. Neff has written of the discovery and described the plant (Amer. Bot. 36: 85-87. 1930). At that time the name was still in controversy. I visited this colony in 1929 and found that it formed an almost complete stand in a pasture of two to three acres and that it was scattered in pasture fields for a distance of about three miles. I sent specimens collected from this colony to Pennell who sent them to Murbeck for determination. Murbeck, in 1936, identified them as Verbascum phlomoides L. In 1937 I found this mullein common along an east and west road two miles north of Rochester, Fulton County and in several places along the Tippecanoe River south of Talma.
