History and Distribution. Prior to the summer of 1913, the rust had been reported but from two western coast states, California and Oregon. In 1895 it was determined as a new species by Holway, an American botanist, and named Puccinia antlrrhini (Diet, and Holw.) However, within a month after the station was apprised of the presence of the rust in the region north of Chi- cago, four new areas of infection had been located within a radius of fifty miles from the point at which the dis- ease was first reported. Then, in September, 1914, the writer learned that snapdragons growing on a private estate in northern Ohio were suffering an attack of the disease. The report was substantiated by the receipt of a quantity of diseased material from that locality at the station. Later two new areas of infection were located, one about a mile from the infection just mentioned in Ohio and the other in the western part of central Indiana. From.
