J. C. Arthur, New York Agric. Exper. Station, Geneva, N. Y., says: 'There is no record of the hollyhock disease caused by Puccinia Malvacearum occurring upon any cultivated plant in America, and is only reported upon wild plants in Kansas and California. The latter, moreover, may prove upon further observation to be distinct from the European species. It is a matter of interest, therefore, as to what fungus is referred to in the June number of the Monthly as being very destructive to hollyhocks; it is pretty certain that it is not Puccinia Malvacearum, as supposed. The writer will gladly examine and report upon any specimens sent him".
