. Figure 3, Salsify yellows. One healthy plant and two diseased, from Hagerstown, Md., Sept. 19, 1929. Determination verified by L, 0. Kunkel. Note dwarfing effect of disease and development of many yellowed, filamentous leaves on affected plants. (Withering of tips of both diseased and healthy plants is due to the fact that plants were held several days before being photographed.). Photo by Fobert, Sept. 28, 1929.
