Whetzel) The common white "rust" of cruciferous plants appears to be common throughout the world. The fungus is frequently one of the first of the order to make its appearance in the spring and the last to disappear in winter. Evidently, it is not readily affected by minor climatic differences, and probably slight dews are sufficient to insure its propagation. This fungus is most common upon the forms of the ubiqui- tous shepherd's purse (Capsella Bursa-pastoris); but it is also common upon the radish (Raphanus sativus), horse radish (Cochlearia Armoracia), cress (Brassica oleracea), turnip (Bras- sica Rapa), mustard {Brassica nigra), water cress (Radicula Nas- turtium-aquaticum), Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Duggar, Benjamin M.
