The stamens and pistil are more or less aborted and mal- formed and no fruit is produced. Plate I, figure 1, shows normal flowers for comparison. All intermediate gradations of phyllody can usually be found among diseased vines, from the simple form, in which there is only a shortening and thickening of the parts of the perianth, to cases in which the entire flower is replaced by a short branch with small leaves, as shown in Plate II, figure 1, c, d, and Fig. 1.—A cranberry plant in which the terminal bud has developed into a ninner instead of a fruiting bud. Plate III shows a condition in which the different floral organs are represented by whorls of green, leaflike structures on the prolonged axes. Besides the transformation of the floral organs, other abnor- mahties of growth are usually found. Plate IV shows details of a malformed flower and various conditions of development of leaflike bodies in whorls on the prolonged floral axis. Affected plants have a great tendency to develop lateral branches from the usually latent axiUary buds situated on the vine below the fruit bud, as shown in flgure 1. The branches are slender and weak and fail to produce normal flowers or fruit. They give the plant a kind of witches'-broom appearance. In some instances the end of the flowering shoot, in- stead of forming a fruit bud for the next season, as is the case in.
