and slightly reddish or greenish in color, as shown in Plate I, figure 2, 
b and c. 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 e. 
p IG . l.— A cranberry plant in which the terminal bud has developed into a runner 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- 
malities 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 
axillary buds situated on the vine below the fruit bud, as shown in 
figure 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
