Transformations of Flowers of the Cranberry in Various Stages of Phyllody. 



Fig. 1. — Modifications of the transformation of flowers: a, The flower with green, abnormally shaped 

 sepals and petals; the axis prolonged, bearing two whorls of small, green, leaflike bodies, the upper 

 whorl with eight abnormal stamens, the lower also with stamens; 6, an enlarged view of o; c, the upper 

 whorl of b, dissected, showing the abnormal floral organs. Within the outer whorl of four short, broad 

 bodies, were four much malformed organs, showing the condition intermediate between an aborted 

 petal and a stamen. Within this whorl were eight abnormal stamens and at the center a partially opened 

 bud, with two small, partially developed leaflike organs. 



Fig. 2. — A shoot in which the flowers are still further transformed: a, All the parts of the flower except 

 the stamens are green and more or less leaflike; 6, an enlarged view of a, showing the condition of the 

 stamens; c, a stage in which the parts, instead of being arranged in whorls, are more or less alternate 

 or spiral; d, an enlarged view of c. There is no sign of stamens present in any of these groups of smaU, 

 green, leafl ike bodies in c, the stamens being apparently the last organ to disappear in the metamorphosis 

 of the flower.
