normal plants, continues to grow and produces a long, slender run- 

 ner, as shown lq figure 2. Cranberry plants in bogs where this malfor- 

 mation occurs generally show an excessive vegetative growth, usually 

 forming a deep, dense mass of vines. 



In their dormant condition the ter- 

 minal buds are frequently enlarged and 

 abnormal and die during the winter. 

 Under some conditions the plants 

 produce few runners. 



ORIGm AND DISTRIBUTION. 



All the data at hand seem to indicate 

 that this disease first appeared in Wis- 

 consin. Cases of phyllody have been 

 found in Massachusetts, New Jersey, 

 Oregon, and Washington, but most 

 cases appear to be traceable to vines 

 obtained from Wisconsin. No printed 

 reference to this disease has been found 

 by the "svriter previous to his brief men- 

 tion of it (9) in 1908. The disease has, 

 however, undoubtedly been present in 

 Wisconsin for many years. 



The first cases of the disease dis- 

 covered in Massachusetts were exam- 

 ined by Dr. H. J. Franklin and the 

 writer in 1914 and have been reported 

 by Franklin (3). Affected vines were 



observed in five different bogs. ^ In f,«. 2.-A cranberry plant m which the Bor-

 been obtained from Wisconsin. In the fifth case the variety was 

 unknown, but this also had come from Wisconsin. Tliese vines had 

 been planted about 10 years previously. The next year, 1915, the 

 writer's attention was called to the occurrence of this disease in New 

 Jersey. In this case llio plants were of the Jumbo variety obtained 

 from Wisconsin and planted several years previously.^ In both Mas- 

 sachusetts and New Jersey a few scattered vines showing the disease 

 have been found in plantings of eastern varieties in the same bog, 

 but wlu^ther tlxiso diseased vines are really eastern plants or have 

 ari.sen from Wisconsin cuttings is very difficult to determine, since 

 plants affected with fals(! })lossom rarely d(vv<^lop normal fruit. This 

 has raised tlio (juestion of the possi])le infectious nature of the disease.
