FALSE BLOSSOM OF THE CULTIVATED CRANBERRY. 3 
normal plants, continues to grow and produces a long, slender run- 
ner, as shown in 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. 
ORIGIN 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 writer 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 FlG 2 _ A cranberry plant to which the nor .

been obtained from Wisconsin. In the fifth case the variety was 
unknown, but this also had come from Wisconsin. These 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 the plants were of the Jumbo variety obtained 
from Wisconsin and planted several years previously. 1 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 whether these diseased vines are really eastern plants or have 
arisen from Wisconsin cuttings is very difficult to determine, since 
plants affected with false blossom rarely develop normal fruit. This 
has raised the question of the possible infectious nature of the disease. 
1 Since this was written the disease has been found in other bogs in New Jersey under such conditions 
as to suggest that the disease may have developed there independently.
