were caused by this fungus. Of course the fruit of this orna- 
mental plant is of no economic importance. 
ROSE, Rosa sp. 
Crown Gat, Bacterium tumefaciens Sm. & Towns. Plate 
XIX b. We have reported previously this bacterial disease on 
the following hosts: apple, bittersweet (Japanese), blackberry, 
peach, plum, and raspberry. Besides these, we have reported 
a somewhat similar trouble on the branches of oak trees, and a 
trouble of grapes which we have considered a winter injury, 
but which some others attribute to the crown gall organism. 
While the rose has been reported elsewhere as a host, it had not 
been found infected in Connecticut until Walden, in December, 
1911, while inspecting Manetti stock recently imported from Eng- 
land by A. N. Pierson of Cromwell, discovered a few plants 
showing the galls conspicuously on the roots. Specimens of 
these have been planted in our greenhouse for over a year, and 
the disease does not seem to have as yet very seriously affected 
the plants, or to have spread to any extent to the new roots. 
TURNIP, SWEDE, Brassica campestris. 
PuHoma Rot, Phoma Napobrassice Rost. Plate XXc-d. In 
December, 1912, Mr. W. N. Durgy of Danbury noticed a rot 
trouble in his Swede turnips, and later sent specimens to the Sta- 
tion for information. Concerning this he wrote: “As I have 
a trouble with my Rock turnips this year that I never had before, 
I thought I would send you a sample. They were nice and solid 
when I put them in the cellar, and now nearly half of them are 
like the sample. Will you kindly report what is the cause of 
the trouble.” Later, in answer to inquiries, he furnished the fol- 
lowing information: “The turnips did not show any spots when 
they were dug. The only thing we saw when we dug them was 
a decay on a very few around the top, so that when we pulled 
them, the top would come off, but I thought nothing of this. 
_I have not heard of any similar trouble around here. I have 
made a specialty of raising turnips for a good many years, and 
have always stored them in the same place, i. e., the cellar bottom. 
My cellar is warm, but not very damp. I have had the farm 
for sixteen years, and never raised but one crop of turnips
