distribution, and if it serves as a host plant for the fungus of 
snapdragon anthracnose the problem of controlling the latter 
disease is a more complicated matter than has been supposed. 
Accordingly we made a thorough examination of the disease 
and the fungus causing it. The majority of the spots were black 
with the acervuli of a Colletotrichwn. Sets and spores vere 
abundant. The leaves on the diseased portion of the stem were 
nearly all dead and brown. Close examination revealed the 
presence of anthracnose spots on the dead leaves and there were 
also a few spots on the living leaves, but the leaf spots were in- 
conspicuous and not abundant. In all morphological characters 
the fungus agrees fully with Colletotrichum antirrhini and there 
is little doubt but it is that fungus. However, positive proof 
depends on cross inoculations with pure cultures. These have 
not been made. 
It was found that many small plants had been killed outright 
by the disease, but that there were also many others which, 
although their stems were covered with the spots, were, never- 
theless, flowering and apparently thriving. While the disease 
evidently does some damage to the wood, it seems unlikely that 
it can be turned to any practical account as an aid in its eradica- 
tion. 
The original place of discovery was near Milton on a steep 
hillside in a rather dry situation where the plants were partially 
shaded by peach trees. Later it was found in similar situations 
on two other farms at Milton and also at Middle Hope. 
IV. IMPERFECT FERTILIZATION AND THE LITTLE 
PEACH DISEASE. 
During the past few years peach growers in Michigan and 
in Western New York have been much concerned over the ap- 
pearance of a new and destructive disease known as the “ little 
peach” disease. It appears to have been first described by Taft? 
in March, 1898. In October of the same year a more extensive
