Crategus gemimosa grows in rich forest glades and on the margins of woods usually in low 
moist rich soil, and is distributed from the neighborhood of Rochester, New York,’ and Toronto, 
Ontario, through Ontario” to the southern peninsula of Michigan,’ where it is very abundant as far 
north at least as the neighborhood of Saginaw,’ and where it probably grows to its largest size.° 
1 Crategus gemmosa was found in October, 1901, by Mr. John 
Dunbar in the Genesee Valley Park, Rochester. 
2 In Ontario Crategus gemmosa is common in the neighborhood 
of Toronto, where it was collected in May and October, 1901, by 
Mr. D. W. Beadle, and near London, where it was found by C. S. 
Sargent in September, 1901. 
8 The earliest specimen of this tree which I have seen was col- 
lected near Grand Rapids, Michigan, by Mr. C. W. Fallass in 
May, 1895.

5 The largest specimen of Crategus gemmosa which I have seen 
is growing at the southeast corner of Curtis and Forests streets in 
Grand Rapids, Michigan. This tree as measured by Miss Cole 
of that city in the autumn of 1901 is thirty feet high, with a 
trunk circumference two feet above the ground of thirty-four 
inches, and a spread of branches in one direction of twenty-five 
feet and seven inches, and of twenty-two feet in the other direc-
