enumerate merely the common and distinctive members of the pond 
flora, together with such of the more rare plants as have come within 
his experience, and to set forth certain observations as to their behav- 
ior and distribution. Much more active collecting must be done on 
the Cape before we can feel sure that its flora is well known, and there 
are few regions so near Boston which offer to the field botanist such 
opportunities for interesting and valuable work. 
The writer wishes to express his thanks to those who have aided

SARGENT in his manual of the trees of North America (1905) gives 
Lehigh county, Pennsylvania, as the northern limit of this species in 
the Eastern United States and says of it: “occasionally planted as

Massachusetts"; and in the Sylva, vol. VIII, p. 177, calls it “one of 
the most beautiful of the American oaks, and a most distinct and 
desirable ornament of the parks and gardens of eastern America, 
where it is perfectly hardy as far north at least as the shores of Massa- 
chusetts Bay.” 
And yet it appears to be a rare tree in cultivation in this vicinity, 
two trees only being reported outside the Arnold Arboretum. One of 
these is near the entrance to the Chestnut Hill Reservoir, and the 
other close to Brush Hill Road in the town of Milton. 
Prof. Sargent informs me that he has had two plantings of this 
species in the Arboretum: one in 1873, and one in 1887, and both 
from Meehan of Philadelphia. The Reservoir tree is of the 1873 
planting and was sent with other oaks from the Arboretum to be set 
in the Boulevard adjacent to the Reservoir. There are several fine 
trees of the 1873 planting in the Arboretum; the best one is growing 
near the Motley house. This tree has a girth of 47 inches at three
