Florida. Mr. Harper reports it also from the sand hills of North 
Carolina. I have seen no specimens from Virginia. 
Pinus PALUSTRIS Mill. is another very rare tree in our region. It 
has been reported from the Dismal Swamp, but I have not seen any 
specimens of it from that place. Mr: Harper (l. c.) reports it common 
on the coastal plain of North Carolina, “especially on the sandhills.” 
Picea. Too little botanizing has been done in our mountains to 
give us any adequate notion of the distribution of our spruces. The 
same is true of our firs and the tamarack. The latter was not known 
from Maryland at the time I prepared the booklet on the Conifers. 
T'suGA CANADENSIS L. The hemlock is frequent throughout the 
mountains of Maryland and Virginia. I have observed it in many 
places: in West Virginia it is quite common. Solitary trees are to be 
found along the Potomac River within 15 miles of Washington. So 
fas as I know we have only one published record of this tree from the 
coastal plain: it is mentioned in the Plant Life of Maryland by Mr. 
Shreve,” who records it from Watts Creek, Caroline County, some three 
miles south of Denton. While on a botanical trip to the Eastern 
Shore, September 23, 1912, Mr. Stevens of Queen Anne, Md., took me 
to a colony of what the inhabitants called the “ yew-pine," some three 
or four miles south of that village, along the Tuckahoe River. I was 
astonished to find a large number of Tsuga canadensis lining both 
banks of the river. There was a considerable mixture of species, 
for many of the swamp species, as Nyssa, Liquidambar, and Quercus, 
were represented. The largest hemlocks were 3 dm. in diameter. 
There were also a large number of saplings, and Mr. Stevens estimated 
the number of hemlocks at 3000. The presence of a great number of 
robust saplings leads us to the belief that these trees are native and 
not by some agency or other introduced. 
Owing to lack of facilities for crossing we examined only the right 
bank of the river, so we have little knowledge of the conditions on 
the other bank, which, however, appeared still more favorable to the 
hemlock. The vernacular name is of some significance and leads us 
to believe that it could not have been applied to our tree except by a 
people who were familiar with the yew. So we must draw the conclu- 
sion that the first colonists gave it the name yew pine. Being familiar 
with the European tree and finding our tree with “yew-leaves” dif-
