REPORT OF THE BOTANIST. 69 
notwithstanding the presence of prickles on the cones. In these 
specimens the cones are one to one inch and a half in length, 
and the prickles are very short, weak and obscure, and on 
some of the scales are wanting. In the southern specimens the 
cones are two inches in length and the prickles are stout and 
very distinct on all the scales. The leaves in both are of the 
same length, but less dense in the southern specimens. 
It is possible that P. inops and also P. mitis, which Dr. 
Torrey reported, on the authority of Michaux, as occurring 
near Albany, may occur in the southern part of the State or on 
Long Island. At present we can claim positively only the four 
species, P. Strobus, P. rigida, P. resinosa and P. Banksiana. 
The last one is not known to me to occur anywhere in the State 
except in Essex county where it was first detected by Dr. G. 7. 
Stevens. 
The four New York species may be tabulated in such a way 
as to be easily identified by any one possessing a branch bear- 
ing either leaves or cones ; thus,

Lake Sanford, Essex county, with the normal form. The 
stem is much prolonged beyond the insertion of the peduncle 
which thus becomes lateral.
