or near the glaciated region of Pennsylvania. Here, associated often 
with Galium tinctorium (but perfectly distinct and showing little if 
any striking resemblance) and more rarely with G. Claytoni, was found 
in great abundance the object of our search. It was seen in two bogs, 
in the larger of which it at times formed a considerable portion of the 
low vegetation. 
Prof. Karl M. Wiegand very kindly examined material sent to the 
Gray Herbarium, and verified the identification. A full suite of 
specimens (showing diversity of habit assumed, depending upon the 
character of the associated vegetation) will be deposited in the Her- 
barium of the Academy of Natural Sciences of Philadelphia. Material 
of the original collection is also in the herbarium of Mr. Pretz at 
Allentown. 
Doubtless the plant will be found in similar bogs in the higher 
Alleghenies or in other localities on the Pocono Plateau, when these 
areas have been more systematically explored. There are bogs in 
Northampton County, south of the Blue Mountains (but within the 
terminal-moraine region), which are very similar in character to those 
on Aquashicola Creek and support many of the same species. These 
bogs have been pretty thoroughly explored but it would not be sur- 
prising if the Galium should be discovered there. Another very 
possible locality is the area of glaciated bogs in northern New Jersey. 
All of these areas, originally suggested to my mind by the occur- 
rence there of similar bogs and associated species, strikingly agree in 
general with the remark of Prof. Wiegand that Galium labradoricum 
in the Pocono of Pennsylvania would show a distribution like that of 
Amelanchier Bartramiana, which reaches its southern limit in the 
mountain regions of eastern Pennsylvania — in the Alleghenies, the 
Poconos, and the Blue Mountains. The general distribution of either 
of the two above species might be briefly written: Eastern Pennsyl- 
vania and the region around the western portion of Lake Superior 
northward to Labrador.
