'This State Cabinet or, as it is called, Massachusetts State Her- 
barium is not mentioned in Miss Day's article *'The Herbaria of New 
England,” published in Vol. 3 of Rnopona. Now that the resting 
place of the collection has been located it is probable that a more 
careful examination of it than I was able to make would be well worth 
while.

A NEW MARITIME POLYGONUM FROM NOVA SCOTIA. 
M. L. FERNALD. 
IN 1913 the writer pointed out! that the large-fruited glaucous 
Polygonum of the coastal sands of the eastern United States is P. 
glaucum Nutt., not P. maritimum L. for which it had long been mis- 
taken; and that about the Gulf of St. Lawrence these large-fruited 
strand species are represented by P. Ra Babington, which is also 
found on the Bras d'Or Lakes of Cape Breton. 
During the past July, finding it necessary to “kill time” for twelve 
hours between North Sydney and Pictou, Nova Scotia, Mr. St. John 
and the writer fortunately selected Grand Narrows on Bras d'Or Lake 
as a desirable place to investigate. "There, on the gravel beach, P. 
Ha was abundant, as we had expected; but the chief surprise of our 
day was another large-fruited species growing with it in the gravels 
and quickly distinguishable as far as it could be seen by its color, the 
leaf-outline and the comparatively inconspicuous perianths, in which 
it strongly contrasted with the very glaucous and conspicuous P. 
Rav. The peculiar plant proves to be unique in the group to which it 
belongs, presenting characters which ally it to P. Rai on the one hand 
and to P. Fowleri Robinson on the other but which clearly separate 
it from each. It is here proposed as
