like structure. These vary more or less but are seldom larger than 

 represented in the plate, which shows three of the different forms 

 noticed. The two petal-like lobes at the apex of each style-branch 

 are in / Hookcri usually spreading rather than slightly overlapping 

 as was noticed to be the case in specimens of /. versicolor observed 

 at Cutler. 



The fruit of /. Hookcri, which matures fully two weeks earlier than 

 that of /. versicolor, is broader, shorter, and thinner-walled. It is 

 always beakless and is sometimes rather bluntly triangular while at 

 others, especially when young, it is inclined to be sharply angled. 



The plants grow in great abundance on the farm of Mr. W. R. 

 Corbett of Cutler, who told us that since Dr. Kennedy called his 

 attention to the two species last year he had been watching them 

 and now had no difficulty in telling them apart, even in the dark, by 

 simply feeling of the pods. It is not easy to imagine a more beauti- 

 ful sight than that formed by thousands of these plants growing as 

 they do along the summits of the cliffs, often making blue areas 

 which can be seen for a long distance.

NOTES ON VERMONT MOSSES. 

 A. J. Grout. 



Since the publication of the supplement to my Vermont Mosses I 

 have spent two summers in the state and have collected copiously 

 each season. 



I have found several species not before reported from the state 

 and have also been able to verify several of Frost's doubtful reports 

 so that it seems probable that his list is entirely reliable. 



The collections from Newfane have been of special interest to me 

 as they are mostly from places familiar to me from childhood and 

 over which I had passed times without number.
