locality, along South Avenue, I found this summer another plant 

 of this fern several rods away from the first clump found in 1903. 

 This shows that a plant may be easily overlooked in a certain 

 locality, for I have visited this place more often than any other of 

 my fern haunts, each time in the hope of discovering another 

 plant of the fern. It shows also that the fern may be present in 

 other places on Staten Island besides the five stations mentioned, 

 even though it has not been found. 



Near Suffern, Rockland County, N. Y., I visited a swamp in 

 company with Mr. Wm. T. Davis, July 23, 1905, and after a short 

 search I found one plant of the fern near one end of the swamp. 

 Near the other end of the swamp there were a number of plants 

 of this fern growing with several plants of D. cristata x nmrginalis 

 and others. The latter portion of the swamp had been partially 

 cleared of timber. The main swamp had some large trees and 

 supported a rather luxurious vegetation, consisting largely of 

 ferns. The osmundas and the spinulose ferns were most abun- 

 dant, as is usual in such a swamp in this region. Then there 

 were the Clinton, Goldie, crested, marginal and other ferns. 



On September 3 of the same year Mr. S. C. Edwards took me 

 to a swamp near Lisle, Broome County, N. Y., where we spent 

 about an hour climbing about on fallen trees and mossy hum- 

 mocks over the boggy ground, and we found a colony of two or 

 three vigorous plants of D. Boottii among other interesting plants. 

 D. cristata and D. spimilosa were also present. 



In the vicinity of Mountain Lodge, Old Forge, N. Y., during 

 the time of the Symposium this year, I found Boott's fern at four 

 different places, in each of which D. Boottii was found more 

 abundant than D. cristata. These were open grassy swamps near 

 the borders of lakes or else where the forest had been partly 

 cleared. Dryopteris spimilosa was also found in these open grassy 

 swamps ; but it was not found in the denser forest where the sub- 

 species intejnnedia abounded. 



The most luxuriant growth of Boott's fern that has come 

 under my observation is that of a swamp near Newfoundland, N. 

 J., which Mr. Davis and I partially explored on July 28 of this 

 year, and which I visited again on September 3. We found the
