REPORT OF THE DIRECTOR TQIG 



35 



lake, Rensselaer county, and in Averyville marsh, North Elba, 

 Essex county, has been made. Two visits were made to the Cran- 

 berry marsh, one in July and one in September. A few plants were 

 found on the second visit that were not seen on the first, presum- 

 ably because they had not yet developed sufficiently to attract atten- 

 tion. The whole number of species found in this marsh is 72. 



One visit was made to Averyville marsh. It was in September, 

 and though the marsh covers a larger area than the Cranberry 

 marsh, only 58 species were found there. This is probably due in 

 part, at least, to the lateness of the visit. The number of species 

 common to the two marshes is 33. More than half the number of 

 species found in Averyville marsh occur also in Cranberry marsh. 

 Of the species common to the two marshes, 15, or nearly half, are 

 trees and shrubs. If we compare the list of species in Bonaparte 

 swamp with those of the two marshes we find only 19 species 

 common to the three localities. The flora of the wooded swamp 

 is seen to be quite unlike that of the open marsh, as might be 

 expected.
