REPORT OF THE STATE BOTANIST I9IO 7I 



The number of species of flowering plants and ferns found in 

 this marsh is 57. This is considerably less than the number found 

 in Cranberry marsh, though the area of the marsh is apparently 

 more than twice as large. On the other hand, but one visit was 

 made here and that so late in the season that probably some early 

 flowering herbaceous species were overlooked. 



A list of the names of the species found in each marsh is given 

 below. It will be seen that 33 species are common to both marshes. 

 This is more than half the number of species found in Averyville 

 marsh. These are species likely to be found in most of our larger 

 cold sphagnum bogs and marshes. They are the active agents in 

 the formation of peat beds and in preparing the marsh for the 

 habitation of the larger shrubs and trees. In other words, they 

 are the forerunners of swamps, the trees and shrubs of which, in 

 turn, prepare the way for productive lowland meadows and truck 

 gardens. Of the 33 species common to the two marshes 15, or 

 nearly half, are trees or shrubs. This indicates an advanced stage 

 of the marshes toward a wooded swamp. In Bonaparte swamp the 

 number of trees and shrubs is 29, in Cranberry marsh 20, in Avery- 

 ville marsh 21. The number of species common to the three marshes 

 is 19. In the following list of species will be found the names of 

 the species of each of the two marshes and those common to the 

 three marshes.
