In the open grassland of Boulder Park the genera represented 

 by the greatest number of plants, not of species, are Poa, Festuca, 

 Koeleria and Muklenbergia, while in the forests there are other species 

 of Poa and Festuca together with representatives of Bromus and 

 Calamagrostis making up a large part of the grass-flora. In moist 

 situations along streams or near lakes perhaps the most abundant 

 grasses belong to Agrostis, Calamagrostis, Desckampsia, Alopecurus, 

 and Panicularia. 



The senior author has in preparation a paper which will deal with 

 the ecology of the dry grassland of Tolland and adjacent districts 

 and in this a full discussion of the abundance of the different grasses 

 will be given.
