swamps which are necessary for their existence. Some, however, 

 still survive, and we have fortunately pretty good lists of species 

 from others which have been destroyed. Probably the most 

 remarkable spot of this sort is Frazer's bog, near Willow Grove, 

 Montgomery County. 



Here we find quite a plantation of swamp magnolias, with 

 which grow a large number of coastal plain plants. From the 

 boyhood of the oldest residents and still earlier, according to- the 

 reports handed down by their fathers, this bog has presented 

 much the same condition as at present, but more recently strenu- 

 ous efforts have been made, with but little success, to fill it in 

 and convert it into a meadow. The flora of this bog was ap- 

 parently first collected by Mr. C. F. Saunders, later Mr. Alex. 

 MacElwee published some notes upon it,* and Mr. S. S. Van 

 Pelt and Bayard Long made collections. From these sources as 

 well as from my own herbarium the following list is compiled:
