found nearer than Bergen or Mendon. Among those found here, but 

 rarely or not at all in adjacent forests, may be noted : Clematis Vir- 

 giniana, Copiis trifolia, Drosera roiundifolia, Flozrkia proserpinacoides, 

 Rhus venenata, Saxifraga Pennsylvanica, Cornus Canadensis, Viburnum

 Ophioglossum vulgatu?n. 



Several other plants of the scarcer species occur near this station. 

 The walking fern, Cauplosorus rhizophyllus, is quite abundant at two 

 points within three or four miles. A square of twenty feet of the 

 chain fern, Woodwardia Virginica, was found here in 1894. No other 

 station for it except Mendon has been reported in the county. 

 Cassandra calyculata is very abundant two miles south-east of the 

 village. The eastern limit of the papaw, Asimina triloba, seems to be 

 within Monroe county. Several groups are growing in Parma, north 

 of Adams Basin, in Sweden, and thence westward. The trees spread 

 by root sprouts, forming dense groups from three to twenty feet high, 

 but all connected at the root. Seedlings seem to be scarce, although 

 the trees are usually well fruited. 



BERGEX SWAMP. 



Bergen swamp has long been considered one of the most inter- 

 esting botanical points in western New York. It lies in the north- 

 eastern part of the town of Bergen, Genesee county, between the West 

 Shore railroad and Black creek, about twenty miles from Rochester, 

 and is one of a succession of swamps which occupy a depression 

 extending from the Genesee river to the Niagara river. Through the 

 western part of this valley flows Tonawanda creek ; Black creek 

 drains the eastern portion. Bergen swamp lies upon the divide 

 between these two streams. 



This swamp consists of an open portion containing one hundred 

 or more acres, surrounded by a belt of woods from twenty to one 

 hundred rods in width. The open part is mainly a marl bed covered 

 with a variety of grass-like plants, chiefly sedges, with patches of 

 Sphagnum and a few dwarf cedars {Thuja) and tamaracks. The sur-
