Scikpus Smithii, Or. 



Shore of Cayuga lake, near Union Springs. Dudley. 



Oarex Steudelii, Kunth. 



Six-mile creek, near Ithaca. Dudley. 



Eragrostis Purshii, Schrad. 



Waste places about Albany. Clinton. This southern grass is 

 rapidly extending its range northward. Last year it was reported 

 from Yonkers, this year it appears to be well established at Al- 

 bany. It appears, like many other introduced plants, to follow 

 the lines of the railroads which are a powerful agency in extend- 

 ing the distribution and range of species and in intermingling the 

 floras of different localities. This grass closely resembles its con- 

 gener, E. pilosa, from which it is most readily distinguished by 

 the naked axils of its panicle. 



Eragrostis capillaris, JVees. 



Ithaca. Dudley. A dwarf form three or four inches high. 



Cheilanthes vestita, Sw. 



Two miles below Poughkeepsie on the east side of the river. It 

 occurs also on the west side of the river, but in blasting the rocks 

 for the West Shore railroad, its station may have been destroyed.
