Centaurea jacea L. 



Douglaston, Queens co, August. Mrs M. A. Knickerbocker. 

 It has also been reported from Deerfield by Dr Haberer but I 

 have seen no specimens from that locality. The plant is some- 

 times cultivated for ornament and has escaped from cultivation* 



Arctium minus Schk. 



Near Loon lake station, July. This was formerly considered 

 a variety of A. lappa. 



Lactuca morssii Kobins. 



Clearings and waste places. North Elba and Loon lake sta- 

 tion. July. In general appearance this species resembles L. 

 canadensis and L. leucophaea. From the former 

 it may be distinguished by its purplish or violet colored flowers 

 and the shorter beaked achenia, from the latter by its snowy 



white pappus. 



Hedeoma hispida Pursh 



Thin naked soil covering rocks. Little Falls. June. Prob- 

 ably introduced from the west. J. V. Haberer. 



Panicularia laxa Scribn. 



Margin of a pond near Loon lake station. July. The speci- 

 mens have the small few-flowered spikelets of this species but 

 the upper sheaths do not overlap as in the typical form.
