Delphinium ajacis L. 



Near Niagara Falls. August. E. M. Wilcox. This is an iutro- 

 duced plaut, which is cultivated for its flowers, but it sometimes 

 escapes froui cultivation. It resembles the closely allied D. 

 c o n s o 1 i d a , from which it may be distinguished by its pubes- 

 cent seed vessels. 



Hypericum boreale (Britton) Bickn. 



Shore of Piseco lake. August. Closely related to the common 

 H. m u t i 1 u m but separable from it by the stem, which is 

 scarcely branched, except at the top, by the small bracts of the 

 cymes being similar in shape to the leaves and specially by the 

 seed vessels, which are decidedly longer than the sepals. 



Vicia angustifolia Roth 



Adams, Jefferson co. June. This is closely related to V. 

 sativa, the common vetch, as a variety of which it is recorded 

 in 46th Museum report, p. 122. It is no\\' considered a valid 

 species and may be separated from its near rehitive by its more 

 narrow linear or oblong, pointed leaflets. 



Kneiffia longipedicellata Small 



Sandy soil near Eastport, Suffolk co. August. A peculiar 



form having a flexuous much branched stem and leaves a little 



broader than in the typical form. A specimen collected near 



Quogue more nearly represents the typical form. The large 



flower and long peduncle are distinguishing characters of the 



species. 



Lactuca virosa L. 



This introduced plant is rapidly spreading and is already found 

 growing freely in waste places about many of our cities and 

 villages. It was formerly confused with L. s c a r i o 1 a , a species 

 which it closely resembles and which may be distinguished by its 

 lower leaves being sinuate or sinuate pinnatifid and by its pale 

 achenes. Specimens of this species were collected near Trenton 

 Falls in August.
