FLOWERING PLANTS AND FERNS OF INDIANA. 917 



S. heterodoxum Dunal. Melon-leaved Nightshade. 



An undoubted migrant which does not seem to have spread 

 from the single station in which it was found. Its range as re- 

 ported is west of the Mississippi River. Added to the flora by 

 Dr. Hessler. 

 Monroe. 



S. Dulcamara L. Nightshade. Bittersweet. Poison Nightshade. 



Chiefly southern in its distribution in the State, growing in 

 moist shaded places. Found frequently at the edges of gardens 

 and near brick walls. Locally it is thought that the leaves of this 

 species are a virulent skin poison prouducing results as serious as 

 in the case of poisoning from Rhus radicans. Repeated experi- 

 ments upon myself and pupils failed to verify this opinion. 



Flowering from May until late in September.

LYCIUM L. 



L. vulgare (Ait. f.) Dunal. Matrimony Vine. 



Somewhat largely escaped and in places becoming troublesome. 

 It fails to establish itself in the northern part of the State, but in 

 the southern it spreads rapidly. Generally found in thickets and 

 waste places. 



Flowers from May through August.

 ter); Steuben (Bradner).
