63. Gonobol ng leavis Michs.. {AmpeUnns alihidns (Nutt) Br itt. : Ensleniaa. ) 



Climbing Milkweed, 

 Hamilton and Tippecano<? counties. "Confined to the southern coun-

 Each of these stations is of interest, as tliey very materially extend tlie 

 range of this species in tlie State. The Hamilton County locality was in 

 an abandoned roadway which had in latter years become a fence row. 

 The soil is red clay and the locality- about a mile from the river. The 

 plant maintained itself for a number of years and began to spread to tlie 

 adjacent fields. It was at last eradicated by the landowner. The vine is 

 abundant in the bottoms of The Wabash River near Lafayette, where it 

 is a bad weed in cornfields. This species is probably of wider distribu- 

 tion in the State than the recorded localities would indicate, as it is very 

 easily overlooki^l on account of the superficial resemblance of its leaves to 

 those of IjKDnotii pdiidiirdtd wifii which it grows.
