The Poisonous Plants of Indiana. 



Stanley Coulter. 



It is the purpose in this paper to consider only those plants occurring 

 within the limits of Indiana, which are said to be contact poisons. The 

 list as assembled from various authorities is sufficiently extended to raise 

 question as to the character of the facts upon which the forms were 

 included among the contact poisons. The list, as I have been able to 

 collate it, is as follows:
