 Plants of our area with "hoods purple, without pale stripes" 



Fernald refers to this species. Plants with "spathe green, without or 



with only faint stripes" Fernald refers to 



Arisaema atrorubens f. viride (Engler) Fern. (Rhodora 42: 252. 1940.) 

 Both this species and form have the under surface of the leaflets 

 glaucous. I have not seen any plant in Indiana referable to this species 

 with the under surface of the leaflets green.
