Syn. Caulophyllum thalictroibes. Mx. 



A smooth plant with leaves resembling a Thalictrum, but 

 many times larger. Flowers in a small racemose panicle at the 

 division of the leaf stalks. Fruit stipitate, dark blue. Accord- 

 ing to Mr. Nuttall the germ is two seeded, and the fruit becomes 

 one seeded by abortion ; so that it appears hardly necessary to 

 separate Caulophyllum from Leontice.* — "Woods, Deerfield 5
