Hab. Woods In Canada. Michaux. — I possess no Canadian specimens of this plant. As seen in the 

 Herbarium, and without fruit, it is hardly to be distin^iished from C. alba, except by its alternate leaves 

 and slender petioles. All the other Comi have the leaves opposite. The fruit is purple, smaller than iu C. 



alba.

Hab. Canada. Pursh. — Drupes white. L*Heritier says this is most distinct in the cymes being 

 elongated into a panicle or thyrsus. The cyme in C. alba is sometimes a little elongated, and then I do not 

 see how C. paniculata is distinguishable from it. Mr Elliott says he has seen specimens which appear to 

 connect this with C. stricta. What 1 have received from Mr. Schweiaitz and Dr. Torrey, as C. paniculata, 

 appears to me to be in no way different from C. alba. 



3. C. stricta; ramis strictis, foliis ovatis acuminatis utrinque viridibus, adultis glabris
