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 distinguished 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 in 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 no°t
see how C. paniculata is distinguishable from it. Mr Elliott says he has seen specimens which appear to
connect this with C. stricta. What I have received from Mr. Schweinitz 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
