Hab. Nootka. Mr. Menzies. Mountains near the coast of North -West America, between the parallels 

 of 40° and 43° N. lat.? Douglas. — My character of this is drawn up from Mr. Menzies*s specimen in my 

 Herbarium. In Mr. Douglas's MSS. he notices a C. grandis from the station above-mentioned, which is 

 probably the same as the present, although it inhabits a much more southern latitude. Our plant, however, 

 it must be confessed, differs in no respect from the preceding species, except in being everywhere, even 

 upon the young leaves, entirely glabrous ; whereas C. velutinus has, on the oldest as well as the youngest 

 leaves, a delicate, short, hoary, and almost white tomentum, clothing their underside.

Hab, " North -West coast of America." Mr. Menzies, {in Herb, nostr.) New California. Eschscholtz.— 

 For a knowledge of the name of this very distinct species of Ceanothus, I am indebted to Dr. Chamisso, who 

 sent me an authentic specimen from California. Whether Mr. Menzies's plant be from California, or from 

 a higher latitude, as I rather suspect, from the manner in which its station is indicated, I will not take upon 

 me to say. The Jlowers are surrounded by densely imbricated, ovate, and acute bractetE, in the state of bud, 

 but these drop before the blossoms are expanded. The calyx, Eschscholtz describes to be blue, the petals 

 white. The whole plant turns black in drying.
