Hab. Banks of rivers from Canada to near the mouth of the Mackenzie River, lat. 67°; and from the 

 shores of Hudson's Bay to the Pacific. Dr. Richardson, Drummond. Scouler, Douglas, — This seems to be 

 a very little known plant, and one that is by no means, in any publication, correctly defined. Schlechteudal 

 has, I think, confounded it with R. fascicularis of Muhlenberg, a very different species. Its nearest affinity 

 is unquestionably to R. Penmylvanicus, the R. Canadensis of Jacc[uin ; but that has oblong heads of fruit, 

 and a still shorter style.

Hab. Found with the last mentioned species, and it is equally diffused, but generally prefers the exposed 

 moist gravelly spots. — There can be no mistaking this plant, which is admirably %ured by Jacquin. How 

 it is to be distinguished from R, hispidus, I have noticed under the preceding species : but, except in the 

 fruit and flower, it must be confessed that the two are very closely allied. Carpels dotted in both.
