17 Ribes Menziesii Pursh.

 by Menzies, not perceiving, apparently, the specimen in this collection. 



18 Ribes sp. 



In the Meteorological Journal, under date of March 27, 1806 — " The red 

 flowering currant is in bloom. This I take to be the same species I first saw 

 in the Rocky Mountains. The fruit is a deep purple berry, covered with a 

 gummy substance, and not agreeably flavored. There is another species not 

 covered with gum, which I first found on the headwaters of the Columbia, 

 about 12th of August last." The former is evidently R. sanguineum.
