The species abound in tlio eastern and more northern parts of North America, but are few indeed 

 in California (none of the; easlern /Shuharii type), and all except one rare. Yet the following east- 

 ern species may penliance he found along tlie northern borders of the State or at great elevations. 



V. OxYCOccus, Linn., Snudl Omnha-rij, which is found round the world farther north, may 

 occur in the higher northern parts of the Sierra Nevada ; but we have seen no specimens from 

 even so far south as Puget Sound.

 er's Flora to be " plentiful in swampy grounds near the confluence of the Columbia with the 

 Pacific, where its berries are boiled and eaten by the natives under the name of Soolubic/t, Doug- 

 las." Attention is called to this, as no one has since met with this or any other Cranberry in 

 Oregon.
