u Primus putnila L. 



Though but a single leaf is left with the branch, it is evidently the one 

 referred to as "a smaller shrub than the ' choak' cherry. The natives ac- 

 count it good fruit." 



15 Rosa Woodsii Lindl ey. 



"October 18, 1804. The small rose of the prairies; it rises from 12 to 14 

 inches, and does not vine." Only a small branch without flower. At this 

 ■date they were at or near Fort Mandan. May 18th, at Chopunnish camp, 

 they ' saw the wild roses in bloom," but this is probably one of the forms 

 more closely related to R. cinnamomea.

" Fruit like a raspberry. Columbia, March 27, 1806." Pursh described and 

 figured I, p. H48, " on the banks of the Columbia." The Journal o{ June 10th, 

 at Chopunnish camp, notes that " purple raspberries were ripe and abundant."
