Rosa woodsi Lindl. 



September 5, 180^. On the Missouri, immediately above the Nio- 

 brara. 



October 18, ISOlf.. On the Missouri, immediately above the Can- 

 nonball, not " at or near Fort Mandan " as Mr. Meehan states, but 

 much below that site, which was not reached till the 26th. Mr. 

 Meehan cites May 18, 1806, Camp Chopunnish, as the date on 

 which L. & C. "saw the wild roses in bloom." I find no allusion 

 to roses in the Journal of that day, but on June 10, 1806, when L. 

 & C. had just left Camp Chopunnish, they " observed two species 

 of wild rose, both of a damask-red color." These Mr. Knowlton 

 supposed to be R. nutkana and R. sayi ?, which names were accord- 

 ingly bracketed in my edition, p. 1041. 



Rubus nutkanus velutinus Brew. 



April 15, 1806. Rock Fort Camp, on the Columbia. 



Rubus spectabilis Pursh, Fl. 348, t. 16. 



March 27, 1806. Lower Columbia River, above Kalama River, 

 in the vicinity of Deer Island. The plant is not mentioned in the 

 Journal of this date, but was discovered by L. & C. in this vicinity, 

 near the mouth of the Multomah or Willamette, November 4, 

 1805 ; see my edition, p. 695. 



Spiraea discolor Pursh, Fl. 342. 



May 29, 1806. Camp Chopunnish. 

 Philadelphus lewisi Pursh, Fl. 329. 



May 6, 1806. Main Kooskooskee River, vicinity of Colter's or 

 Potlatch Creek, below mouth of the North Fork. 



July 4, 1806. " On the waters of Clark's River." This means 

 Hellgate River, between Missoula, Montana, and the mouth of Big 

 Blackfoot River, in Missoula Co., Montana. 



Ribes aureum Pursh, Fl. 164. 



July 29, 1805. Three Forks of the Missouri, junction of Jeffer- 

 son, Madison and Gallatin Rivers. Both currants and gooseberries 

 are mentioned at this date, and one species, which Mr. Knowlton 

 identified from the description as R. oxyacanthoides, is described at 

 length ; fruit large, jet black with crimson pulp, extremely acid, 

 etc. But the original mention of R. aureum is earlier in the work, 

 p. 419, July 17, 1805, when L. & C. were at Pine or Half Breed 

 Island and Rapids, a little below the mouth of Dearborn River.
