1898.] NATURAL SCIENCES OF PHILADELPHIA. 293 



With these remarks, which I trust will be found neither ungra- 

 cious nor presumptuous, I proceed to review Mr. Meehan's paper 

 from a purely geographical point of view. I take his list precisely 

 as it stands, assuming the identifications to be correct in every in- 

 stance, and raising no botanical questions whatever. I only follow 

 the zoologists' rules of nomenclature in writing all specific and sub- 

 specific names with a lower case initial letter, all personal names in 

 the genitive case with a single i, all trinomial names without the in- 

 tervention of " var." — a practice which I think most botanists would 

 like, if they could once get used to it. 



Anemone canadensis L. (A. pennsylvanica L.) 



August 17, 180If. Missouri River, close to the mouth of the 

 creek on which the Omahas resided ; now Omadi Creek, in Dakota 

 Co., Nebraska. L. & C. there August 13-20, 1804. 



Anemone quinquefolia L. 



June 15, 1806. Collins' Creek, a branch of the Kooskooskee ; 

 now Nahwah River, or Lo Lo fork of Clearwater River, in Shoshone 

 Co., Idaho. 



Clematis douglasi Hook. ft MrsuUsaima Pursh, Fl., 384. 



No date. Pursh has " plains of the Columbia, May." L. & C. 

 were not on the Columbia itself in May of either year. In May, 

 1806, they travelled by land approximately up Snake River or 

 Lewis' fork to the mouth of the Kooskooskee, lst-4th, up the Koos- 

 kooskee, 4th-13th, and were at their Camp Chopunnish, on the 

 right bank of the Kooskooskee, nearly opposite but a little below 

 the mouth of Commearp Creek, now known as Lawyer's Canon 

 Creek, till June 10th. This is a notable locality, where many plants 

 were collected in May and June, 1806. The position is in Shoshone 

 Co., across the river from, and nearly opposite, that of present 

 Kamai or Kamiah, in Nez Perces Co., Idaho. 



Delphinium menziesi DC. 



April llf., 1806. On the Columbia River, one day's journey by 

 boat below The Dalles, coming up stream. 



Dentaria tenella Pursh, Fl. 439. 



April 1, 1806. On the Columbia, at the mouth of Quicksand 

 River of L. & C, now called Sandy River. This explains the state- 

 ment of locality in Mr. Meehan's paper as " Columbia near quick- 

 sands."
