A CENTURY OF BOTANICAL EXPLORATION IN MONTANA. 7 



F. V. Hayden, the geologist of the "Hayden Survey", collected 

 somewhat in botany on the Lower Yellowstone and the Big Horn in 

 1853-4. and with the Warren -Expedition of 1855-57, which 

 ascended the Yellowstone to the mouth of the Big Horn and thence 

 across to Ft. Benton. He also made collections with the Raynolds 

 Kxpedition of 1860, which ascended to the headwaters of the Mis- 

 souri and the Yellowstone. The plants of this latter expedi- 

 tion were determined and the results published by Dr. George 

 Engelmann (Trans. Am. Phil. Soc. 12: 182-212. Phila. 1862), which 

 is largely a reprint from a previous paper by Hayden (Rep. Sec. 

 War for 1858. 2:726-747). 



George Suckley, a physician, who accompanied the Stevens Ex- 

 pedition of 1853-4, collected along the Missouri and Milk rivers as 

 far as Ft. Benton, his plants being determined and the results 

 published by Dr. Gray (Pac. Ry. Surv. 12, Pt. 2: 40-49. 1860). His 

 type collection is probably at the Gray Herbarium with duplicates 

 at the National Herbarium, Washington, and the New York Botani- 

 cal Garden. 



John Pearsall accompanied the Mullan Expedition of 1858-62, 

 which followed the route up the Prickly Pear from Ft. Benton to 

 Helena and thence westward along the line now marked by the 

 Northern Pacific railway and the Coeur d'Alene branch into Idaho. 

 lie probably collected fewer than a hundred specimens in the state 

 and these appear to be now in the Gray Herb, and the N. Y. Bot. 

 ( iarden. 



David Lyall, an English Naturalist of the North American Bound- 

 ary Commission ("Oregon Boundary Commission"), collected a 

 number of species in 1861, in northwestern Montana or near the 

 Canadian line, then being established, west of the Continental Di- 

 vide. His type collection is at Kew, but a number of his speci- 

 mens are at the Gray Herb. He published his results in London 

 in 1863 (Jour. Linnsean Soc. 7: 124-144). 



Winslow J.- Howard seems to have collected somewhat in the 

 "Rocky Mountains of Montana" about 1866, as a number of his 

 specimens are found in the Gray Herbarium and at least one species 

 (Oniphalodcs Hoivardii, Gray) was named for him. 



Robert Adams and G. N. Allen were here with the Hayden Survey
