in Coult. and Nels., New Man. R. Mt. Bot. 131. 1909; in Piper 

 and Beattie, Fl. Northw. Coast 114. 1915; Henry, Fl. S. Br. Col. 

 97. 191 5; Rydberg, Fl. R. Mts. 192. 191 7. — S. longifolia Bebb 

 apud Coulter, Man. R. Mt. Bot. 335. 1885, pro parte, non Muhl. — 

 S. fluviatilis Howell, Fl. Northw. Am. 1:618. 1902, pro parte, non 

 Nutt. — This is a well marked species the type of which was found 

 by NuTTALL "at our station called Fort Hall, in the plains of the 

 Rocky Mountains, on alluvial lands of Lewis River of the Sho- 

 shonee." According to Ball (1909), this is old Fort Hall, near 

 Pocatello, in Bannock County, eastern Idaho, south of the present 

 Fort Hall,' near Blackfoot, in Bingham County. I have seen a 

 photograph of a cotype preserved in Herb. P. Ball (1909) gives 

 the range as follows: "Common in northeastern Oregon, eastern 

 Washington, and British Columbia as far east as the Selkirks." 

 I have not seen a specimen from the t^-pe region or other parts of 

 southern Idaho, but only from northern Idaho, Montana (Teton 

 County, Midvale, L. M. Umbach, no. 170), Alberta (Crow Nest 

 Pass and Jasper), where it seems to reach its northern limit at about 

 the 53d parallel, British Columbia (in the Chilliwack Valley and at 

 Revelstoke) , Washington (where I have seen it west of the Cascades 

 only from King County, Snoqualmie), Oregon (where it was 

 collected by Ball in 191 5 as far west as the Umpqua River, Rose- 

 burg, Douglas County, and by Applegate, no. 2224, at Ashland, 

 Jackson County), and northern and northeastern California (see 

 below), where it seems to pass into var. Bolanderiana. According to 

 Ball (Box. Gaz. 60:45, first note, 1915), S. Bolanderiana is asso- 

 ciated with S. sessilifolia at Roseburg and also farther north "on 

 the Willamette River at Corvallis," Benton County. What I have 

 seen from Oregon I take for the true S. melanopsis, which ought to 

 be looked for also in northern Utah and in western Wyoming." Its 



' This locality, however, is identical with that given for Fort Hall in Lippincott's 

 Geogr. Diet., ed. of 1855; while on the map in the Century Atlas of 191 1 old Fort 

 Hall is indicated south of the 43d parallel just north of Pocatello. Judging by Rand 

 McNally's map the whole region between the two places is called Fort Hail. 



'" There is a specimen from eastern Wyoming, Converse County, Rawhide Creek, 

 south of Patrick, August 27, 1901, H. P. Baker (m.; M.), which looks like typical S. 

 melanopsis. In Herb. C. I found a specimen from Colorado, Clear Creek County, 

 damp places along Clear Creek, 1885, H. N. Patterson (fr. adult, [sheets 5523 and 

 107801 ] ) , which clearly resembles S. melanopsis. I am not sure whether the localities 

 given are correct.
