Rocky Mountain FLora 153 
which it resembles most in habit ; but the achenes are wooly all 
over, not merely strigose on the back as in that species and the 
flowers are larger and lighter. The following specimens are to be 
referred here: 
Montana: Little Belt Mountains, nine miles from Barker, 
1896, /. H. Flodman, 459 (type in herb. N. Y. Bot. Garden), 
and 463; Lake Stanton, 1894, R. S. Williams. 
Utan: Uinta Mts., 1869, S. Watson, ro. 
vAnemone Piperi Britton 
Perennial with a rather slender rootstock: stem 1.5-3 dm. 
high, slender, very sparingly appressed silky ; basal leaves ternate, 
minutely appressed-puberulent when young, in age glabrous ; peti- 
oles 1~2 dm. long ; middle lobe rhombic-obovate or rhombic-cune- 
ate, coarsely toothed above the middle, 2-7 cm. long ;* the lateral 
ones broader, obliquely ovate, 2-cleft to about the middle, coarsely 
toothed : involucral leaves similar, but the lobes usually narrower : 
petioles 1-3 mm. long: pedicel 2~5.cm. long, erect in fruit, spar- 
ingly appressed silky: sepals elMiptic-obovate to oval, about 15 
mm. long, 6-8 mm. wide, white, glabrous: achenes about 4 mm. 
long, densely short-pubescent, ellipsoid, slightly compressed, taper- 
ing to both ends: beak very short. 
This has been included in A. quinquefolia and all specimens 
cited for that species from the Northwest may belong here. It 
differs, however, from that species in the form of the basal leaves, 
the erect pedicels and the short, almost straight beaks of the 
achenes, 
Ipano: Latah county, 1893, C. V. Piper, 1469 (type in herb. 
Columbia University); Craig Mountain, 1892, Sandberg, Mac-

high, simple or later in the season branched, more or less woolly 
when young: leaves twice pinnately divided, 1-1.5 dm. long, vil-
