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. Flodnian, ^jg (type in herb. N. Y. Bot. Garden), 

 and 46J ; Lake Stanton, 1894, R. S. Williains. 



Utah: Uinta Mts., 1869, i\ Watson, 10. 



Anemone Piperi Britton 



Perennial with a rather slender rootstock : stem 1.5—3 ^"^• 

 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 elliptic-obovate to oval, about 1 5 

 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. qiiinquefolia 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. 



Idaho : Latah county, 1893, C. V. Piper, r^6g (type in herb. 

 Columbia University); Craig Mountain, 1892, Saudbcrg, Mac- 

 Doiigal & Heller, ig^. 



Washington : Kamiac Butte, 1896, A. D. E. Elmer, jgj.

Clematis Douglasii var. Jonesii Kuntze, Verh. Bot. Ver. Bran- 

 denburg, 26 : 180. 1886. 



Perennial with a thick rootstock or caudex : stems 3-6 dm. 

 high, simple or later in the season branched, more or less woolly 

 when young: leaves twice pinnately divided, i— 1.5 dm. long, vil- 

 lous when young, in age glabrate, rather firm, segments lanceolate 

 to linear-lanceo'ate, often cleft, 1-5 cm. long, acutish : flowers nod-
