Plants with slender rootstocks, the stems simple, one-flowered, 10-30 cm. high, sparingly 

 villous. Basal leaves long-petioled, 3-parted, the divisions broadly cuneate and obtusely lobed 

 or crenate, involucral leaves sessile, their lobes similar but usually deeper; sepals oval, 5 or 

 6, 8-12 mm. long, white or tinged with purple without; fruiting head short-ovoidj about 1 cm. 

 long; achenes densely villous all over or sometimes glabrate on the back. 



Moist soils, Hudsonian and Arctic Alpine Zones; Alaska to Labrador, south Quebec, Wisconsin, and Colo- 

 rado. Known from the Pacific States only from the Blue Mountains, eastern Oregon. Type locality: Hudson 

 Bay region. July-Aug. 



2. Anemone globosa Nutt. Globose Anemone. Fig. 1805. 



Anemone multifida var. globosa Torr. & Gray, Fl. N. Amer. 1:13. 1838. 

 Anemone globosa Nutt. ex Pritzel, Linnaea 15: 673. 1842. 



Plants from stout rootstocks, the stems erect or ascending, 1-5 dm. high, soft-villous with 

 long somewhat appressed hairs. Petioles of the basal leaves 5-12 cm. long, soft-villous; blades 

 4-10 cm. broad, 2-3 times ternately cleft, the ultimate divisions linear to narrowly lanceolate, 

 more or less long-villous ; involucral leaves similar but short-petioled ; peduncles 1-3 ; sepals 

 varying from greenish yellow to pinkish or bluish purple, oval, 6-12 mm. long; head of fruit 

 globose or ovoid ; achenes densely villous. 



Open forests or grassv slopes, often in rocky situations, Boreal Zones: Alaska to northern California, 

 east to Saskatchewan," South Dakota, and Colorado. Type locality: "Plains of the Platte and Valleys of the 

 Rocky Mountains in lat. 42°." June— July. This species is closely related to Anemone hudsoniana Richards, of 

 northeastern North America, being distinguished chiefly by its larger flowers. Anemone multifida Poir. to 

 which some botanists have referred it, is a native of southern South America and has small flowers and a 

 coarser pubescence.

 ing or somewhat appressed hairs. Basal leaves long-petioled, 3-6 cm. broad, villous, 3-4 times 

 ternate, the ultimate segments linear ; peduncles usually solitary ; sepals oval, 8-10 mm. long, 

 white and more or less tinged with blue; heads of fruit globose, about 10 mm. in diameter; 

 achenes densely woolly; styles very slender, 4-6 mm. long.
