152 Rydberg : Studies on the 



about 5 cm. long, twice ternate ; divisions rhombic-cuneate in out- 

 line, ternately cleft and toothed ; teeth oblong-ovate : scape 1-3 

 dm. high, perfectly glabrous below the involucre ; peduncles finely 

 appressed silky ; involucral leaves similar to the basal ones, but 

 short-petioled and with longer lobes and teeth ; peduncle solitary 

 or a second one with a smaller involucre : sepals white or purplish, 

 8-10, oblong-linear, 1-2 cm. long, finely silky : head of fruit 

 ellipsoid, about i cm. thick and 2 cm. long : achenes densely 

 woolly: style filiform, about 1.5 mm. long. 



This is closely related to A. splicnophylla of Chili, but in that 

 species the whole scape is decidedly pubescent with spreading 

 hairs and the segments of the involucral leaves are narrower. The 

 following species belong here :

Anemone lithophila 



Perennial with a short thick rootstock : basal leaves several, 

 glabrous or nearly so, thickish, shining, somewhat glaucous ; 

 petioles 5-8 cm. long ; blades ternate ; divisions obovate-cuneate, 

 about 3 cm. long, strongly veined, deeply 3-cleft, again cleft and 

 toothed ; the ultimate segments short, oblong-oblanceolate : scape 

 1-2 dm. high, sparingly pubescent with long silky hairs : in- 

 volucral leaves subsessile or short-petioled ; divisions similar to 

 those of the basal leaves : sepals silky, ochroleucous, tinged with 

 blue, 12-15 mm. long, broadly obovate or oval : achenes densely 

 villous all over : style filiform, about 2 mm. long. 



The type was growing with A. parviflora at an altitude of 1800 

 m. As none of the specimens there had well-developed fruit and 

 the plant is intermediate between A. parviflora and A. glohosa 

 Nutt., which also grew in the neighborhood, this species may be 

 a hybrid. The strong veins and shiny glaucous leaves suggest 

 the former but the general leaf-form the latter, although the 

 segments are broader and shorter and the leaves more glabrate. 

 Watson's specimen, which resembles the type perfectly has fully 

 developed fruit, however. The type was labelled A. Tetonensis,
