220 American Species of the Genus Anemone. 



Distrih. Illinois to Nebraska, south to Georgia, Alabama, Louis- 

 iana, and Texas. 



This has been referred by nearly all recent American authors, 

 myself included, to A. decapetala, but erroneously. 



The type does not exist in Walter's Herbarium at the British 

 Museum of Natural History, but his description is satisfactory. 



oo Flowers usually 2, the second peduncle involucellate. 

 4. Anemone splienophylla, Poepp. 



A. sphenophylla, Poej^p., Fragm. Syn., 27 (1833). 



A. bicolor, Poepp. in Herb. Distr., No. 150. 



A. CMlensis, Spreng. ex Eichl., Fl. Bras., xiii (I), 152 (name only). 



A. macrorhiza, Domb. ex Eiclil., loc. cit. (name only). 



A. hilohata, Phil., Cat. PI. Vaso. Chil., 5 (?), (name only). 



Erect, more or less pubescent, 10-60 cm. Radical leaves slender-petioled 

 ternately divided, the divisions obovate, obtuse, cuneate at the base, variously 

 lobed and cleft ; leaves of the involucre short-petioled or sessile by a narrowed 

 base, palmatified into linear or oblong acute segments ; flowers commonly 2 

 (1-3), blue, the first peduncle naked, the subsequent ones involucellate; 

 sepals oblong-oval obtuse, 1-1.5 cm. long, pubescent on the outer side ; head 

 of fruit ovoid or cylindric, 2-4 cm. long ; acheuia densely woolly ; style very 

 short. 



Type in Herb. Mus. Hist. Nat. Paris. 



The species has usually been referred to A. decapetala, but is in 

 my judgment distinct, sharing the peculiarity of so many plants of 

 eastern and western America in being closely related but different. 



Distrih. Chili and the southwestern United States. Chili : 

 (Poeppig, 151 (type), 150; Bertero, 801, 46; Gaudichaud, 224; 

 Gay, 30; Dorabey; Cuming, 645; Philippi, 254; Bridges, 2G ; 

 Lechler, 3295); Juan Fernandez (Reed). United States: Utah 

 (M. E. Jones, 160t; Johnson; Parry, 1); New Mexico (Wright, 

 1304; Fendler, Mexican Boundary Survey, 8; near Silver City 

 (Greene); Arizona: Sierra Tucson (Pringle) ; Verde River Mesa 

 (Smart). 



All the Chilian plants which have been referred to A. decapetala 

 apparently belong to this species. The North American specimens 

 appear to me to be identical with the Chilian.
