2. Anemone tridentata, Vahl. 



A. tridentata, Vahl, Symb., iii, 74, t. 65 (1794). 

 A.fumariozfolia, Juss., Ann. Mus., iii, 247, t. 20, f. 2 (1804). 



Erect, slender, more or less appressed-pubescent, 6-45 cm. high. Radical 

 leaves slender-petioled, repeatedly divided into oblong or linear, acute, den- 

 tate or entire segments ; leaves of the involucre sessile, similarly divided into- 

 narrowly linear or filiform segments; flower solitary, white (?), 12-25 mm. 

 broad ; sepals 5-16, linear-oblong, obtuse or obtusish ; head of fruit 16-25 

 mm. long ; style short. 



Distrib. Southern Brazil, Uruguay, the Argentine Republic, and 

 eastern Chili and Bolivia. Brazil: (St. Hilaire; Sellow, 1161). 

 Uruguay: Montevideo (Commerson ; Courbon, 120; Fox, 366; 

 Gibert, 141; Lorentz, 1052; Gillies; King). Argentine: (Hierony- 

 mus, 162). Chili: (Lechler, 2798); Nuble (Philippi). Bolivia: 

 Tomina (Weddell); La Banca (Pearce); Sorata (Mandon, 868); 

 La Paz (Rusby, 1753). 



Closely related to A. decapetala, differing in its finely divided 

 radical leaves, which are often of the aspect of those of some 

 Thalictrums. 



I have not seen Yahl's specimen, but his figure and description 

 are entirely satisfactory. The type of A. fumariaefolia, Juss., is 

 in the Herbarium of the Musee d'Histoire Naturelle at Paris.

 globose or slightly elongated tuber. Radical leaves petioled, ternate, the 

 divisions short-stalked or sessile, cleft or pinnatified into linear or oblong, 

 sometimes cuneate lobes and segments ; leaves of the involucre similarly 

 divided on short, broad petioles or sessile ; flowers purple or nearly white, 

 1.5-3 cm. broad ; sepals 10-20, linear-oblong, obtuse, more or less pubescent 

 on the exterior ; head of fruit ovoid, l|-2 cm. long; style subulate, usually 

 less than 1 mm. long.
