14 EANUNCULACEjE. (ckowfoot family.) 



1. Z. apiifolia, L'Her. — Shady banks of streams, in the mountains of 

 Pennsylvania and southward. Sherburne, New York, Dr. Douglass. Stems 

 clustered, 1° - 2° high. Leaflets cleft and toothed. — Tbc roots of this, and also 

 of the next plant, were used as a yellow dye by the aborigines. 



19. HYDRASTIS, L. Orange-root. Yellow puccoon. 



Sepals 3, petal-like, falling away when the flower opens. Petals none. Pistils 

 12 or more in a head, 2-ovuled : stigma flat, 2-lipped. Ovaries becoming a head 

 of crimson 1 -2-seeded berries in fruit. — A low perennial herb, sending up in 

 early spring, from a thick and knotted yellow rootstock, a single radical leaf, 

 and a simple hairy stem, which is 2-leaved near the summit, and terminated by 

 a single greenish-white flower. (Name perhaps from v&oop, water, and Spaco, 

 to act, alluding to the active properties of the juice.) 



1. H. Caiiadcatsis, L. — Rich woods, New York to Wisconsin and 

 southward. — Leaves rounded, heart-shaped at the base, 5 - 7-lobed, doubly 

 serrate, veiny, when full grown in summer 4' - 9' wide. 



20. AClilA, L. Baneberry. Cohosh. 



Sepals 4 or 5, falling olf when the flower expands. Petals 4- 10, small, flat, 

 spatulate, on slender claws. Stamens numerous, with slender white filaments. 

 Pistil single : stigma sessile, depressed, 2-lobed. Fruit a many-seeded berry. 

 Seeds smooth, flattened and packed horizontally iu 2 rows. — Perennials, with 

 ample 2-3-ternately compound leaves, the ovate leaflets sharply cleft aud 

 toothed, and a short and thick terminal raceme of white flowers. (Name from 

 aKTrj, the Elder, from some resemblance in the leaves.) 



1. A. spicata, L. (A. Americana, Pursh. A. braehypetala, DC.) 

 Called Herb Christopher in Europe. 



Var. rubra, Michx. (Red Baneberrt.) Petals about half the length 

 of the stamens ; pedicels slender ; berries cherry-red, oval. (A. rubra, Willd., 

 Bigel, §-c. Rich woods, New England to Penn. and Wisconsin, and northward. 

 April, May. Plant 2° high. (Eu.) 



Var. alba, Michx. (White Baneberry or Cohosh.) Petals rather 

 longer and narrower; pedicels thickened both in flower and fruit; berries milk- 

 white, short-oval or globular. (A. alba, Bic/el. A. pachypoda, Ell.) — Rich 

 woods, more common southward, extending to Virginia and Kentucky. May. — 

 Plant 2° -3° high. Pedicels in fruit often almost as thick as the main peduncle. 

 Berries sometimes tinged with red or purple, very rarely deep red {Dr. Knies- 

 kern) ; while in some districts white berries occur abundantly on slender pedi- 

 cels (Mr. Oakes, Prof. Chadboume) ; also in Siberia. Nor docs the length of the 

 petals afford marked distinctions. So that all probably belong to one species. 



21. COIICIFUGA, L. Bugbane. 



Sepals 4 or 5, falling off soon after the flower expands. Petals, or rather 

 transformed stamens, 1-8, small, on claws, 2-horned at the apex. Stamens as
