notched at the apex ; berries oval (otherwise as in No. 1, of which Dr. Hooker

 ward : not in Canada. June. Shrub l-3 high. 



B. (MAHONIA) AguiF6LiUM, Pursh, of Western N. America, belonging

2. CAULOPHi'LLUJa:, Michx. BLUE COHOSH. 



Sepals 6, with 3 small bractlets at the base, ovate-oblong. Petals 6 thick and 

 gland-like somewhat kidney-shaped or hooded bodies, with short claws, much 

 smaller than the sepals, one at the base of each of them. Stamens 6 : anthers 

 oblong. Pistil gibbous : style short : stigma minute and unilateral : ova 17 

 bursting soon after flowering by the pressure of the 2 erect, enlarging seeds, 

 and withering away ; the spherical seeds naked on their thick seed-stalks, look- 

 ing like drupes ; the fleshy integument turning blue : albumen of the texture of 

 horn. A perennial glabrous herb, with matted knotty rootstocks, sending up 

 in early spring a simple and naked stem, terminated by a small raceme or pani- 

 cle of yellowish-green flowers, and a little below bearing a large triternately 

 compound leaf without any common petiole (whence the name, from Kav\6s-> 

 stem, and <uXAoi/, leaf; the stem seeming to form a stalk for the great leaf). 

 Leaflets obovate-wedge-form, 2-3-lobed.

 Seeds oblong, with no aril. A perennial glabrous herb, with thick horizontal 

 rootstocks, sending up each year either a huge, centrally peltate and cut-lobed, 

 rounded, umbrella-like radical leaf on a stout stalk, or a flowering stein bearing 

 two similar (but smaller and more 2-clcft) alternate leaves which are peltate near 

 one margin, and terminated by a cyme of white flowers. (Name composed of
