of the succeeding spring, and with a common magnifier, even the 

 stamens may be counted. 



The Sauguinaria is smooth throughout. The leaves grow on 

 long channelled petioles. When spread out, they are reniform 

 or heart shaped, with larg-e, roundish lobes separated by obtuse 

 sinuses. The under side is strongly reticulated with veins, it is 

 paler than the upper, and at length becomes glaucous. The 

 scape is round, rises in front of the petiole, and is infolded by 

 the young leaf. The calyx consists of two concave, ovate, 

 obtuse leaves, which are perfect in the bud, but fall off when 

 the corolla expands. Petals eight, spreading, concave, obtuse, 

 the alternate or external ones longer, so that the flower has a 

 square appearance. This is its natural character, although 

 cultivation sometimes increases the number of petals. Stamens 

 numerous, with oblong yellow anthers. Germ oblong, com- 

 pressed; style none; stigma thick, somewhat two lobed. Capsule 

 oblong, acute at both extremities, two valved. Seeds numer- 

 ous, roundish, compressed, dark shining red, half surrounded 

 with a peculiar while vermiform appendage, which projects at 

 the lower end. 



After the flower has fallen, the leaves, continue to grow, and 

 by midsummer have acquired so large a size as to appear like a 

 different plant. Woods and thickets, South Boston and Cam- 

 bridge. April. Perennial. 



The root is a violent emetic.

Bigelow, Medical Botany, PI. xxiii. 



Leaves two, peltate, lobed. 



The May apple has a jointed running root about half the size 

 of the finger, by which it spreads extensively in rich grounds, 

 where it gets introduced. The stem is about a foot in height, 

 and invested at its base by the sheaths which covered it when 

 in bud. It is smooth, round, and erect, dividing at top into two 

 round petioles from three to six inches long. Each petiole sup- 

 ports a large peltate, palmate leaf, smooth above, slightly pubes- 

 cent beneath, deeply divided into about seven lobes, which are
