406. E. Ipecacuanha Linn. sp. pi. 653. Bot. mag. t. 1494. 

 Bigelow. med. bot. iii. t. 52. — Sandy soils in the middle and 

 northern states of North America. 



Root irregular and fleshy, very large in proportion to the plant it 

 bears, running deep into the sand, sometimes extending to the depth of 

 6 feet. The stems from 1 root, are numerous, erect, or procumbent, 

 forming large branches on the surface of the ground. They are smooth, 

 regularly dichotomous, and jointed at the forks. The leaves are in- 

 serted at the joints, opposite, sessile, smooth, having most frequently 

 an oblong shape, though different plants possess every intermediate 

 variety in the form of the leaf, from circular to linear. Their size and 

 colour are likewise variable. Flowers solitary, on long peduncles from 

 the forks of the stem. Calyx spreading, divided into 5 obtuse seg- 

 ments. Inner segments or nectaries 5, small, gibbous. Stamens 

 numerous, in 5 parcels, appearing at different times 2 or 3 together, 

 with double anthers. The fertile flowers have a large, roundish, 

 drooping, pedicelled germ, crowned with 6 revolute stigmas. Capsule 

 3-celled. — Root acts powerfully as an emetic ; in doses of from 10 to 

 20 grains it is both an emetic and cathartic; it is more active than 

 Ipecacuanha in proportion to the number of grains administered. 

 It wants, however, the peculiar mildness of that drug.
