RADIX IPECACUANHÆ.
Ipecacuanha Root, Ipecacuan; F. Racine d’Ipécacuanha annelee; G. Brechwurzel.
Botanical Origin—Cephaëlis[1373] Ipecacuanha A. Richard—This is a small shrub, 8 to 16 inches high, with an ascending, afterwards erect, simple stem, and somewhat creeping root, growing socially in moist and shady forests of South America, lying between 8° and 22° S. lat., especially in the Brazilian provinces of Pará, Maranhão, Pernambuco, Bahia, Espiritu Santo, Minas, Rio de Janeiro, and São Paulo. Within the last half century, it has been discovered in the vast interior province of Matto Grosso, chiefly in that part of it which forms the valley of the Rio Paraguay. From information given to Weddell,[1374] it would seem probable that the plant extends beyond the frontiers of Brazil to the Bolivian province of Chiquitos.
The root which is brought into commerce is furnished chiefly by the region lying between the towns of Cuyabá, Villa Bella, Villa Maria, and Diamantina in the province of Matto Grosso; but to some extent also by the woods in the neighbourhood of the German colony of Philadelphia on the Rio Todos os Santos, a tributary of the Mucury, north of Rio de Janeiro.
Prof. Balfour of Edinburgh, who has paid much attention to the propagation of ipecacuanha, finds that the plant exists under two varieties, of which he has published figures;[1375] they may be thus distinguished:
a. Stem woody, leaves of firm texture, elliptic or oval, wavy at the edges, with but few hairs on surface and margin. Long in cultivation: origin unknown.
b. Stem herbaceous, leaves less firm in texture, more hairy on margin, not wavy. Grows in the neighbourhood of Rio de Janeiro.
