100 TRAVELS IN' BRAZIL. 



44. Anda-a^u, Indaya^u, Purga de Gentio, in Rio 

 and S. Paulo; Cocco or Purga dos Paulistas, Frutta 

 d'Arara, in Minas Geraes. Johannesia Princeps, Velloso 

 and Gomez, Meraor. de Lisboa, 1812, p. 5., t. 1. Ajida 

 brasiliensis, Raddi, quarante piante del Brasile, p. 25. ; 

 Mart. Amoen. Bot. Monac. t. i. Two or three seeds of 

 this large tree, which Piso knew and described, prepared as 

 an emulsion, act as a very powerful and safe purgative ; 

 they seldom excite vomiting. It has been found exti-emely 

 efficacious in weakness of the lymphatic system, and parti- 

 cularly in general dropsy. 



45. GoNGONHA, in S.Paulo and Minas Geraes; Yapon, 

 Matte, Yerva de palos, on the Rio Paraguay. This 

 herb produces the Paraguay tea, which deserves to be 

 reckoned among the officinal plants as a diuretic. Ac- 

 cording to our examination it is a nondescript species,

 cantihus Jlorigeris, foliis lanceolatis longe acuminatis, basi 

 acutis glaberriviis, Jioribus congesfis, baccis globosis violaceo- 

 purpurascentibus.) The Jabuticaba is one of the most agree- 

 able fruits in Brazil, and the taste will be improved by 

 further culture. A very good wine, syrup, &c., are made 

 of it. The Jabuticabeira grows principally in the pro- 

 vinces of Rio de Janeiro, S. Paulo, and Minas Geraes. 



47. Polygala Poaya, Mart. [Pey-ennis, radice subanmdata, 

 glabra, caulibus quinquangularibiis subsimplicibus erectis, foliis 

 sparsis ovata-lanceolatis acutis trinerviis stibsessilibus,Jtoribiis 

 terminalibus laxe race?nosis cristatis. Akin to the Polygala 

 Timoutou, Aubl., which is different radice annua,foliis inferi- 

 oribus teymis, racemis jlorum deyisis.) The root of this plant, 

 which is called Poaya in S. Paulo, is an excellent emetic, 

 the effects and dose of which, when fresh, are almost the
