The genus Vioxa, as formerly constituted, contains an 
inconvenient number of species, on which account especi- 
ally, we have followed Venrenat, in adopting his genus 
Jonip1um; for which, by-the-by, the name of Pomsatia, 
given anteriorly by Vanpetu, ought to have been pre- 
served; but, as that of Jonip1um is used in the new Systema 
Vegetabilium now publishing, and generally, by the French 
botanists, we leave it undisturbed. 
The root of this plant is supposed to be the white Ipeca- 
cuanha formerly kept in the shops; but the only Ipeca- 
cuanha now in use is certainly the product of a very 
different plant, also a native of the same country. There 
is no doubt, however, but that the present species is fre- 
quently used in Brazil, for the cure of several disorders, 
especially the dysentery. 
Our plant was raised at the Botanic Garden, Chelsea, 
from Brazil seeds, sent us by Mr. Francis Sento, a very 
industrious and enthusiastic botanist, who has devoted 
several years to the collecting plants, and other subjects of 
Natural History, in that extensive empire. M. Aveuste 
bE Saint Hixairg, in his observations on a voyage in the 
interior of Brazil, published in the ninth volume of the 
Memoires du Museum d’Histoire Naturelle, page 329, 
asserts, that the Viota Calceolaria and Ipecacuanha of Lix- 
NEUS are the same species ; and that the Itowbou of AuBLET 
differs in nothing from the Brazil plant, except in its greater 
hairiness ; a character, which, he observes, varies extremely 
in different individuals. 'The same author supposes that 
he had discovered another species, which he calls Jonsp1u™ 
indecorum, growing with the Ipecacuanha, and differing iD 
nothing from it, but in having a corolla shorter by half than 
the calyx, and three of the filaments sterile. It is probable, 
however, that this was a mere variety from abortion, a3 
many of the violets are known to produce apetalous flowers 
later in the season, which bear seeds, even more. readily 
than the perfect blossoms; a circumstance, which, Mr. 
Anperson observed to take pl i OE 
. 2, to take place in the very individua 
from which our drawing was taken. 
We believe this plant has not before been introduced 
into any of our gardens. :
