268 Account of the Poison Plants of 
has been discovered in the southern parts of Brazil, that could be 
compared, for example, with the Tieute or the Anthiaus upar ; 
and I would even be led to believe, that there is not proportion- 
ally a greater number of noxious plants in this country, than in 
the Flora of our own. 
The plant which renders the honey of the Euxine Sea 
poisonous, is very far from being a poison of the first order, as 
is sufficiently proved by the effect, which, according to Gulden- 
stcedfs relation, it produces upon goats ; and, consequently, the 
species, whose juices frequently poison the honey of the Leche- 
guana wasp may very well be no more dangerous than the 
Azalea pontica. 
It is by no means probable, that it is an Andromeda ; for I 
have seen no species of the family of Ericaceae in the province 
of the Rio Grande, the Cisplatine province, and that of the 
Missions. It would still less be an Azalea , since not only does 
no plant of this genus grow in the different parts of America 
which I have travelled ; but also of the hundred families that 
have been indicated by M. de Jussieu in his Genera , that of 
the Ehodoracece is the only one of which I have never found a 
species in the course of my travels. 
Farther, my suspicions must fall upon a very small number of 
plants ; for the one which had rendered the honey of the wasps of 
the Rio de Santa Anna poisonous, grew in that district probably 
only in a very inconsiderable space of land, since, at the distance 
of some leagues from Rio de Santa Anna, the honey of another 
nest of the Lecheguana wasp was no longer narcotic. It is even 
pretty probable, that the plant which often renders the honey of 
the Lecheguana wasp dangerous, does not grow in any part of 
Old Paraguay ; for Azzara, who speaks of the inebriating honey 
of the bee Catabaiu , and who has very well described the nest 
of the Lecheguanas , does not say that the honey of these wasps is 
frequently dangerous. Resides, the same author furnishes us 
with no data regarding the noxious plants of Paraguay, since, 
am on ^ the pretty considerable number of vegetables belonging 
to that country, which he observed on a journey, he does not 
designate any as possessed of hurtful qualities. 
If I now consult the excellent work of M. De Candolle, upon 
the medicinal properties of plants, and the best authors who
