198 MR. BUNBURY ON THE VEGETATION OF BUENOS AYRES. 
Daubentonia punicea, stated by Cavanilles to be a native of “New Spain,” was observed 
by Mr. Fox to grow wild, sparingly, on the bank of the Rio de la Plata, below Buenos 
Ayres, and in great abundance and beauty on the banks of the Uruguay, near its mouth. 
It is certainly quite possible that the plant may be common to both countries, but it is 
also, I think, possible that Cavanilles, who saw it only ina botanic garden, may have been 
misinformed as to its native country, and that the Argentine region may have an exclusive 
claim to it. 
Several European Leguminose are naturalized at Buenos Ayres; they are chiefly Tri- 
Jolieæ, in particular Medicago sativa and denticulata, Trifolium repens, Melilotus parvi- 
flora. 
Indigofera Anil, apparently a general plant thoughout the hotter parts of America, was 
observed by Mr. Fox to be common all through South Brazil and the Banda Oriental, but 
not to occur south of the Rio de la Plata. _Æschynomene ciliata ranges at least from 
Guiana to Buenos Ayres, and, as Mr. Bentham observes, it is scarcely distinguishable from 
the North American ZZ. hispida, which is found as far north as Philadelphia. Another 
Æschynomene, from Buenos Ayres, seems to agree with the Æ. conferta from British 
Guiana.
