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 in a 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 Legummosce are naturalized at Buenos Ayres ; they are chiefly Tri- 

 foliete, 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. Eox to be common all through South Brazil and the Banda Oriental, but 

 not to occur south of the Bio de la Plata. JEschynomene ciliata ranges at least from 

 Guiana to Buenos Ayres, and, as Mr. Bentham observes, it is scarcely distinguishable from 

 the North American JE. hispida, which is found as far north as Philadelphia. Another 

 ^Eschynomene, from Buenos Ayres, seems to agree with the JE. conferta from British 

 Guiana.
