[Taxacom] "Prosopis chilensis" in the US of A

[Doug Yanega]

I'm having trouble resolving something with a large number of host 
plant records from California and Arizona; there are hundreds of 
records listed on "Prosopis chilensis" but they are no newer than 
1961. It appears that Prosopis velutina used to be considered a 
variety (not even a subspecies) of P. chilensis, though it is 
presently considered a separate species. Am I correct in assuming 
that all records of P. chilensis from the US are in fact P. velutina, 
or does genuine P. chilensis actually live in the wild in the US? I 
can find nothing online definitively indicating the latter: nearly 
all the evidence for P. chilensis in the US seems to be based on old 
IDs before velutina was recognized as a species (sort of like all the 
records for Larrea divaricata from the US).

Thanks in advance,
