peculiar in that they are stiaif;ht l^elow and with ratlier an abrupt bend near the

I feel rather confident that this species is a native of Mexico, and that it was 

 introduced into the Philippines at the time when communication with Spain and 

 Manila was via Vera Cruz and Acapulco, in spite of the fact that it was not 

 described by Father Blanco. While it is undoubtedly allied to Prosopis juUflora, 

 and may possibly be interpreted as an extreme form of that variable species, it 

 is considered best to retain it as a distinct species for the present.

The nomenclature of this genus and species is somewhat complicated, and in 

 accepting the above binomial I have followed general usage. As to the genus, 

 Entada was first published in 1763 " but is not the earliest proposed name. 0. 

 Kuntze " has adopted the generic name Pusaetha Linn. Fl. Zeyl. (1747) 236, in 

 which he lias been followed by Taubert." but this name as a genus apparently
