Universally known anu)ng tlie natives as maeahia (literally "ashamed").

 many regions an extremely troublesome weed.

Nothing at all agreeing witli the very imperfect description has been recently 

 collected in the Philippines; it is possible that the description was based in part 

 on fragmentary material of F)i1nda scandens. It is not a Mimosa.

This species was originally described by Naves in a daily or weekly paper

 by two plates in a pamphlet entitled "Prosopis Vidaliana Naves. Descrii>ci6n de 

 la especie botanica Prosopis Vidaliana de la Flora de Filipinas" issued to 

 subscribers to the third edition of Blanco's "Flora de Filipinas." It was later 

 reduced by F.-Villar to Prosopis jiili flora (Sw.) DC. which reduction has been 

 accepted by recent authors. 



Having noticed that the Philippine material differed remarkably from the 

 single American specimen in this herbarium labeled Prosopis juliflora, 1 asked 

 Dr. J. N. Hose to compare the Philippine material in the United States National 

 Herbarium with American specimens of Prosopis. This he has kindly done, and 

 writes as follows: "I do not think your species is the same as any of our 

 United States ones. It is not the same as the one of central and southern 

 Mexico, which is probably P. dulcis. Neither do I think that it is P. juliflura of 

 the West Indies. It resembles very much some unidentified material of mine 

 from the west coast [of JNlexico]. The pods of your Pliilippine plants are rather
