50096. Prosopis dulcis DC. Mimosacese. 



A thorny tree, 60 feet high, with very deep roots, adapted for live fences. 

 The hard, strong, durable wood when polished resembles mahogany. The 

 sweetish pods, rich in protein, grape sugar, starch, pectin, potash, lime, and

 beautiful wood much used in this region for furniture, doors, windows, car- 

 riages, etc. (Adapted from Lillo, Contribucion al Conocimiento de los Arholes 

 de la Argentina, p. 53.) 



50099. Prosopis panta Hieron. Mimosaceae.

 Cachapoal River. The pods are much relished by animals. The wood is 

 violet-brown, very hard, and used by wheelwrights; it gives very good char- 

 coal. The seed is much appreciated medicinally for cardiac troubles on account 

 of the tannin it contains. (Adapted from Bulletin de la Societe Nationale
