«• Leucxna glauca (Linnseus) Bentham is now believed to occur naturally only on the Is' and of Key 

 West, where I have seen it only as a shrub, and for this reason it is excluded from our tree flora. However, 

 Britton and Shafer (op. cit., 527) include it, with the statement, " A shrub, rarely becoming a tree 10 meters 

 tall." Leucarna greggii S. Watson, the name which properly designates our West Texas tree, was tech- 

 nically published in 1888, but subsequently it appears to have been overlooked. 



M Prosopis juliflora (Swartz) de Candolle as it occurs in western Texas and in eastern New Mexico is 

 commonly a low, shrubby plant growing from a huge root system, but sometimes becoming a small tree.
