 and Arizona (to Santa Catalina, Santa Rita, Whetstone, Patagonia, Huachuca, 

 Chiricahua, Peloncello, and Animas Mountains) and to southern Utah; western 

 Texas (mountains). 



Xote on nomenclature. — Formerly not distinguished from Robinia neo- 

 mexicana Gray, the hairs on the fruit of which are not glandular, as is the case 

 in the variety. 



M Two forms of heartwood are produced by this species, one being an olive-brown and the other yellowish 

 gieen. The latter is considered the more valuable for commercial purposes. This difference in the color of 

 the woods has given rise to two distinct common names, the darker wood being called Black Locust and tht 

 lighter wood, Yellow Locust. No botanical characteristics have been found to distinguish the two forms.
