Mesilla Valley. "E10. 



That part of the Rio Grande Valley lying within Dona Ana County 

 is designated thus. All those plants having their type localities at 

 Mesilla, Mesilla Park, Las Cruees, or in the valley near Dona Ana 

 might be listed here. 



Mirabres Mountains and River. C9 and 10. 



The Mimbres Mountains lie just south of the Black Range in the 

 eastern part of Grant County. The river of the same name rises in 

 the southern end of the Black Range and flows southward through 

 eastern Grant and northern Luna counties until it finally is lost in 

 the sand. The region was visited by Lieutenant Emory in 1847, 

 later by Thurber, Bigelow, and Wright, ami in more recent years by 

 most of those who have botanized in southwestern New Mexico.
