labels accompanying New Mexican plants, is the sandy plain lying

Abronia cornea. Kallstroemia brachyslylis. 



Astragalus wootoni. Phacelia intermedia. 



Fallugia paradoxa acuminata. 



Las Playas Springs. Altitude, about 1,420 meters. Bll. 



In the south-central part of Grant County. Wright passed by here 

 in 1851. 



Aster blepharophyllus. Eryngium sparganophyllum . 



las Vegas. Altitude, 1,915 meters. • 14. 



One of the largest and oldest towns in New Mexico, in the north- 

 western part of San Miguel County. It was a station on the Santa Fe 

 Trail, consequently Wislizenus and Fendler stopped here. Professor 

 Cockerell, while connected with the Normal University, made collec- 

 tions in the vicinity. 



Arenariafendleri. Malvastrum cockerellii. 



Astragalus simulans. Rosasuffulta. 



Drymaria tenella. Xanthium commune wootoni. 



las Vegas Hot Springs. Altitude, 2,010 meters. H4. 



On the Gallinas River in San Miguel County, a few miles northwest 

 of Las Vegas. Collections have been made here by G. R. Vasey, 

 F. H. Snow, Professor Cockerell, and others. 



Quercus rydbergiana. 



las Vegas Mountains. H4. 



The term applied to the east ridge of the southern prolongation of 

 the Sangre de Cristo Range. These mountains lie in the north- 

 western corner of San Miguel County, extending perhaps into Mora 

 County. They lie just east of the Santa Fe Range. They get their 

 name from the city of Las Vegas, which lies about 20 miles to the 

 southeast. Their highest peaks have an elevation of about 3,450 

 meters. The collectors here have been the same as at Las Vegas Hot 

 Springs, Harveys Ranch, and Las Vegas. 



Acer neomexicanum. Rhus sorbifolia. 



Aragallus pinetorum veganus . Thelypodium vaseyi. 



Primula angustifolia helenae. 

 Pseudocymopterus montanus multifidus. 



Llano Estacado. M8. 



This, or the English equivalent, Staked Plains, is the name given to 

 the high plateau of eastern New Mexico and northwestern Texas. 

 The region is thus referred to by Doctor Bigelow. Most of his plants 

 reported from the Llano Estacado were Texan. Pope passed over 

 the plateau, but his plants, like Bigelow's, were collected principally 

 in Texas. 



Pentstemonfendleri. Phacelia popei.
