172 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



Tortugas Mountain. F10. 



A low, rounded, limestone mountain standing on the mesa about 3 

 miles east of the Agricultural College, Dona Ana County. It is a 

 most interesting place botanically, because its flora is quite different 

 from that of the surrounding mesa and from that of the main part of 

 the Organ Mountains. Professor Wooton and others connected with 

 the Agricultural College have collected here frequently. 

 Linum vernale. 



Truchas Peaks. Altitude, 3,982 meters, H3. 



A group containing the highest peaks in New Mexico, in the Pecos 

 River National Forest, on the line between Mora and Rio Arriba 

 counties. They are the only mountains in the Territory upon which 

 snow usually remains all summer. Professor and Mrs. T. D. A. Cock- 

 erell visited the locality in 1902 and the writer collected there in 

 August, 1908. These peaks are one of the most interesting collecting 

 grounds in New Mexico, and are reached without great difficulty by 

 going up the Pecos River from the village of Pecos. 



Mertensia caelestina. 



Tncuracari Hills. L5. 



A low range of hills in Quay County just east of the present town 

 of Tucumcari, visited by Bigelow in 1853. 



Opuntia davisii. 



Tularosa Creek. G-9. 



There are two streams of this name in New Mexico, one in the 

 northern part of the Gila National Forest in Socorro County flowing 

 into the Frisco, and the other, the one referred to in this paper, in 

 northeastern Otero County, rising between the White and Sacra- 

 mento ranges and flowing down past the Mescalero Agency and the 

 town of Tularosa out upon the plains where it disappears. Professor 

 Wooton has collected along the stream. 



Gaura neomexicana . Lesquerella aurea. 



Valverde. E8. 



Wislizenus, who collected here, speaks of this as "the mud walls of 

 a deserted Mexican village" on the east bank of the Rio Grande about 

 30 miles below Socorro. 



Dithyraea wislizeni. 



White Mountains. G8. 



An extensive range, the highest in southern New Mexico and the 



highest to be found anywhere in the Territory outside the Pecos River 



National Forest, lying in the southern part of Lincoln and the north-
