io6 Muhlenbergia, Volume 7 



The range is not heavily timbered, and at a distance gives 

 the impression of being treeless at most places. About the 

 heads of canyons, especially on north exposures, is found a scat- 

 tered growth of Pinus fiexilis^ and in some places, as back of 

 Lamoille, it even occurs in fair sized groves. Pinus Balfonriana 

 is reported by Watson as growing sparingly on the summit. He 

 also records Picea Engelmanni^ but that too was not seen by me. 



The months of July, August and September, 1868, were 

 spent on and about the Ruby or East Humboldt mountains as 

 they were then called, by Sereno Watson, botanist to the expe- 

 dition which explored the region designated as the fortieth par- 

 allel. From July nth to August 24th, Fort Ruby, at the ex- 

 treme southern end of the range, was the base for operations. 

 From August 24th to September 20th, the northern part of the 

 range was explored. 



In 1893 and again iu 1896, Dr. E. L. Greene spent a few 



days here, presumably in the Clover mountain part of the range, 

 and occasional references by Marcus E. Jones, indicate that he 

 also has collected there. 



Watson collected a large number of types in this region, 

 and Greene has published a number from the same source. 

 Wishing to obtain material of these species from type locality 

 as well as to gain a better botanical knowledge of this part of 

 the. state, I was sent thither by the Nevada Agricultural Exper- 

 iment Station in 1908. 



Work was begun on July 17th near Deeth, two weeks being 

 spent at the hospitable ranch of Mr. William Smiley, and from 

 here the northern end of the Clover mountains was visited, as 

 well as the meadows at Deeth and the Humboldt Wells. 



Mr. Smiley's ranch lies at the very foot of the Clover moun- 

 tains about seven miles southeast of Deeth, and varies in alti- 

 tude from about 5750 to 5900 feet. It is irrigated from a small 

 stream flowing from one of the canyons, and partly surrounded 

 by uncultivated sage brush land. .Here is located the only wood 

 lot I have so far ^q^w in Nevada, made up principally of elms, 

 poplars and willows. My tent was pitched within its borders, 

 and it proved to l)e a very pleasant camping place.
