258, with “cones cylindric, 6-8 inches long,” found originally in 
the San Francisco mountains, Arizona. 
PINUS MONOPHYLLA Torr. & Frem. in Fremont’s Report 
319. 1845. 
A few trees of the nut pine are found along the road be- 
tween Owens and Lee canyon at 6000 feet, but the species does 
not become plentiful until an elevation of 6500 feet is reached, 
and is best developed between 7000 and 7800 feet, although it 
is still plentiful at Sooo feet, and even ascends to nearly gooo 
feet on south slopes. Here, as nearly everywhere in Nevada, it 
is accompanied by Sadbzna utahensis. The two are equally 
plentiful.

Picea concolor Gordon, Pinetum 155. 1858. 
The white fir occurs from 8000 up to roooo feet, but is not 
plentiful above 9500 feet, being best developed between that 
elevation and 8500 feet. ‘The bark is rougher and narrower 
ridged with deeper fissures than the tree of northern Nevada, 
but I conld find no differences in the seeds or cone scales found 
on the ground under the trees. The trees are scattered over 
north slopes and in cool ravines, but never occur in pure stands. 
The Douglas fir, Pseudotsuga mucronata (Raf.) Sudw., is 
credited to the Charleston mountains in one of the government 
reports, but this is evidently an error, the white fir having been 
confused with it by some one not well acquainted with the char- 
acters of the two trees. It is hardly possible that this species 
occurs on other parts of the mountain where conditions are less 
favorable for its growth, 
JUNIPERUS SIBIRICA Burgsd. Anleit. Holz. 272. 1787. 
This prostrate shrub was plentiful on cool north slopes at 
the head of Lee canyon, in the forests of Pinus artstata from 
gooo feet up, usually near rocks. 
SABINA OCCIDENTALIS (Hook.) Heller, occurs sparingly on 
rocky south slopes between Sooo and gooo feet. It is a larger, 
miore spreading tree than .S. u/ahens?s, the fruit and leaves con- 
siderably sinaller,
