160 Flora of Yo Semite. [ ZOE 
Of the three firs Adzes concolor grows on the steep walls and at 
their summits. 4. moéz/zs, although not frequent occurs in some 
places, as near the foot of Yo Semite fall. 4. magnifica is found along 
the whole line of the south side of the valley and in great abundance 
“near Glacier Point. 
The Douglas spruce ( Pseudotsuga Douglasii) is very abundant 
and the most valuable timber of the valley for bridging and similar 
purposes, being tough and strong. 
The graceful Zsuga Pattoniana hardly comes lower than eight 
thousand five hundred feet. It is found on benches and mountain 
sides at Cathedral Peak. 
The yew ( 7axus brevifolia) grows near the water in the cafion of 
the Merced. 
The ‘‘nutmeg-tree’’ ( Zorreya Californica) grows also in the 
cafion of the Merced but farther from the water. Neither this tree 
nor the last quite reaches the valley. 
Juniperus occidentalis grows more and more stunted and short- 
ened from the high summits of the walls nearly to the limit of vege- 
tation. There are two trees on the Cap of Liberty which are ten 
feet in diameter. 
The sugar pine (Pinus Lambertiana) and the yellow pine (P. 
ponderosa) are abundant in the valley. 
Pinus monticola grows nearly everywhere on the heights—Sen- 
tinel Dome, Cloud’s Rest, etc. 
Pinus Jeffreyt grows about the summits of the walls, and so also 
does the “ tamarack” ( Pinus contorta) which is most usually found 
near water-courses or the borders of wet meadows. The common 
name of /. contorta is like too many others very misleading, as the 
tree is very different from the Eastern one called by the same name. 
ANNUALS AND HERBACEOUS PERENNIALS. 
Of these there are of course a very much greater number than of 
the trees and shrubs, so that anything like a complete list cannot be 
given in the limits of the present paper. 
Ranunculus hystriculus Gray. This white-flowered Ranunculus 
is seldom collected but it has been brought from the crevices of wet 
rocks about Mirror Lake and in similar places at Vernal Fall and 
Yo Semite Fall. 
The “marsh marigold’’ (Caltha biflora) is abundant in the’ 
marshy meadows on the trail to the summit of Cloud’s Rest.
