300 Contributions to Western Botany. [ZOE 
line wide, linear, older ones glabrous and varnished, edges revolute 
nearly to midrib, and so nearly cylindrical, very abruptly acute; 
petiole 1% line long; leaves fascicled at the ends of branchlets; in- 
tricately branched; bark white throughout, or nearly so. Others 
from the same place have the leaves 4 lines long, narrowly elliptical, 
nearly glabrous, and the under surface not chalky white, as is usual 
in the type. 
June 9, 1891, Furber, Eastern Nevada. Branchlets more slender; 
leaves less crowded, 2 to 6 lines long, younger ones white silky 
villous, and both sides alike, narrowly oblong, blunt, some scarcely 
revolute; tails an inch long, the upper half bare, plumose part with 
hairs 2 lines long and densely white, the hairs gradually growing 
shorter to the beardless tip. This latter is the case in all forms; 
calyx 3 lines long. 
Specimens No. 2. Leaves very short-woolly, chalky white below, 
some scarcely revolute; calyx 4 lines long; otherwise as the above. 
Specimens No. 3. Leaves densely white woolly, oblong linear, 
3 to 4 lines long, 1 to 2 wide, broadest not revolute. 
There are many other forms, but those given show the general © 
trend. The variety is usually a densely and intricately branched 
shrub, 3 to 5 feet high, with light gray bark, abounding in rocky 
ravines and cliffs and rocky hillsides, forming a large part of the 
brush of the. low mountains. It abounds below 7,000 feet altitude, 
but rarely grows much higher. The type begins at about 7,000 
feet altitude, and runs up to subalpine on the higher mountains. 
On Ruby Hill, at 9,000 feet altitude, I saw the type matted like the 
firs near timber line on the loftiest mountains. Both the type and 
the variety are very much affected by the soil and moisture where 
they grow. The variety seems to be a form of the type that has 
_ adapted itself to conditions that the type, from its larger surface of 
leaves, cannot do. It is strange that Watson never saw this plant 
in Nevada, where he spent a season, and where it is very common. 
It was doubtless an oversight, as he also reported that he did not 
see Juniperus Californicus var. Utahensis (as it is now called) in 
Utah, while it is the only tree on Antelope Island, and the island is 
black with it, and was when he was there camping. It is also found 
everywhere in Utah. 
RIBEs CEREUM Dougl. The flowers have a cannon-shaped valyx: 
petals white, rounded at tip; calyx tips reflexed; fruit yellowish red
