line wide, linear, older ones glabrous and varnished, edges revolute 

 nearly to midrib, and so nearly cylindrical, very abruptly acute; 

 petiole ^2 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, i 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 Califoniicus 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 calyx; 

 petals white, rounded at tip; calyx tips reflexed; fruit yellowish red
