 PI. Ill, fig. 4. 



Leaf coriaceous, ovate-lanceolate, very unequal-sided at ))a.se, acumi- 

 nate at apex; margin coarsely toothed, the teeth upward pointing, 

 rather obtuse; petiole short, very strong; midrib strong, perfectly 

 straight; secondaries, some iO or 12 pairs, thin, arising at an angle of 

 about 45'-', straight, ending in the teeth; finer nervation obscure. 



The very perfect example figured, Avith its counterpart, is all thus 

 far detected of this form. It is rather broadly ovate-lanceolate in 

 shape, cordate on one side at base and very oblicjue on the other side. 

 The ai)ex is acuminate. The length is 3.5 cm. exclusive of the petiole, 

 which is '4 nun. long, and the width is 1.4 cm. The margin is very 

 coarsely toothed. 



This species is nearest to Myrica caUicompe folia Lesq.,'' found 

 abundiintl}^ at Elko station, Nevada, and Florissant, Colorado. It 

 difiers, however, in being relatively much shorter and broader, and 

 in having much larger teeth, which are obtuse rather than flat and 

 acute. The petiole is also relatively shorter and thicker. 



Locality. — White hill, one-half mile east of original Van Horn's 

 ranch locality. Collected by Knowlton and Merriam, July, 1901 

 (U. S. Nat. Mus., No. 8532).

 p. 290, 1901. 



Leaf membranaceous, narrowly lanceolate in shape, wedge-shaped 

 at base and apparently acuminate at apex; margin coarsely and sharply 

 serrate; midrib very thick, straight; secondaries numerous, about 16 

 or 18 pairs, alternate, emerging at a low to nearly an angle of 45° in 

 the upper portion of the blade, somewhat curving upward and ending 

 in the teeth, occasionally forking before passing to the teeth; nervilles 

 strong, percurrent, at right angles to the secondaries; finer nervation 

 producing rectangular areas. 



The example figured unfortunately lacks portions of l)oth base and 

 apex, but it is the only fragment thus far obtained. It was apparently 

 a))out 8 or 9 cm. long and is exactly 2 cm. wide. It appears wholly 

 unlike anything previously described from this area. 



Locality. — One-half mile northeast of Fossil, Gilliam Count}', 

 Oregon. Collected by Merriam's party of 1900 (type No. 924 in Mus. 

 Univ. Cal.).
