MYRICA OREGONIANA n. sp.
Pl. III, fig. 4.
Leaf coriaceous, ovate-lanceolate, very unequal-sided
at base, acuminate at apex; margin coarsely toothed, the teeth upward
pointing, rather obtuse; petiole short, very strong; midrib strong,
perfectly straight; secondaries, some 10 or 12 pairs, thin, arising at
an angle of about 45°, straight, ending in the teeth; finer
nervation obscure.
The very perfect example figured, with 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 oblique
on the other side. The apex is acuminate. The length is 3.5 cm.
exclusive of the petiole, which is 3 mm. long, and the width is 1.4 cm.
The margin is very coarsely toothed.
This species is nearest to Myrica
callicomfolia Lesq. a found abundantly at Elko station, Nevada,
and Florissant, Colorado. It differs, 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).

Pl. III, fig. 2.
MYRICA n. sp., Knowlton in Merriam, Univ. Cal., Bull.
Dept. Geol., Vol. II, No. 9, 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
both base and apex. but it is the only fragment thus far obtained. It
was apparently about 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 County, Oregon. Collected by Merriam's party of 1900
(type No. 924 in Mus. Univ. Cal.).
