SAPINDUS Merriami n. sp.
Pl. IX, fig. 5.
Coriaceous in texture, leaflets ovate in shape,
obtusely wedge-shaped at base, obtuse at apex, alternate on the rachis;
margin entire; midrib thin, straight; secondaries few, thin, alternate;
finer nervation not preserved.
The single example figured is all that can with
certainty be referred to this form. It consists of a portion of the
upper part of a rachis with two leaflets, neither of which is the
terminal one. The lateral ones are alternate and obtusely ovate in
shape.
This species resembles certain of the smaller
examples referred to S. obtusifolius Lesq., a and may possibly be
this, but it is smaller and has a thinner secondary nervation.
Locality.—Bridge Creek, Oregon. Collected
for the University of California. Type in Mus. Univ. Cal., No. 2506.
a Tert. Fl., p. 266, Pl. XLIX, figs 8-11, 1878.

XLIX, figs. 10, 11, 1878; Cret. and Tert. Fl., p. 235, Pl. XLVIII, figs.
5—7, 1883.
A single example that seems to belong to this
somewhat variable species. It is more like the examples figured from the
Green River group, having the narrow shape, thick midrib, and very
short petiole of those.
Locality.—Van Horn's ranch, about 12
miles west of Mount Vernon, Grant County, Oregon. Collected by Merriam's
expedition of 1900 (Mus. Univ. Cal., No. 892).
SAPINDUS ANGUSTIFOLIUS ? Lesq.
SAPINDUS ANGUSTIFOLIUS Lesq., Proc. U. S. Nat. Mus.,
Vol. XI, p. 15, 1888.
The single example referred by Lesquereux to this
species remains unique. I should incline to place it in Salix, yet, as
it is obscurely preserved, I have permitted it to remain as above, but
have questioned the correctness of the reference.
Locality.—Van Horn's ranch, about 12
miles west of Mount Vernon, Grant County, Oregon. Collected by Maj.
Charles E. Bendire (U. S. Nat. Mus., No. 2598).
SAPINDUS OREGONIANUS n. sp.
Pl. XV, fig. 3.
Leaflet coriaceous in texture, elliptical or
elliptical-obovate, very unequal-sided at base, apex destroyed; margin
perfectly entire; petiole short, thick; midrib very thick; secondaries
thin, about twelve pairs, emerging at a low angle, parallel,
camptodrome, each arching and joining the one next above; nervilles very
irregular, producing large areas between the secondaries, which are
filled by the very fine ultimate nervation.
The only specimen referred to this species lacks the
upper portion. It appears to have been about 5 cm. in length and nearly
3 cm. in width, with a petiole 4 mm. long. The nervation is well shown
in the figure.
I at first inclined to refer this to Sapindus
obtusifolius Lesq., a which has been found southeast of Green River
station, Wyoming, in beds supposed to be "Washakie" in age, and also in
the Fort Union beds of Montana and North Dakota. It has about the same
size and shape, although perhaps rather elliptical than ovate. The
principal difference is in the secondaries, these being more numerous
at a lower angle of divergence and less curved upward. The disposition
of the nervilles is much the same in both. However, these two species
are close, and possibly a series of specimens would show them to be
identical.
Locality.—Mascall beds, Van Horn's ranch,
about 12 miles west of Mount Vernon, Grant County, Oregon. Collected by
Knowlton and Merriam, July, 1901 (U. S. Nat. Mus., No. 8538).
a Tert. Fl., P. 266, Pl. XLIX, figs. 8-11, 1878.
