JUGLANS RUGOSA Lesq.
JUGLANS RUGOSA Lesq., Proc. U. S. Nat. Mus., Vol. XI, p. 22, 1888.
Represented by two fragments that are more or less
obscure and doubtful. There is also a single fragment obtained by the
expedition of the University of California of 1900.
Locality.Cherry Creek, Crook County,
Oregon. Collected by Maj. Charles E. Bendire (U. S. Nat. Mus., No. 2489)
and by Merriam's party of 1900 (Mus. Univ. Cal., No. 188).

Pl. III, fig. 3.
Ilex? longifolia Heer. Lesquereux, Proc. U. S.
Nat. Mus., Vol. XI, p. 21, 1888.
Leaflet coriaceous in texture, lanceolate, apparently
wedge-shaped at base and acuminate at apex; margin irregularly and
rather obscurely toothed; midrib very thick, straight; secondaries
numerous, rather close, about 20 pairs, alternate, at an angle of about
45°, somewhat arching upward, camptodrome, arching near the margin
and each joining the one next above by a thin branch, with their
nervilles on the outside passing to the marginal teeth; nervilles
numerous, percurrent, at right angles to the secondaries; finer
nervation producing a close areolation.
This particular specimen, as noted above, was
referred to Ilex longifolia Heer, a species from the Miocene of
Piedmont, but a comparison with the figure given by Heer shows that it
is undoubtedly different. The original seems to have been a much shorter
leaf, and while the Oregon specimen resembles it in a general way, there
are important differences. The teeth are different, the secondaries more
numerous, and the finer nervation is of a totally different
character.
The question of the proper generic reference of this
leaf or leaflet is an open one. It is not greatly unlike things that
have been variously referred to Ilex, Quercus, and Juglans, but on the
whole seems to have closest relationship with the latter. It will,
however, need more and better material to settle the matter
definitely.

A single example that seems to be identical with this
species, yet as the specimen is broken and is the only one, I have
preferred to question it.

JUGLANS ACUMINATA? Al. Br., Neues Jahrb., 1845, p. 170.
The Bendire collection contains a single example that
was referred by Lesquereux to this species. It does resemble this, but
may not be the same.

Oregon. Collected by Maj. Charles E. Bendire (U. S. Nat. Mus., No.

JUGLANS CRYPTATA n. sp.
Pl. VI, figs. 4, 5.
Leaflets membranaceous, broadly lanceolate, narrowed
and unequal-sided at base, apparently acuminate at apex; margin
denticulate throughout, the teeth short; rather blunt; midrib very
thick; secondaries numerous, 15 or more pairs, thin, alternate, close
below, more remote above, mostly camptodrome and sending fine branches
from the outside to the teeth; nervilles mainly percurrent and at right
angles to the secondaries.
This form is represented by three leaflets, none of
which is quite perfect. The largest, which is not figured, was probably
about 14 cm. long and is 5 cm. wide at a point evidently some distance
above the middle. The one next in size, shown in fig. 4, was 13.5 cm.
long and is 3.5 cm. wide. The smallest one, shown in fig. 5, is about 10
cm, long and a little more than 2.5 cm. in width. Neither base nor apex
is preserved in any case.
This species appears to find its greatest affinity
with Juglans Crossii Knowlton,a from Green River, Wyoming, and
other localities. The leaflets, however, are smaller, relatively
narrower, less unequal-sided, and are toothed on both sides.

by Merriam's expedition in 1900. Types in Mus. Univ. Cal., Nos. 2502,

JUGLANS, nut of.
This is clearly a nut of Juglans, but the specimen is
not well enough preserved to permit of specific determination.
Lesquereux, through whose hands this specimen once passed, was inclined
to identify it doubtfully with J. troglodytarum Heer,b but it
seems best not to venture giving it a name at present.

Juglans n. sp., Knowlton in Merriam, Univ.
Cal., Bull. Dept. Geol., Vol. II, No. 9, p. 303, 1901.
Leaflets thick in texture, lanceolate-acuminate in
shape, rather abruptly narrowed at base; margin perfectly entire; midrib
thick, rather strong; secondaries 9 to 12 pairs, strong, mainly
alternate, at an angle of about 45° much curving upward,
camptodrome, passing near the margin and often joining the one next
above; finer nervation nearly or quite obsolete.
This species is represented by a large number of
leaflets, all more or less broken, preserved in a tangled mass on two or
three pieces of matrix. The length is from 9 to 11 cm. and the width
about 2.5 cm., with occasionally one somewhat smaller.
The affinity of this species is undoubtedly with
certain of the forms of J. Schimperi Lesq.,a of the Green River
group, being of the same size and shape as the figures quoted above, but
different in having a less number of secondaries and a distinct finer
nervation. These species are closely related and a larger series might
show them to be identical.

Juglans hesperia Knowlton, Eighteenth Ann.
Rept. U. S. Geol. Survey, Pt. III, p. 723, Pl. XCIX, fig. 8, 1898.
This species was described by Lesquereux in his Flora
of the Auriferous Gravels. As to the locality whence the type specimen
came he says: "On soft laminated clay with Aralia Whitneyi,
evidently of the same age as the Chalk Bluffs of California, without
definite locality but Oregon." From these remarks it has been assumed
that the specimen actually was from the Auriferous gravels, and that
the label on it was wrong. Fortunately this type is preserved in the
paleontological collection of the University of California (No. 1798),
where I recently had opportunity of seeing it. It was at once seen that
it was on the characteristic matrix of the Van Horn's ranch locality,
and indeed the obscure labeling on the back of the specimen so
indicates.
In both the older and more recent collections from
Van Horn's ranch and vicinity I find a number of specimens, which I
refer with little hesitation to Juglans oregoniana. Most
of them are smaller than the type, being often only 7 cm. long and 2.5
cm. wide, although occasionally there is one that approaches it in
size. In shape, marginal teeth, and nervation they are practically
identical.
In 1888 Lesquereux a established his Rhus
Bendirei on two specimens, one of which is figured and is to be
taken as the type of the species. Regarding the other he says: "To these
I refer a small oblong-lanceolate leaflet, rounded in narrowing rapidly
to the point of attachment, very short petioled, with small teeth and
areolation identical." This specimen (U. S. Nat. Mus., No. 2582) is
identical with certain of the smaller leaflets of Juglans
oregoniana, and is referred to it.
In my paper on the plants of the Payette formation of
Idaho I ventured to describe,b under the name of Juglans
hesperia, a fine, large leaflet. Attention was called at the time to
the fact that it was very close to, if not identical with, Juglans
oregoniana. Since that time I have again gone over the Payette
material and have decided that the differences are not sufficient to
warrant keeping them separate.

HICORIA n. sp., Knowlton in Merriam, Univ. Cal.,
Bull. Dept. Geol., Vol. II, No. 9, p. 289, 1901.
Leaflets subcoriaceous in texture, ovate-lanceolate,
obtusely wedge shaped and slightly unequal-sided at base, acuminate at
apex; margin finely serrate, the teeth short, sharp; midrib thin,
straight; secondaries numerous, about fifteen pairs, alternate and at
somewhat irregular distances, thin, arising at various angles
(45°±) and considerably arching upward, craspedodrome, ending
in the marginal teeth; nervilles numerous, thin, percurrent, about at
right angles to the secondaries; finer nervation perfect, forming a
fine, irregular network.
This is represented at present by two examples. One
is 13 cm, long and 6 cm. wide, and the other is 12 cm. long and 5 cm,
wide.

The single fragment figured is all that was found of

specific determination.
