Acer. ACERINEZ.. 27 
Acer Bolanderi, sp. nov. 
Pl. VIL Figs. 7-11. 
Leaves of small size, subcoriaceous, palmately three-lobed ; lateral lobes shorter than 
the middle one, entire or distantly obtusely dentate; base broadly cuneate and sub- 
cordate to the slender petiole. 
All the specimens representing this fine species have the same char- 
acters, the leaves trilobate, with borders either entire or cut along the 
sides of the lobes into a few obtuse teeth. The largest of these (Fig. 7) 
is only five and a half centimeters between the points of the lateral 
lobes; the smallest are not half as large. The lobes are in an angle 
of divergence of 30°-45°, with obtuse broad sinuses. Two species of 
the present flora of California have relation to this fossil one: Acer tripar- 
titum, Nutt. by the form of the leaves, which are, however, of larger 
size and acutely dentate; and Acer grandidentatum, whose leaves are gen- 
erally five-lobed, but which are of the same size and of the same con- 
sistence, with lobes obtusely distantly dentate, as in this fossil species. 
It is also comparable to Acer subcampestre, described by Goeppert, from 
the Miocene of Schossnitz, and to Acer Italicum, Mass., of the same for- 
mation of Italy. The affinity is, however, distant.

ILEX, Linn. 
Ilex prunifolia, sp. nov. 
SP: th Bone TUT. 3 
Leaves small, oval, obtusely pointed, rounded in narrowing to the base ; middle nerve 
thin ; secondary nerves parallel, equidistant, curved, and camptodrome ; borders dis- 
tantly obtusely dentate. 
The reference of this leaf, the only one representing the species, is not 
positively ascertainable. By the camptodrome direction of its secondary 
nerves it resembles the living 7. decidua, Walt., which has the same _ bor- 
der divisions, and in some of its leaves the same form. The base of the 
fossil leaf is, however, less narrowed and tapering.
