Deeply lobed pin oak leaves against a cloudy sky |
)
Pin oak (Quercus palustris)
is native to eastern parts of North America.
As a low-maintenance tree, it is also cultivated elsewhere.
An example is the ornamental tree that was planted in Reno's
Crissie Caughlin Park and has been dedicated to
George Vicari (see
obituary).
The pictures above show acorns and leaves of this tree at the
end of September 2013.
The roundish, striated acorns occur in clusters along straight
and slender twigs.
Their brownish green cups—or caps—are relatively
shallow and tighly scaled.
While the lower tree branches are drooping, the middle branches
grow at right angles and the higher ones grow upward, such as the
branch in the right-side photo:
the view of its leaves against a cloudy sky illustrates the shape
of the sharply tipped leaves with their deep lobes that extend
nearly to the midrib.
The pin oak is scientifically classified as a
red oak (section
Lobatae)
in the beech family
(Fagaceae).
Other common names for pin oak are
swamp oak,
Spanish oak and
water oak.
