=6.= =Quercus stellàta= Wangenheim. Post Oak. Plate 45. Medium to large
trees; bark resembles that of the white oak except on old trees the
fissures are deeper when compared with a white oak of equal size, and
the ridges are usually broken into shorter lengths; twigs stout,
yellowish-brown at first, remaining this color more or less to the end
of the season, at first densely covered with hairs which remain
throughout the season, and usually one year old branchlets are more or
less tomentose; leaves on hairy petioles 0.3-3 cm. long, generally about
1 cm. long; leaves obovate in outline, commonly 1-2 dm. long and about
2/3 as wide, and generally lobed into five principal lobes which are
disposed as follows: the two basal are formed by two deep sinuses just
below the middle of the leaf which cut off a large roughly triangular
portion, one angle of which forms the base, the top two angles prolonged
on each side into a rounded lobe which may be long or short; the
terminal lobe is produced by two deep sinuses which constrict the blade
at about 1/4-1/3 its length from the apex; the two basal and two
terminal sinuses form the two lateral lobes which in size are equal to
about one half of the leaf area; the lateral lobes are generally
ascending with the terminal portion usually indented with a shallow
sinus which produces two short lobes; the terminal lobe of the leaf
commonly has two or three shallow secondary lobes; all the lobes of the
leaf are rounded; base of leaf narrowed or rounded; leaves very thick at
maturity, when they first appear both surfaces are densely covered with
a yellowish pubescence, at maturity the upper surface is a dark glossy
green, and smooth or nearly so, except some leaves retain fascicles of
hairs, and the midrib and principal veins may be more or less rough
pubescent, the under surface at maturity is a gray-green, and remains
more or less densely covered with fascicles of hairs; acorns single or
in clusters, sessile or nearly so; nuts small, ovoid 10-15 mm. long and
6-10 mm. wide, inclosed for about 1/2 their length in the cup; scales
ovate, gray or reddish brown, tomentose on the back, blunt except those
near the top of the cup which are sometimes acute; kernel sweet.
