brown or with brown margins. Leaves, when bursting from the bud, 
densely whitish pubescent. As they expand they spread on rather long 
petioles like those of Q. coccinea, and are thin, light green, and soon 
smooth above, densely white puberulent beneath, retaining the pubes- 
cence longer than on the upper surface. Mature leaves in outline 
broadly oval or some slightly obovate, 9-12™ long and nearly as wide. 
They are a light glossy green above, lighter and slightly yellow tinged 
beneath ; smooth except tufts of webby hairs in the axils of the prin- 
cipal veins below, mostly confined to the axils of branches of the mid- 
vein. They are divided by two deep rounded sinuses on each side, 
which extend one-half to two-thirds of the way to the midrib. The 
lobes, except the basal, are somewhat broader above. The lobes are 
trilobed with shallow rounded sinuses, the terminal lobules three- 
toothed, the lateral one to three-toothed. The divisions all end in a 
bristle 4-7™" long. The base of the leaves is truncate or slightly 
cuneate. Petioles slender, 3-4™ long. Autumn leaves purplish, or 
spotted with purple, red, or yellow, or many of the leaves scarlet. 
Male catkins 5~8™ long, hairy; stamens 4 or 5, anthers oblong-oval, 
retuse or blunt; calyx hairy, 2-4 parted or lobed, frequently 3-parted ; 
segments oval to broad oval or often roundish; they are usually tinged 
with purple or red. Calyx of the female flower tubular, hairy, tinged 
with red, six-lobed or cleft. Styles three-parted; stigmas thick, dark 
and two-lobed. Scales at base of the flower membranaceous. Acorns 
single or in pairs on peduncles 5—10™" long. The cup is cup-shaped, 
covering about half the nut, rather thick, contracted at the edge into 
athin border, and is yellowish within. Cup scales ovate-oblong, 
rounded at the apex, slightly pubescent, pale umber colored, with thin 
margins. When dry they are sometimes loosened near the margin of 
the cup. Nut globular-ovate, 17-20" long, 15-17" wide, pale cinna- 
mon-brown to chestnut color, slightly pubescent, sometimes striped 
with darker lines. ; 
Il. A TERATOLOGICAL SPECIMEN. 
Farther south in the vicinity of Glenwood is a group of three oaks 
near the bank of Thorn creek. These have proved of special interest 
©n account of their teratological features. They are evidently devel- 
oped from the stool shoots of an older tree and of. an age that would 
permit such a tree to have been cut down since the settlement of 
the region, being 2-3™ in diameter. There were originally five,
