the number and depth of the divisions. A frequent form of calyx is 
one divided to the base on the side next to the rachis, the margin two 
or three-lobed or parted. The segments are smooth or slightly scab- 
rous with a few minute scattered hairs, the tips copiously fringed with 
long, flattish, twisted or curling hairs. Stamens four or five, about the 
length of the calyx lobes. Anthers longer than the filaments, oblong, 
with a cordate base and blunt or emarginate apex which is sometimes 
apiculate. 
The pistillate flowers are from the axils of leaves on fresh shoots 
of the year, their peduncles stout and very tomentose, and one to 
three-flowered. The calyx is tubular campanulate, the upper part 
generally strongly tinged with vinous red, and is four to seven-lobed, 
cleft or parted, the margin laciniate hairy and fringed with usually 
long hairs. Styles three, spreading or recurved, thick and flattish, 
hairy near the base, the enlarged rounded or knoblike stigmas dark 
colored and slightly two-lobed.. The involucral scales are hairy, coml- 
monly reddish, mostly broad and blunt-pointed. There is often 4 
basal lanceolate and bract-like scale. The acorns are single or in paifs, 
the cup turbinate or cup-shaped, thinnish, covering one third to one 
half or more of the nut and commonly tapering into a peduncle 
8-15™" long. In some forms the cup is thickened near the margi?, 
forming a kind of shoulder (plate IT, f). The scales are narrow-ovate, 
obtuse or truncate, brownish, pubescent, closely appressed, sometimes 
a little loosened near the rim on drying. The margin is thin, hyaline, 
and slightly eroded. The cup within is puberulent, pale brown, the 
thin margin with a more deeply colored, reddish or yellowish ring: 
The nut is chestnut-brown, often striped with darker lines, puberulent 
12-20" long, ro-r15™™ wide, ellipsoidal, varying from a cylindrical _ 
a shorter somewhat globular form. The kernel is pale yellow 
bitter, at least to the after taste. ee
