stage was brownish and woody in texture, The first scalelike 
leaves on the stem were pubescent and alternately arranged. 
The young stem also was pubescent. The trichomes of the stem 
are long, slender and pointed, straight or curved, mostly singly, 
walls white, contents brown. The trichomes of the leaves are like 
those on the stem generally, only one, though sometimes grouped 
in twos or threes, not strictly stellate. The later and upper 
leaves were penni-nerved and sharply dentate, the teeth becom- 
ing gradually larger toward the base, pubescent on upper and 
lower surface, scattered, simple, general form somewhat spatu- 
late. The leaves below are glaucous. During the month of 
January the leaves dropped and the young twigs remained in 
this condition for eight weeks, when leaves again began to ap-

pear. The first leaves were penni-nerved, green on both sides, 
somewhat more shiny on the upper surface, pubescent on promi- 
nent veins and midribs, stipules soon falling. On May tenth 
these seedlings had reached a height of five to six inches. 
The acorns of this species germinate in about the same per- 
centage that those of the white oak do. On April 13 the total 
germination was 75 per cent. There is probably little reger- 
mination in any of the oaks. When the hypocotyl and radicle 
do not penetrate the soil drying will destroy the plumule. We 
received from Mr. J. H. Frazier some acorns with the hypocotyl 
two inches long. These acorns were placed in damp sphagnum
