138 Rhodora  : [May 
however, did not verify this opinion since the cup scales and the 
winter buds were more tomentose than in either of the suspected 
parents and make more probable the parentage of Q. velutina, though 
the smallness of the foliage and winter buds points more toward 
Q. coccinea. The shape of the few-lobed leaves seems to exclude 
Quercus rubra, as also the smallness of the acorns which are 
almost indistinguishable from those of Q. ¿icifolia save for the 
somewhat deeper cups and the more tomentose scales. It is there- 
fore not without hesitation that I pronounce the Oak in question a 
hybrid of Q. dicifolia and velutina but it seems to me the most 
probable explanation of this peculiar form. 
I noticed only two small trees of this hybrid standing close 
together on the left side of the path not far from the top and a little 
below the last larger Pinus rigida. The trees, of which the larger 
is about rs ft. high with a girth of 7 inches at the height of s ft. 
where the first branches appear and the smaller about 12 ft. high, 
seem to spring from a common root and are probably second growth 
from a decayed stump. ‘The main branches diverge at a more acute 
angle and are less crooked than in Q. Z/zfoZia. 
QUERCUS ILICIFOLIA Wangenh. (Q. nana Sarg.) x VELUTINA 
Lam. Small tree with spreading branches; branchlets dull yellow- 
ish or reddish brown, tomentulose when young : winter buds globose- 
ovate, obtuse, 1—14 lines long, covered with dense yellowish gray 
tomentum : leaves r4—4 inches long, rounded or cuneate at the base, 
pinnately lobed with 2—3 pairs of spreading lobes and with the 
sinuses reaching almost half way to the middle, lower lobes broadly 
triangular-ovate, entire, middle lobes triangular ovate or sometimes 
oblong-ovate with 1-3 small bristle-like teeth, upper lobes short and 
entire, small close to the apex and separated from the middle lobes 
by wide and very shallow sinuses, upper surface dull dark green, 
lower one paler and covered at maturity with a thin floccose grayish 
tomentum which often almost disappears at length except in the 
axils of the veins and along the midrib: acorns short-stalked ; cup 
top-shaped contracted at the base into a short thick scaly stalk; the 
scales densely covered with a fine yellowish gray tomentum; nut 
globose-ovoid, about 6 lines long, slightly striate, tomentulose. 
Specimens are preserved in the herbarium of the Arnold Arbore- 
tum, in the Gray Herbarium and in my own private herbarium. 
The accompanying plate kindly prepared by Mr. C. E. Faxon will 
serve to give a clearer idea of the exact shape of the foliage than a 
description possibly can. Leaves of the two other hybrid formsof Q. 
ilicifolia mentioned below are shown on the same plate for comparison.
