QUERCUS PHELLOS L. 
Leaves of the willow oak are common at station 850. 
QUERCUS ALBA L. 
Penhallow, Transactions of the Royal Society of Canada, Vol. X (1904), sec. 4, 
p. 74. 
The leaves of the white oak are fairly common at station 850. 
Both leaves and wood are recorded by Penhallow from the Don 
River beds of Canada, and probably the same species under the 
name of Quercus pseudo-alba is recorded by Hollick from the Sunder- 
land of Maryland. 
QUERCUS LYRATA Walt. 
Several leaves, together with four characteristic specimens of the 
acorns, of this species were found at station 850. 
QUERCUS PALUSTRIS Du Roi. 
Occurrence based on leaves from station 850. 
QUERCUS PREDIGITATA sp. nov. 
Leaves of the type of those of the Spanish oak—to which, however, 
it has seemed best to give a new name, since it is very probably the 
ancestral form, not only of this species, but of Quercus pagodaefolia 
(Ell.) Ashe as well—are abundantly represented at station 850. The 
leaves show gradations between digitata and pagodaejolia. Probably 
the same species is recorded by Knowlton from the glacial terraces at 
Morgantown, W. Va., under the old name Quercus falcata Michx. 
QUERCUS ABNORMALIS sp. nov. 
An abnormal oak leaf, bifid, with two linear lobes about one inch 
across. Based on a single specimen with the characteristic venation 
of Quercus from station 850. Leaf narrow, elongated, coriaceous; 
the blade divided about half-way up into two divergent lobes; mar- 
gins entire. 
QUERCUS MARYLANDICA Muench. 
Several leaf specimens were collected at station 850. 
QUERCUS NIGRA L. 
Several leaf specimens from station 850. 
QUERCUS PRINUS L. 
Leaves fragmentary for the most part, but common, station 850.
