DESCRIPTION OF SPECIES. 69 
united under one specific name. Hence it has seemed the wisest course to 
leave this specific name for future determination, when more and_ better 
material may assist us in arriving at a definite conclusion. 
The exact locality I have not been able to ascertain—A. H. 
Order FAGACE.

Quercus JounstruPI Heer?.

Quercus Johnstrupi Heer, Fl. Foss. Arct., Vol. VII, p. 24, Pl. LVI, figs. 7-10, 11, 11b, 12a. 
This is a somewhat obscure impression of the summit or upper half of 
a notched leaf which, when complete, must have been very like some of the 
specimens of the species to which it is provisionally referred, and which is 
figured and described in Heer’s Flora Fossilis Arctica (loc. cit.). Without 
more material it will be impossible to assert the identity of the New Jersey 
and Greenland plants, but they present no differences which would justify 
us in separating them. 
Locality: Sayreville. 
Order ULMACE. 
Puanera Kyowxrontana Hollick n. sp. 
Pl. XLII, figs. 1-4. 
Leaves 2.5™ to 5™ in length by 1™ to 2° in breadth, ovate, pointed; 
margins coarsely serrate; nervation distinct, midrib flexuous, lateral nerves 
numerous, simple, parallel, given off at an acute angle and terminating in 
the serrations of the edges. 
Of this little leaf quite a number of specimens are contained in the 
collection, but none in a very good state of preservation. They are quite 
elm-like in character, and closely resemble some of the species of Planera 
that have been described from the Upper Cretaceous and Tertiary rocks. 
Locality: Woodbridge. 
' Named for Dr. F. H. Knowlton on information from Prof. Lester F. Ward that the name P. antiqua, 
which Dr, Newberry had given to this leaf, was preoccupied.—A. H.
