PLANTS OF UNDETERMINED FAMILY RELATIONSHIP 
CREDNERIA MACROPHYLLA Heer 
(PLaTE 170, Fic. 4) 
Credneria macrophylla Heer, Neue Denkschr. Schw. Gesellsch. 
Naturwissensch. 23? (Kreide-Fl. Moletein): 16, pl. 4. 1869. 
This specimen, except for its smaller size, is identical with the 
type of the species as figured by Heer, both in nervation and in 
the strikingly thick midrib; but, unfortunately, neither in the 
type or in our specimen is the upper part of the leaf preserved. 
It is also somewhat suggestive of Populus hyperborea Heer,* 
especially when compared with his pl. 29, f. 9, pl. 30, f. 2b, and 
pl. a1, f. ra (loc. cit.), but is larger and has much more robust 
nervation and midrib. 
The botanical relationships of the genus Credneria are not 
known and have been the subject of discussion ever since the 
time when the genus was first described,t and a number of writers 
since then have suggested its affinity with the Salicaceae, Urti- 
caceae, Hamamelidaceae, Polygonaceae, or some other widely 
separated family. 
Our specimen represents an addition to the Cretaceous flora of 
the United States as well as to that of Long Island.

found, two of which are the subject of our illustration. Thus far 
it has not been reported elsewhere than from Long Island. The
