8 THE PALEONTOLOGY OF MINNESOTA. 
[Number of Minnesota Cretaceous plants. 
The small lot of specimens of Cretaceous fossil plants obtained in Minne- 
sota by the state geologist Prof. N. H. Winchell, and described here below may serve 
as a confirmation of the above remarks. 
The number of specimens, 55, represent no less than 28 species. Of these two 
only are of gymnospermous plants; all the other, dicotyledonous, are referable to 
eighteen genera pertaining to the three great sabdivisions of the dicotyledons, the 
Apetalew, the Gamopetalew, and the Dialapetalew. 
APETALEZ. GAMOPETALE 2, DIALAPETALEZ. 
Populus. Diospyros. Aralia. 
Salix. Andromeda. Cissus. 
Alnites. Credneria. 
Platanus. Magnolia. 
Ficus. Dewalquea. 
Laurus. Juglans. 
Cinnamomum. Sapindus. 
Crateegus. 
Protophyllum. 
The relation of the genus Protophyllum, represented by two species, though 
still uncertain, is most probably to Credneria, and therefore shall be admitted in the 
Dialapetalee.
