described species. Remains are fragmentary, but indicate a 

 simple ovate-lanceolate leaf 7-10 cm. long by about 2.25 

 cm. wide, with ascending camptodrome secondaries and 

 transverse tertiaries. 



RhAMNUS INAEQUILATERALIS Lesq. 



Rhajunus inaequilateralis Lesq. Fl. Dak. Group, 170. 

 fl. 3J.f. 4.-7. 1892. Rollick, Trans. N. Y. Acad. Sci. 



16: 133- /^- 13^/- S. 1897. 

 The Cliffwood forms are identical with the smaller of 

 Lesquereux's leaves. Recorded by Hollick from the Ma- 

 tawan formation ; not found by me. 



Paliurus Mill. Gard. Diet., ed. 7. 1759. 



There are only two existing species, one confined to 

 southern China and Japan, and the other to southern Europe 

 and western Asia. The fossil species are numerous, some 

 sixteen occurring on this continent ; it is pertinent to remark, 

 however, that in the absence of fruit Paliurus is practically 

 indistinguishable from Zizyp/ms or Ceanothus. 



Raritan i. Island Raritan 3, Dakota 5, Mill Creek 2, Van- 

 couver I, Laramie 4, Canadian Upper Laramie i, Denver 3, 

 Ft. Union 2, Green River 2, Miocene i. 



Heer records one from the Tertiary of Siberia, one from the 

 Island of Sachalin, one from Patoot, and three from the Ter- 

 tiary of Greenland. 



Paliurus integrifolius Hollick (?). 



Paliurus integrifolius Hollick, Bull. Torrey Club, 21 : 57.

This reference of a fragment from near Cliffwood was only 

 provisional. The specimen represents the basal fragment of 

 a leaf which is rather large for Paliurus and lacks the lat- 

 eral branches of the primaries which ought to be present in 

 the left hand portion of the specimen. It might well represent 

 the basal portion of some of the leaves from the Raritan 

 formation which Newberry referred to Cissitcs formosus Heer. 

 Not found by me.
