Pinelands, Everglade Keys, Fla. — All year. 



The above species differs from C. brachypoda in being a peren- 

 nial with several wiry stems or branches radiating from the top 

 of the root. It lacks the congested branchlets of its relative, 

 the leaf-blades are more cordate and the capsule sparingly short- 

 hairy. The type specimen, in the herbarium of The New York 

 Botanical Garden, was collected in pinelands about the Brogdon 

 hammock near Cutler, Florida, June 19, 1913, by J. K. Small and 

 C. A. Mosier, 6347. 



A NEW OAK FROM THE GREEN RIVER EOCENE 



T. D. A. COCKERELL 



Several years ago, at station i on the Ute trail, in the Roan 

 Mountains of Colorado, I obtained a very striking and unique 

 fossil leaf which has been permitted to remain too long unde- 

 scribed. It appears black on the grey shale and shows the base 

 and petiole but lacks the apex. It certainly seems to be a 

 Quercus, distinct from any yet described. 



Quercus utensis n. sp. Leaf with a slender petiole, which is 

 41 mm. long (style of the living Asiatic Q. serrata Thunberg); 

 blade broad, broadly and abruptly truncate at base, the basal 

 truncation 35 mm. across, not symmetrical, 20 mm. being on one
