TWO NEW PLANTS FROM THE TERTIARY ROCKS 

 OF THE WEST 



By T. D. a. Cockerell 



Smilax labidurommae sp. nov. 



Leaf 53 mm. long and 35 wide; deltoid, with truncate base, 

 the lateral margins nearly straight, but under a lens showing 

 shallow crenulation; five principal longitudinal veins. 



Miocene shales, Florissant, Colorado, Station 14 (Wilmatte 

 P. Cockerell). On the same slab, three mm. from the leaf, is an 

 earwig, Labiduromma hormansi Scudder. The genus Smilax and 

 the family Smilacese are new to the Florissant list, but various 

 species of Smilax have been found in other American formations. 

 Smilax carbonensis n. n. {S. grandifolia Lesq., Tertiary Flora, 

 PI. IX, f. 5, from Carbon, Wyoming) is a larger leaf, with cordate 

 instead of truncate base, and convex lateral margins. It is 

 probably quite distinct from Smilacites grandifolia Unger,* 

 which as originally figured by that author, has the basal sinus 

 very deep (over 30 mm.) ; and in any event S. grandifolia Buck- 



* Chloris Protogaea, pi. XL, f. 3.
