 Smilax raritanensis Berry, Bull. Torrey Club, vol. 36: 248, 1909. 



Description. — Leaves of small size, ovate elliptical in outline, 

 with entire margins, obtuselv pointed apex and slightly cuneate 

 base, 3.5 cm. to 4 cm. in length by 1.5= cm. tO' 2 cm. in breadth. 

 Primaries 3, of medium size, diverging at acute angles from 

 the extreme base, the laterals regiilarl}^ curving upward and 

 joining the midvein at the summit. Secondaries not visible ex- 

 cept I or 2 transverse internal ones, and a few curved camp- 

 todrome external ones. 



This species was identified by Prof. Newberry with Paliiirus 

 ovalis Dawson^ which it somewhat resembles and this latter 

 species has been reported by Lesquereux^ from the Dakota Group 

 and by Hollick^ from Marthas Vineyard. These occurences may 

 represent Dawson's species, but the Raritan leaves are obviously 

 different, being relatively shorter and broader and of an alto- 

 gether different aspect.
