Description. — "S. foliis oblongo-ovatis, basi attenuatis, apice 

 leviter emarginatis, integerrimis, nervo medio debili, secundariis 

 snbtilissimis." Heer 1883. 



These leaves are oblong-ovate in outline, with a decidedly 

 emarginate rather than a retuse apex. They are 6 cm. to 8.2 cm. 

 in length by 2.8 cm. to 3.3 cm. in greatest breadth, which is 

 toward the full, cuneate base. Petiole short and reasonably 

 stout. Secondaries mostly obsolete, apparently numerous, 

 slightly curved, parallel. 



Prof. Newbeny was quite positive that these leaves were dif- 

 ferent from those which he referred to Lirodendropsis, although 

 he compared them to Liriodendropsis simplex as well as to 

 Liriodendron Meekii Heer and various forms of Legurninosites 

 He thought that the angular apical points served to distinguish 

 Liriodendropsis simplex, but this character is far from constant 

 in the abundant Long Island material. 



The type material came from the Patoot beds of Greenland, 

 and this species is also recorded from Glen Cove, Long Island, as 

 well as Woodbridge, N. J. 



Occurrence. — Woodbridge. 



Collections. — N. Y. Botanical Garden.
