Wing-like Appendages on the Petioles of Liriophyllum populoides 
Lesq. and Liriodendron alatum Newb., with De- 
scription of the Latter. 
By ArTHUR HOLLICK. 
(PLATES 220 AND 221.) 
The specimens upon which this paper is based were recently 
found while re-arranging some material in the geological museum 
Columbia College. One of them had been recognized by the 
“ate Professor J. S, Newberry as a new species, and upon the 
Specimen of Liriodendyon he had attached the manuscript name 
Which is here retained. The Liriophyllum was merely labeled 
eunder its generic name. The reason for not having named it spe- 
Sifically will be apparent when the discussion in regard to it is 
Teached.. I have brought them together in this paper for the 
-Teason that, although representing different geologic horizons in 
le Cretaceous formation, they are biologically closely related, and 
also because we have in these two species the first record in 
Cither genus of the peculiar appendages to the petioles to which I 
Wish to call particular attention.
