Description. — Leaves or leaflets lanceolate to linear-lanceolate 

 in outline, relatively long and narrow, with an emarginate, usually 

 angular apex and a cuneate base. Size variable, from 6 cm. to 

 9 cm. in length by 1.9 cm', to 3 cmi. in greatest breadth, which is 

 never in the upper part of the leaf, the margins usually being 

 straight and almost parallel from the angular apical corners, 

 bowing outward slightly in the lower half of the leaf and curv- 

 ing downward to the rather long- petiole. Midrib stout. Secon- 

 daries numerous, camptodrome. Tertiaries as in the preceding 

 species. 



It may be doubted if this is anything more than a variant of 

 the preceding, but as the remains are so abundant it may repre- 

 sent a closely allied, although specifically distinct type. Hollick 

 has described two additional species in the abundant material 

 of this type contained in the insular Cretaceous flora, i. e., 

 Liriodendropsis constricta and L. spectabilis, making the latter 

 one extreme of a series of which L. angustifolia Newb. is the 

 other. The relations are obviously as pointed out, but it seem's 

 questionable, in view of the individual variation even of these 

 segregates, whether it would not have been better to have con- 

 sidered all of these forms as variations of a single species. 



The present species is abundant in the Raritan at Woodbridge, 

 and also on Marthas Vineyard and at Glen Cove, Long Island. 

 It is recorded on the identification of Prof. Ward from the 

 Tuscaloosa formation of Alabama, but the writer is unable to 

 verify the latter record.
