more in favor of the name here adopted. Iam not aware that 
either of the above species have yet been identified from the 
New Jersey clays, but the indications are that they are not 
uncommon on Long Island.

Under this specific name I have included a variety of forms 
referable to the one genus. Dr. J. S. Newberry, in his first 
description of the species, (Ancestors of the Tulip Tree, Bull. 
Torr. Bot. Club, XIV. 1-7, Pl. LXI., LXII.), called attention to 
the great variation in this and allied forms (L. primaevum, 
Newb.; JL. semi-alatum, Lesq.; LZ. Meekii, Heer; Supotacites 
retusus, Heer; S. Haydeni, Heer; Leguminosites Marcouanus, 
Heer; Phyllites obcordatus, Heer, etc.). Subsequently, in the 
manuscript of the Flora of the Amboy Clays, he decided that 
the forms originally described by him, under the name Lirioden- 
dron simplex, were generically distinct from Liriodendron, and a 
new genus, Liriodendropsis, was founded, to include them. The 
species was also split into two groups, the broad forms being 
called Z. simplex, and the narrower ones L. angustifolius. These 
latter are represented, in our specimens, by f. 3, Pl. V. Similar 
forms were also figured by me from Staten Island. (Paleon- 
tology of the Cretaceous Formation in Staten Island, Trans. 
N. Y. Acad. Sci. XI. Pl. II. f. 8 and 6.) The broad forms are 
by far the commonest, and are indeed the most abundant of all 
the cretaceous leaves thus far found either on Staten Island or 
Long Island, and are likewise so reported by Mr. David White 
from Gay Head, Martha’s Vineyard. (Cret. Plants from 
Martha’s Vineyard, Am. Journ. Sci. XXXIX. (1890) 93-101, 
Pl. II.) Intermediate forms are figured on Pl. V. f. 5 and 
Pl. VII. f. 3. Until such time as the Flora of the Amboy Clays is 
published, I have thought it best to retain Dr. Newberry’s only 
published name for these leaves.
