DESCRIPTION OF SPECIES. 3 
No memorandum in regard to locality or supposed botanical relationship 
was found in connection with either the figure or the specimen.—A. .H. 
Order SAPOTACEAE. 
SAPOTACITES RETUSUS Heer. 
Pl. LIII, figs. 5, 6. 
Sapotacites retusus Heer, Fl. Foss. Arct., Vol. VII, p. 32, Pl. LXI, fig. 10. 
In the Amboy Clays, as in the Atane beds in Greenland, numerous 
emarginate leaves are found which correspond to several of those figured 
by Heer in his Flora Fossilis Arctica as either forms of Liriodendron Meekii 
(Vol. VI, Abth. II, Pl. XXII) or regarded by him as species of Colutea, 
Sapotacites, or Leguminosites. Among others is a long-ovate leaf, of which 
a figure is now given, that corresponds closely with the one figured by Heer 
as Sapotacites retusus. In some cases the emargination is much deeper 
than in others, and such leaves would probably be referred by Heer to his 
Liriodendron Meekii, but we have reason to believe that this leaf is not 
a Liriodendron. We have several species of that genus represented in the 
Amboy Clays, some of which have been already described in the Bulletin 
of the Torrey Botanical Club; and while one of these, which I have 
included among the varieties of Liriodendropsis simplex, has the long-ovoid 
and lanceolate form of the leaves under consideration, it always has the 
margination angular and the lateral points acute. 
I should also say that the forms figured on Heer’s Pl. XXIII of Vol. 
VI, formerly described by him as Leguminosites Marcouanus and Sapotacites 
obcordatus, but later considered by him as forms of Liriodendron Meekii, 
have not been found in the Amboy Clays, and so far as known at present 
they are confined to the Dakota sandstones of the West, and they should not, 
in my judgment, be regarded as varieties of any species of Liriodendron. 
Locality: Woodbridge.
