ence in the form of the teeth cannot be considered as specific. The 

 anthority is not refutable, being the result of the examination of a 

 number of specimens of different localities. 



FlClTS OBLANCEOLATA, SJ). nOV. 



Leaves subcoriaceous, obovate or oblanceolate, entire, taper x)ointed, 

 gradually narrowed to a short petiole, pinnately, closely nerved. 



The form of the leaves is about like that of Ficus lanceolata, in Heer, 

 (Fl. Tert. Helv., Vol. II, p. 62,) broader, however, toward the point, with 

 more numerous secondary veins. There are 14 pairs of these veins in 

 leaves 7^ cent, long, the lowest pair at an acute angle from the medial 

 one and following the borders; the superior ones, at a broader angle of 

 50°, straight to near the borders, which they follow in anastomosing in 

 successive bows. The relative position of the secondary veins i§ more 

 regular than in Heer's species. 



COCCOLOBA LAEVIGATA, sp. nOV. 



Leaves round, (obtuse?) subcoriaceous; borders entire, undulate; 

 surface, smooth ; nervation, brochidodrome. 



Only two fragments, both representing the lower part of the leaves. 

 The form of the point is merely indicated; the undulate borders, 

 rounded downward, join the petiole by a short, slightly decurrent curve. 

 The lowest secondary veins are thinner than the upper ones, the medial 

 nerve broad and flat; the details of nervation are like that of Goccoloba 

 Moridana, Mich. These leaves are related in form and nervation to 

 Ficus penninervia, Ung., as figured by Ett., FL Badoboj., PI. II, Fig. 2. 



Platanus Guillelm^j Gopp., in Eept. 1871, p. 290. 



The most common species at Carbon, where its numerous varieties 

 may be studied. One of the more marked ones is represented by small 

 broadly ovate leaves, truncate at base, scarcely lobed ; borders marked 

 with large acute teeth ; basilar lateral veins from quite near the top of 

 the petiole. 



ClNNAJIOMUM AFFINE, Lsqx. 



Mentioned above from Marshall's. The upper part of a large leaf 

 with the base destroyed, 8 cent, long, 5 cent, broad, ovate, tapering 

 into an obtuse point, the two lateral veins of the same thickness as the 

 medial one, ascending, in curving, to near the jjoint of the leaves, where 

 they connect with the medial nerve without distinct anastomosing. The 

 form is that of C. BucM, Heer, except that the broadest part is below 

 the middle, not above as in the European species. 



CiNNAMOlMUM MiSSISSIPPIENSE, Lsqx. 



Mentioned already from Golden. A number of well-preserved speci- 

 mens. 



ASIMINA EOCENICA, sp. nOV. 



Leaves lanceolate, entire, thickish, equally tapering upward to a 

 point and downward to a short petiole, penninerve, camptodrome.
