nervation, reticulation, and also the obsolete serration, appear much alike. In the 

 Miocene Flora, Juglana Ilecrii, Ett, is its nearest relative. The nervation and reticula- 

 tion, as figured in Hcer's Flor. Tert. Ilelvct., PL xcix, Fig. 236, are similar.

White soft clay, La Grange, Tennessee. 



Differs from the former by the short, unequally cordate, lanceolate pointed leaves, and 

 by the more prominent, obtuse, and distant teeth. The secondary nerves are of about 

 the same thickness and have the same direction, being in an open angle on the medial 

 nerve, and somewhat abruptly curving upwards from above the middle. Near the borders 

 they appear to fork, one branch entering the serrature, the other curving upwards to the 

 sinus and anastomosing. The details of nervation are rendered obscure by a coat of var- 

 nish on the specimen ; they are delineated, as far as they can be traced, in a, Fig. 7.

Red shale. 



This fine leaf, of an elongated oval form, is apparently pointed or acuminate, about one 

 foot long, with undulate borders, rounded or abruptly narrowed toward the petiole. The 

 secondary nerves are pretty near each other ; their angle of divergence, about 60°, is the 

 same in all our fossil Magnolia of this formation. I do not know of any fossil or living 

 species related to this. 



25. Magnolia latjrieolia, Spec. nov. PI. xx, Figs. 2 and 3. M. foliis oblanceolatis, acutis vol acuminatis, 

 in petiolum sonsim atteuuatis, integerrimis; nervo medio recto, angusto, nervis seoundariis numerosis, camptodro- 

 mis, ncrvulis tcnuissimis, arcolis ultimis irregularitor polygonis. 



Red shale. 



The nervation of this species is about of the same kind as that of the former, the secon- 

 dary nerves being slightly narrower and more generally opposite. But the shape of the 

 oblanccolate, tapering downward, and quite entire leaves is far different. This form of 

 the leaves distantly allies this species to Terminalia Radobqjensis, Ung. No living species 

 of ours is comparable to it. 



26. Magnolia Lesleyana, Spec, nov. PI. xxi, Figs. 1 and 2. M. foliis obovatis, brcviter obtuse acumina- 

 tis, in petiolum longo attenuatis ; nervo medio valido, transversim eroso striato ; nervis seoundariis distantibus, 

 irregularibus, secundum marginem valde curvatis.
