Description: "Magnolia foliis niaximis, coriaciis, ovato-ellipticis, 

 apice longe attenuatis, valde acuminatis, basi in petiolum validum 

 attenuatis. nervo primario crasso. nervis secundariis valde curvatis, 

 camptodromis." Heer, 1869. (From Berry, Flora Raritan Forma- 

 tion, op. cit.). Our specimen shows, almost in perfect condition, the 

 lower half of the leaf, the apical end being broken. The base, veining, 

 and shape of the lower half very closely resemble Magnolia speciosa. 

 The attenuated apex of the leaf is one of the marked features of the 

 leaf, but this mark of identification is wanting in our specimen.

Description: Our specimen is not perfect. It is cnunpled and some- 

 what broken. It is from the U. S. National Museum, Leo. Lesquereux 

 Collection, and was identified by Lesquereux as Menispermites salin- 

 ensis Lesquereux. The impression was not completely exposed when 

 it was identified by him. Some of the overlying stone has since been
