Nysseae. 



87. Nyssa Europcea, Unf^. A fragment of a leaf which by its form, the 

 lower part of it especially, its nervation, and the thick curved petiole, is remark- 

 ably similar to the figure of that species in Ung. Sillog. PL Foss., III. p. 73, 

 Plate XXIII. figs. 6, 7, 10. 1 specimen. 



Magnoliaceae. 



88. Magnolia tenuinervis, Lx. 3 specimens. 



Nelumboneae. 



89. Nelumbium Lakesii, Lx. 2 specimens. 



Malvaceae. 



90. Pterospermites grandidentatus, sp. nov. Leaves large, sometimes very 

 large, somewhat like leaves of Platanus, palmately sub-five-nerved; the outer 

 lateral nerves being generally thin and shorter, much divided outside; lower 

 secondary nerves opposite, at a distance from the base; borders sharply dentate, 

 the teeth acute, turned upward, entered by the primary nerves and their 

 branches, while toward the apex the secondaries curve in festoons along the 

 borders, joined to the teeth bj' small anastomosing branches; nerviUes strong, 

 at right angles to the nerves. 



This definition is about the same as that given by Saporta of P. incequifolius, 

 Sez. FL, p. 402, Plate XII. figs. 3-5. One of the leaves of Golden is well pre- 

 served, and merely diff'ers from those described by the French author in the lateral 

 primary nerves somewhat incurved not quite straight. Two other specimens 

 represent merel}" the base of two leaves with five primary nerves around the 

 point of attachment of the petiole and two smaller ones declining downward 

 to the cordate base, as in the leaves of Ficus {Dombeyopsis) grandifolia, Ung. 

 3 specimens. 



9L Pterospermites, species. A mere fragment, the lower half of an oblong 1 

 comparatively small leaf, membranous, rounded and slightly emarginate at the 

 base, palmately nerved, with two paii-s of more slender nerves under the base 

 of the primary ones. The nervation is the same as in P. spectabilis, Heer, 

 Arct. FL, II. p. 480, Plate LIII. figs. 2, 3 ; but the species apparently diff'ers by 

 the nerves being more straight and the leaf apparently smaller. 1 specimen. 



Tiliaceae. 



92. Tilia antiqua ? Newby. Probably the species, though the areolation and 

 nervation of one of the leaves are much like that of Greviopsis sidcefolia, Sap., 

 FL Foss. de Sezanne, p. 407, Plate II. fig. 10. There are only two leaves, upon 

 the same specimen, and both are fnigmentary, the borders being mostly
