been preserved in its full development. It is nearly 4'^"' long' and as broad, 

 with a petiole 1.5""' long, mncli enlarged to the base.

 Pterospermites multinervis Lesq., Hajdeii's Ann. Eept., 1S71, p. 302. 



Leaves coriaceous, oblong-ovate, round, truncate at base, peltate; pri- 

 mary nerves strong; secondaries close, parallel, numerous; borders undu- 

 late or obtusely dentate. 



The leaf figured on PI. XLIII (Fig. 3), which is well preserved, shows 

 the characters of the species better than any before obtained. Though 

 somewhat smaller, it has nearly the same number of secondaries as that 

 tigured in Cret. Fl. (loc. cit.), that is, twelve pairs, besides two pairs in the 

 pelta, passing downward and curving at the borders. 



The other shown on PI. LXV (Fig. 1) is a splendid leaf preserved 

 nearly entire, round in outline, 11™ long, 10™ broad, borders nearly entire, 

 traversed by the petiole 1.5"°' above the base, which is rounded but not dis- 

 tinctly peltate. The basal border, however, is filled by the lowest second- 

 aries curved downward and branching, as in my figure of P. multinerve 

 (Cret. Fl., PI. xviiT, Fig. 1), and the nervation, number of secondaries, 

 branches, etc., are alike in both leaves, this one differing essentially by the 

 borders being mostly entire or denticulate by the slight i)ro)ections of the 

 end of the secondaries and of their liranches. Admitting this specimen as 

 1'. niiilf'nicrre, that figured on PI. XLIII, Fig. 2, appears different, as it is 

 coarseh' dentate on the borders; but this dentation may be caused by 

 erosion t>f the borders. The specimen now under consideration is a smaller 

 leaf differing by the secondaries being more distant, less mmierous, and 

 more open.
