curve, and by the eqiiidistiiut, parallel, opposite secondaries, the lowest ]iair 

 of which are supra-basilar. These differences are marked enough to anthor- 

 ize a separation of species. 



By comparison with plants of our epoch the leaves of P. Schinijwri 

 Lesq. show affinity of character with those of Lanrns rattarmms Willd., var. 

 latifoJui, while the leaves of P. Hayana Lesq. are more like those of \'ar. 

 amjHsfifoUa Lesq. of the same species.

Oret. FL, p. 75, PI. xxviii, Fig. 1. 



Leaves large, oblong-ovate, lanceolate, pointed; borders entire ; nerva- 

 tion pinnate ; lower secondaries at a more acute angle of divergence, the 

 others distant, curving quite near the borders and following them; nervilles 

 thin. 



The leaf figured in Cret. Fl. (loc. cit.) is more complete than this 

 fragment; but this shows the nervation more distinctly, especially the more 

 acute angle of divergence of the lower pair of secondaries. As the leaves 

 of P. Leamtrana Lesq. and of Maffnolia icniufoHa Lesq. (Cret. Fl., p. 92, 

 PI. XXI, Fig. 1) have nearly the same form and the same size, tlie fragment 

 here figured is valuable in showing the difference in the character of the 

 nervation.
