DESCEIPTION OF SPECIES. 27 



PODOZAMITES StENOPUS, Sp. nOV. 



PL I, Fig. 7. 



Leaves coriaceous, with sliining surface, short, somewhat enlarged 

 below the middle, rounded at base to a thin, narrow, twisted obtuse pedicel; 

 nerves thick, distant 1'"'", curved at base in the direction of the petiole and 

 there dichotomous. 



The fragment, nearly 4'^™ long, 17""° broad below the middle, is by its 

 distinct and distant nerves related to P. laUpennis Heer,' which, however, 

 has the leaves longer and scarcely naiTowed at the broad base or point of 

 attachment. In form the fragment resembles P. tenitiuervis Heer,^ which is 

 described as having the leaves large, oblong-oval, narrowed at base, nerves 

 close and very thin. The last character evidently distinguishes it from the 

 present species, which appears distinct from any other of the genus. It is 

 also comparable to P. Hai/dciui Lesq., mentioned above, which has short 

 obtuse leaves that are curved and only slightly attenuated at base.

PoDOZAMiTES ANGUSTiFOLius (Eichw.) Scliimp. 

 PI. I, Fig. 4. 



Heer, Fl. Foss. Arct., vol. 4, pt. 1, p. 36, PI. vii. Figs. -8-11 ; PI. vin, Figs. 2e, 5; 

 Lesquereux, (Jret. and Tert. Fl., p. 28 ; Leth. Ross., vol. 2, p. 39, PI. ii, Kig. 7. 



Leaves long and narrow, somewhat falcate or ensiform, linear-lanceo- 

 late, gradually slightly narrowed upward from the middle, blunt pointed or 

 obtusely acuminate (point broken), narrowed in the same degree toward 

 the base and distinctly nerved ; nerves prominent. 



In the fragment figured, which is 9""" broad and ll"™ long, the nerves 

 are ten in number in the middle of the leaf Another fragment recently 

 sent from Kansas, and which I refer to the same sjjecies, is only 6°"° broad, 

 with twelve distinct convex nerves. The characters of these fragments 

 agree evidently with the figure of the species in Heer,* representing part of 

 a leaf of the same width, with nerves at the same distance as mentioned 

 above (1""°). The other fragments figured belong to much narrower leaves.

 Comparative Zoology, of Cambridge, Massachusetts.
