150 MESOZOIC FLORAS OF UNITED STATES. 



leaflets occur only in small fragments, which are not attached and show 

 no terminations. 



PL XXXVIII, Fig. 9, gives the most complete specimen. This shows 

 three fragments with the tips and bases not preserved. They are so 

 placed as to indicate that they were once attached to a common stem. 

 They are, on an average, 5 mm. wide. The nerves are the most character- 

 istic feature. They are exceedingly fine and close, being visible only with 

 the help of a lens. At least five occur in the space of 1 mm., and some- 

 times they are even closer. They are single and parallel. Fig. 10 shows 

 one of these leaflets enlarged. 



PoDOZAMiTES LANCEOLATUS MINOR (Sclienk) Heep. ?" 

 PI. XXXVIII, Figs. 11, 12. 



The Curry County beds have yielded several small fragments of 

 detached leaves that seem to be Podozamites lanceolatus minor Heer. 

 The exact character can not be made out, as the leaves are not attached 

 and their bases and ends are not preserved. The fragments agree well 

 with the small form of P. lanceolatus, regarded b}^ Heer as a distinct 

 variety and called by him var. minor. The nervation is fine, close, and 

 approximately parallel. This is another of the plants that are probably 

 common in the Curry County and Buck Mountain floras, for P. lanceolatus 

 minor is found in the Buck Mountain localities. The material from 

 Curry County is not sufficient to permit a positive identification. 



PI. XXXVIII, Fig. 11, shows the most complete leaflet natural size, 

 and Fig. 12 the same enlarged. 



Otozamites oregonensis Fontaine n. sp. 

 PI. XXXVIII, Figs. 13, 14. 



Two fragments occur in this collection, one on each of two rock 

 specimens, that seem to be a new species of Otozamites. The fragments 

 do not suffice for a complete diagnosis, but perhaps justify a description 

 of the plant as a new species. 



The most complete and largest specimen is depicted in PL XXXVIII, 

 -Fig. 13, and a smaller and less complete one is given in Fig. 14. The
