JURASSIC PLANTS FROM KAGA, HIDA, AND ECHIZEN. 



65 



breadth, resemble very much those described by Heer under' the 

 above name from Ust-Balei in Eastern Siberia (Beitr. z. Juraflora 

 Ostsib. u. d. Amurl., 1878, p. 8, PL I, fig. 22-27). It is very much 

 to be regretted that in nearly all of our specimens, the surface of the 

 leaf has become entirely smooth, and even in some in which we can 

 trace very faint delicate longitudinal striae, these striae are by no 

 means s<; distinct as in the Siberian specimens. 



Fig. 8, Fl. Ill, represents the longest leaf among our specimens. 

 It is complete at one end, but broken at the other. Its length is 150 

 mm. and breadth 3.5-4.5 mm. 



I obtained only one specimen from Shimamura, but a good many 

 from Ozo. 



49. Carpolithes ginkgoides m. 

 PI. X, fig. 20-23. 



Fruit ovate, sharply edged, roundel 'at base, sharply beaked at apex. 



There occur many small ovate bodies in the black shale of Ozo, 

 which are furnished with a sharp beak at the apex. This beak in 

 one specimen (fig. 22) is very long drawn out. The length of these 

 bodies is 7-1 1 mm. and the breadth 3.5-1.5 mm. They are all pro- 

 vided with a sharp longitudinal edge which is very distinct in fig. 20 

 and 23. Their surface, when examined through a magnifier, reveals 

 delicate longitudinal striae. 



These are perhaps nuts of Ginkgo, like those of Eastern Siberia, 

 considered by Heer as belonging to G. Sibirica Heer { Beitr. '2. Jura- 

 flora Ostsib. u. d. Amurl. . p. 58, PL XI, fig. 13-16). Our specimens 

 look most like fio\ 13 of Heer; however they are all much narrower in 

 form than those of Siberia. . Loc. — Ozo.
