JURASSIC PLANTS FROM KAGA, HID A, AND ECHIZEN. 49 



f.) P. laneeolatus var. brevis Schenk. 

 PL XII, fig. 18. 



Leaflets small, longly oval ; apex acute ; veins fine, about 20 in 

 number. 



A specimen from Okamigö is longly-oval in shape, 30 mm. long 

 and 11 mm. broad with the broadest part near the middle of the 

 leaflet. It is pointed at apex, and possessed of about 20 delicate 

 veins. It agrees very well in general form with one figured by 

 Schenk ( Richthof en' s China, vol. IV, p. 251, pi. L,fig. 1) from Patat- 

 shu, west of Peking in China, though ours is somewhat longer. 



g.) P. laneeolatus var. 

 PL V, fig. 5d. 



Leaflets small, abruptly narrowed above and ending in acute apex. 



A leaflet which I have here separated from others is very small 

 when compared with the leaflets of other varieties. It corresponds in 

 size to the smallest form of P. laneeolatus Eichwaldi already alluded 

 to (PI. V, fig. 5), from which it differs in having the blade quickly 

 narrowing above and ending in pointed apex. It is 24 mm. long and 

 6 mm. broad, and possesses about 20 fine veins. It may be a young 

 leaflet belonging to one of the many varieties of P. laneeolatus, which 

 however is very difficult to determine. 



31. Podozamites tenuistriatus Geyl. 

 PI. XII, fig. 19. 



Leaflets lanceolate, gradually attenuated above, suddenly nar- 

 rowed at base, acute; veins fine, 14-16 in number; interstitial veinlet s 

 very fine.
