JURASSIC PLANTS FROM KAGA, HIDA, AND ECHIZEN. 37 



This species was described by Gey 1er, but not a single new 

 specimen was obtained referable to it. 



Fam. 4. Taeniopterideae. 

 8. Taeniopteris Brgt. 



18. Taeniopteris (?) 

 PL X, fig. 2c. 



A very small fragment of a fern (?) from the above locality 

 situated by the side of Nilssonia ozoana m. shows very fine curved 

 veins which are often found to fork, when examined with a magnifier, 

 just as in Taeniopteris densinervis Feistmantel (Jurassic Flora of Each, 

 pi. J I, fig. 6a). The specimen, however, is too meagre even for a 

 certain generic determination. Loc. — Ozo. 



9. Macrotaeniopteris Schimp. 



19. Macrotaeniopteris ef. Riehthofeni Schenk. 

 PL III, fig. 4, 5. 



Frond elongated, entire, acuminate at apex; secondary veins 

 numerous, dense, rising at acute angles at base and then becoming 

 horizontal towards the margin, simple or dichotomous. 



The two figures above cited represent two faces of the same leaf. 

 It is a fragment, belonging to the apical part which is long drawn 

 out. The specimen measures about '11 mm. in breadth near its 

 base, from which place it appears to taper downward. Therefore the 

 frond is not a large one such as is possessed by many of the species des- 

 cribed under this genus. The midrib is rather weak and gets weaker 

 towards the apex. The secondary veins are dense, many of which 

 furcating near the point of rising along the midrib, but many also 

 remaining simple for their whole length. Very rarely, forking takes
