33. Podozamites sp. 

 PL XII, fig. 12. 



This is an imperfect specimen which is wanting both at apex and 

 base. It is attached to a stone in a curved state. It is 3 mm. broad, 

 and may have been long drawn out at apex. Veins are distinct, 

 about 8 in number with a finer one between. 



The leaflet is probably referable to Podozamites, and indeed I 

 mentioned it in the Bulletin as a new species. But now I consider it 

 better to be designated with a simple name of Podozamites sp., as the 

 specimen is not complete enough for exact determination. 



Loc. — Ohamigo. 



34. Podozamites sp. 

 PL VII, fig. 9. 



A leaflet longly elliptical in form, obtuse at apex, nearly sessile 

 at base, and furnished with 12 rather distant parallel veins. It meas- 

 ures 30 mm. long and 12 mm. in breadth, and resembles much the 

 narrower forms of P. pulchellus Heer (Beitr. z. foss. Flora Spitzb., p. 

 38, pi. IX, fig. 10—14), from which however our specimen seems to 

 differ in possessing 5-10 very fine dense interstitial veins. Whether 

 Heer' s species may have so many veinlets as in ours is a question 

 which can only be settled after the discovery of a much greater num- 

 ber of specimens. Loc. — Simamura.

u Leaflets many-veined, subauriculate at base; veins dicholomous, reti- 

 culated." (Oldham.) 



Oldham and Morris had described in their Rajmahal Flora a very 

 interesting plant which then accorded most with the genus Diclyopteris 

 Gutbier of the Carboniferous System, and therefore called by them
