50 M. YOKOYAMA. 



Dr. Geyler established this species on a leaflet from the Tetori- 

 gawa-valley, which was 50 mm. long and 10 mm. broad, and pierced 

 with 14-16 fine veins. The only specimen which I could obtain of 

 this species is a leaflet from Okamigö, 32 mm. long and 10 mm. broad, 

 therefore somewhat shorter than the one figured by Geyler. It is 

 furnished with about 15 very faint delicate veins between which I 

 have often observed one or two extremely fine veinlets. Its form is lan- 

 ceolate with the broadest part near the base, and above gradually nar- 

 rowing into a rather acute apex. Podoz. cnsiformis Hr., with which 

 Geyler compares this species, has much slenderer leaflets pierced with 

 a somewhat less number of coarser veins. 



I may here advance my opinion concerning the fragmentary speci- 

 mens of a Podozamitcs identified with P. cnsiformis Hr. by Geyler (Foss. 

 Vflanzcn, p. 227, pi. XXXII, fig. 1). This author gives for his specimens 

 20-22 veins, whilst Heer's species possesses only 10-13 (Bcitr. 1876, 

 p. 46) ; and he rejects Zamites Sclimidtii Andr. from the Liassic flora 

 of Steierdorf for the very reason that the latter has 14-16 veins. 

 Here evidently Dr. Geyler is mistaken; and this mistake has been 

 noticed by Heer (Naclitr. p. 3) who considers the Japanese specimens 

 as referable to P. tcnuistriatus Gcyl. But, as already mentioned, they 

 possess 20-22 veins, whilst leaflets of P. tcnuistriatus have only 14-16, 

 only a little more than in P. cnsiformis. Therefore I think it most 

 proper to refer the specimens described by Dr. Geyler as P. cnsifor- 

 mis Hr. to P. lanccolatus var. gcnuina Hr., to which indeed his broken 

 leaflets show the greatest resemblance. Loc. — Okamigd.
