JURASSIC PLANTS FROM KAGA, HIDA, AND ECHIZEN. 47 



3, PI. V is 57 mm. by 105 mm. Fig. 7 and 9, PI. V, represent 

 leaflets which seem to have been longer when compared with the 

 above three, and are indeed the typical specimens of this variety, the 

 shorter ones representing what mri} 7 be considered as passage forms 

 between this and the succeeding group. Veins vary between 20 and 

 25 in number. 



e.) P. lanceolatus var. Eiehwaldi Heer. 



PI. IV, tig. In, 4b, c. PL V, fig. 2, 4, 5a, 1). c, 6. 



PI. XI, fig. 6.? 



Leaflets are more or less parallel-sided, with apex obtuse or 

 nearly rounded. 



As in Bureja, China and Spitzbergen, this is the most frequent 

 of all the varieties of P. lanceolatus occurring in Japan. The speci- 

 mens I have figured vary considerably in size and breadth, some being 

 much smaller and some much longer than others. Smaller forms are 

 represented in fig. 1, 4, PI. IV, and fig. 5, PI. V, of which the last 

 is perhaps the smallest that has as yet been figured, though not 

 completely preserved. Fig. 4, PI. V, is a broader form and corresponds 

 to the. typical figures of Heer (comp. Beitr. 1876, pi. XXVII, fig. 1). 

 So is fig. 6. Fig. 26, PI. V, seems to have been considerably longer 

 than others; but as it has the sides nearly parallel and the apex blunt, 

 it must be referred to this variety. A leaflet (PI. V, fig. 2a) which I 

 formerly considered as Podozamites imlcliellus Hr. (Bull. Geol. Sec. 

 Japan, B. Vol. I, p. 6) is probably an abnormal form of P. lanceolatus 

 Eiehwaldi, as it seems to have been furnished with a short stalk. So 

 is the leaflet from Ushimaru (PI. XI, fig. 6) with 25 veins and men- 

 tioned in the Bulletin as a new species. 



Found at Shmamura, OJcamigo, Tanimura and Uhimaru.
