Lower Oolite types ; these are referred to later under the genera 

 Baiera and Podozamites. 



CHINA. 



Among the Mesozoic plants recorded from China there are some 

 species which appear to be identical with Lower Oolite forms. 

 Our knowledge of the fossil flora of China is based chiefly on the 

 work of Newberry, 1 Brongniart, 2 and Schenk. 8 

 Podozamites lanceolatus (L. & H.) = ? P. laneeolatus (L. & H.). 

 Pterozamites sinensis, Newb. ; cf. Williamsonia pecten (L. & H.).

JAPAN. 



Geyler, 5 Nathorst,' and Yokoyama 7 have described several 

 species of Mesozoic plants from Japan, some of which appear to 

 be of Wealden age, 8 while others from Central Japan indicate an 

 Inferior Oolite flora similar to that of East Yorkshire. 



Licksonia nephrocarpa, Bunb. (small fragments) = ? Coniopteris hymenophylloides 



(Brongn.). 

 Pecopteris exilis, Phill. ; cf. Coniopteris arguta (L. & H.) and Klukia exili*
