42 ART. 8. — H. YABE. 



The first of them consists of two obcuneate pinnules, in 

 contact, borne on a stipe ; the pinnules bear no median vein, but 

 are traversed by spreading anastomosing veins. The second is a 

 linear pinna, apically cleft into two symmetrical lobes, with a 

 median vein. Its lateral veins are very fine, anastomosing, leaving 

 the median vein at an acute angle. 



Though at first the writer took the latter type as specifically 

 identical with S. Phillipsii var. major, the bilobed nature of the 

 pinnules of the Korean plant led him at last to regard it as a 

 different species. Such being the case, he believes it best to treat 

 the two types of the Korean examples as a single species, but 

 calling them for distinction, var. cuneata and var. major directly 

 after the example of S. Phillipsii. 



Another point of distinction of some value between S. Phillipsii 

 and S. hilobaia is found in the outline ef the pinnules which are 

 lanceolate in the former and linear in the latter. 



Another allied species which merits mention is S. tasmanica 

 Feistmantel^^ from the Carbonaceous beds (upper Mesozoic) of 

 the Jerusalem basin, Tasmania. The species was founded by 

 Feistmantel on a single example which shows a portion of two 

 lobes of a three-lobed frond as he understood it. Each lobe is 

 linear, attenuated above and provided with a median vein, quite 

 distinct in the greater part of the length though disappearing in 

 the apical portion, and with lateral, veins passing out from the 

 median vein at an acute angle and forming a single anastomosis. 



A comparison of this species with the Korean is rendered, 

 however, almost impossible so far as the outline is concerned,
