XXXIIl] CORDAITES 245 



Hislopi, may belong to that species. Zeiller and others definitely 

 assigned the Russian leaves to Cordaites. 



Euryphyllum. The Indian leaves for which Feistmantel 1 

 proposed this name are, as several writers have pointed out, in 

 all probability referable to Cordaites. 



The general conclusion to be drawn from this imperfect 

 summary of an extensive literature is that the employment of 

 the generic names Noeggerathiopsis, Rhiptozamites, Euryphyllum, 

 and others has tended to exaggerate the difference between the 

 European and Southern botanical provinces during the Permo- 

 Carboniferous period. 



Scale-leaves, seeds, and stems. 



The occurrence of small scale-like leaves of the type represented 

 in fig. 468,0, in association wiihCordaites (Noeggerathiopsis) Hislopi 2 

 in India, Brazil, Siberia, and elsewhere may mean that these 

 organs are scales of large foliar buds. The occurrence of several 

 forms of platyspermic seeds, in some cases apparently identical 

 with European forms and sometimes distinct types, in close 

 association with Cordaites (Noeggerathiopsis) Hislopi has already 

 been mentioned. Examples of such seeds are described in 

 Chapter xxxv. under the genus Samaropsis. 



There are very few satisfactory examples of Cordaitean branches 

 from the southern hemisphere. Schmalhausen 3 figures good 

 specimens from Siberian rocks from which his Rhiptozamites 

 leaves were obtained. Branches with spirally disposed leaf-scars 

 figured by Zeiller 4 from the Rhaetic of Tonkin closely resemble 

 Cordaicladus. Feistmantel's drawing of a fossil from the Kar- 

 harbari series, compared by him with a Fern rhizome 5 , may be 

 a Cordaitean branch, and the same author describes a stem 6 

 from New South Wales as Caulopteris Adamsi which bears a close 

 resemblance to a branch of Cordaites. Similarly a leafy shoot 

 described from India by Zeiller as Araucarites Oldhami 7 may be 

 compared with branches of the Poa-Cordaites type.
