to a true Cordaites, and as distinct from the members of the 

 Glossopteris flora described here, which, however, they closely 

 resemble in several respects. Kurtz ' has recently drawn attention 

 to the more spreading type of nervation in the leaves occurring in 

 the rocks of Gondwanaland. 



Zeiller 2 has pointed out that the constant occurrence of Cordaitean 

 seeds of the genera Cardiocarpus or Cordaiearpus in association 

 with N, JJislopi is an additional argument in favour of referring 

 Noeggeraihiopsis to the Cordaitales. 



On the whole, there seems to be a consensus of opinion at the 

 present time that Noeggeraihiopsis is probably best regarded as 

 distinct from Cordaites, although closely allied to that genus. 

 It is quite possible that the future may somewhat modify this view, 

 as our knowledge of the genus is still very imperfect, little or 

 nothing being known as to the habit of the plant, and there is an 

 entire absence of any evidence as to the fructification.
