Leaves broadly linear, varying considerably in size and shape, 

 traversed by numerous parallel veins exhibiting dichotomous branch- 

 ing, more especially in the basal portion of the lamina, but occasion- 

 ally also in other parts of the leaf. In the longer leaves the veins 

 follow a straight course through the greater part of the lamina, but 

 in the shorter and obovate leaves the veins tend to diverge towards 

 the edges in the upper part of the lamina. The epidermal cells have 

 rectilinear walls. 



The Eussian fossils originally referred by Schmalhausen ■'• to 

 Bhiptozamites from strata which are said to be of Jurassic age, but 

 which have been more recently demonstrated by Zeiller f to be 

 Palgeozoic, are no doubt very closely allied to Noeggerathiopsis 

 hislopi. Bhiptozamites goepperti is recorded also from Eussian 

 Permian rocks by Schmalhausen, and the leaf figured in his pi. v., 

 fig. 6 I can hardly be specifically distinguished from the smaller 

 forms of Noeggerathiopsis hislopi from Vereeniging. Feistmantel § 

 and Zeiller || have both drawn attention to the resemblance between 

 Bhiptozamites and Corclaites, and there can be little doubt that 

 Schmalhausen's plant should be placed in the Cordaitege and regarded 

 as generally identical with Noeggerathiopsis or Corclaites. Arber • 

 has described imperfect leaves from Austraha which, as he observes, 

 are probably identical with the Eussian type ; he notes the close 

 resemblance between Bunbury's species N. hislopi and N. goepperti, 

 but prefers to retain both specific names.
