Palccozoic Species mentioned iii "Fossil Floral 349 



Remarks. — The above limited references to the synonymy 

 of this widely-distributed species gives an epitome of the 

 history of changes of opinion as to the afthiities and position 

 of this plant, changes mostly brought about by the discovery 

 of more perfect specimens. 



Grand' Eury was the first to point out that the wood of 

 certain stems, which from their external and internal char- 

 acters were shown to belong to Cordaites} was similar in 

 structure to the Pinites Brandlingi, Witham.^ 



Since this discovery the plant has been placed in the genus 

 Cordaioxylon as C. Brandlingii, and more recently Goppert 

 has described the wood simply as Cordaites Brandlingii.^ 



There is little reason to doubt the identity of Pinites 

 Brandlingi with the stem of Cordaites, and as showing more 

 clearly the true nature of the fossil, perhaps Goppert is quite 

 justified in the course he has taken. 



But this discovery in regard to Pinites Brandlingi raises 

 the whole question of the other Araucarioxylon species, and 

 it undoubtedly favours the opinion that they most probably 

 are also referable to Cordaites. In the other species of 

 Araucarioxylon, however, absolute proof of this is, I believe, 

 wanting.*
