Remarks. Schimper unites with this species Cyclopteris Hochstetteri, Ett.,* 

 but Stur in his Culm Flora treats them as distinct. The character on which 

 Stur seems to place considerable importance is the alternate pinnules in 

 C. Hochstetteri, and the opposite pinnules in C. polymorpha, Goppert. 



On both the figures of C. Hochstetteri given by Stur, the pinnules on the 

 lower portions of the fronds are opposite, but on the upper part they are 

 alternate. 



The alternate or opposite arrangement of pinnae or pinnules appears to be 

 a character of little value, as they are frequently alternate and opposite on 

 different parts of the same frond. 



The variety of C. polymorpha, named rotundifolia by Goppert, probably 

 represent* the lower portion of a frond, his type of the species being the
