790 MR ROBERT KIDSTON ON THE FOSSIL PLANTS OF 



fine close lines, and shows the true outer surface of the stem, as proved by the cetaceous 

 single nerved leaves being still attached to the uppermost and second nodes. The ribbed 

 stem of the example figured by Weiss I am inclined to ascribe to its condition of 

 preservation. 



The specimen given on Plate V. fig. 44 is not quite so well preserved, but shows faint 

 indications of the ribbing described by Weiss. The straight parallel lines seen passing 

 over the scar and other parts of the surface of this specimen must not, however, be 

 mistaken for ribbing, as they have been imparted to the stem by longitudinal cracks in 

 the coaly matter which once adhered to it. 



Stur * has united C. discifer, Weiss, C. pauciramis, Weiss, and C. macrodiscus y 

 Weiss, to C. Germarianus, Gopp.,t but [ do not think we are at present justified in 

 uniting all these species under one name.
