Since the publication of my paper in which the genus Bcnstedtia 

 was suggested, Professor Fliche, of Nancy, has described some casts 

 of stems from the Lower Cretaceous of France under the name 

 Conifcrocaidon.''- The fossils are, I believe, identical with those 

 referred to Bcnstedtia. Professor Fliche draws attention to the 

 resemblance as regards surface features to stems of Araucaria of the 

 section Colyinhcea, but does not suggest a comparison with Zamia. 

 Without anatomical evidence it is impossible to say whether the 

 fossil stems are cycadean or coniferous, but the resemblance to 

 Zamia is at least as striking as their similarity to Araucaria, and 

 in case of doubt a non-committed term such as Bcnstedtia is 

 preferable.

The Uitenhage specimens referred to this genus are very similar 

 to those previously figured from Maidstone t and from the Sussex 

 coast. I They include partially flattened cylindrical casts, with 

 occasional branch-scars, and portions of much broader stems like 

 that represented in fig. 2, pi. v. 



The collection of Uitenhage plants in the Museum of the 

 Geological Society contains a few imperfect specimens like that 

 shown in fig. 2, pi. v., which Tate identified as probably cycadean.^ 

 I agree with his determination, and, while admitting the absence of 

 proof, am disposed to consider the specimens as casts of some 

 cycadean plant. The frequent association of these stems with the 

 fronds of Zamitcs recta is a point in favour of the supposition that 

 they represent portions of the same plant ; possibly the large Cyca- 

 dolepis scale-leaves may also have been borne on Bcnstedtia stems. 

 This is, however, merely a suggestion, in support of which I am 

 unable to furnish anything of the nature of proof.
