slightly larger, but this is, perhaps, of little importance, as 

 exact measurements are, in most cases, difficult to make. 



The precise value of these agreements and differences, 

 from the systematists' point of view, is not easy to estimate, 

 but we cannot be far wrong in regarding the former as of 

 much greater value than the latter. To us, they seem 

 sufficient to justify the inclusion of the new spike in the 

 genus Calamostachys, which, as at present understood, is to 

 some extent, a collective one. Acting upon this opinion, 

 we propose that henceforth the fossil should be known as 

 Calamostachys Oldhamia.
