the proximal portions of the heavy and dense clump of attached 

 roots. Whether most of the wear preceded silicih'cation or not 

 must of course be largely a matter of conjecture. 



Stem. 



As will be seen from figs. 1 and 2, comparatively little of 

 the once large stem remains and, on the whole, the preservation 

 of the stem parts is not nearly so good as that of the roots.

The latter are in an almost perfect state of preservation, far 

 exceeding that of any fossil palm roots hitherto described. 

 This circumstance, together with the fact that fossil palm roots 

 have so rarely been found and have not been very fully de- 

 scribed, made a rather careful study of the anatomy of this 

 specimen seem worth while. 



In the following paper no attempt is made to review the 

 literature either on fossil palms or on the anatomy of palm 

 roots, as both subjects have been treated at length in recent 

 monographs. Stenzel* describes sixty- two species of fossil palm
