412 Mr Lillie, On Petrified Plant Remain.s, etc. 



A large number of them have been isolated from the matrix 

 and sections cut from them. The greater number of the specimens 

 consist of decorticated stems of Cordadtes, showing the pith and 

 the secondar}^ wood. This genus appears to be particularly 

 abundant in this locality. In addition to Cordaites, at least one 

 example of a new member, either of the same or an allied genus, 

 has been obtained. The attribution of most of the plants to the 

 genus Cordaites is borne out by the fact that examples of the 

 characteristic pith casts, Sternbergia (Artesia), of this genus also 

 occur in the conglomerate. In addition, a specimen of a well 

 preserved Myeloxylon, the petiole of a Medullosa, has also been 

 obtained. A contribution on the detailed structure of these 

 fossils is in progress.
