484 CYCADOPHYTA [CH. 



BucJclandia Yatesii (Carruthers). 



This type from the Lower Greensand of Bedfordshire (fig. 577) 

 was described by Carruthers as Cycadeoidea Yatesii and subse- 

 quently named Yatesia Morrisii 1 , Ward expressed the opinion 



FIG. 576. BucJclandia Milleriana. Brora, Scotland. (Manchester Museum, 

 L. 7229. ca. % nat. size.) 



that the name should be Yatesia Yatesii, but as Bucldandia is 

 now used to include Yatesia this combination is fortunately avoided. 

 The stem is cylindrical, 20 30 cm. long and 12 cm. in diameter,
