CYCADOPHYTA 



[CH. 



Bucklandia 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^ Ward expressed the opinion 



Fig. 576. Bucklandia Milleriana. Brora, Scotland. (Manchester Museum, 

 L. 7229. ca. ^ nat. size.) 



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

 now used to include Yatesia this combination is fortunately avoided. 

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