Diagram XXIX. Bucklandia squamosa. Brongn. 



Unique specimen, on a slab of Stonesfield slate. The drawing, made of half size, 

 represents an interior axis with longitudinal furrows enclosing lanceolate spaces. 

 These appear to have furnished vascular bundles. Almost in contact with this axis 

 are the leaves or scales, seen externally in the upper part, and edgeways on the right 

 hand, where they suggest the idea of a twisted base and a longitudinal implantation. 

 They cannot, however, be traced to actual attachment. The apices of a few of the 

 scales or leaves have a rhomboidal cicatrix, or short furrows, and one or two small 

 oval prominences appear on the same or other scales. On the same specimen is a 

 leaf or fruit scale, 3-3 inches long, with an amygdaloidal end two inches long, having 

 rows of minute punctures. The leaves or scales on the stem are finely striated in 

 a longitudinal direction, without any sign of midrib. 



* The figure is given by Buckman, Geol. of Cheltenham, Plate I. fig. 3, under the 

 title of Cycadites.
