PLATE XV. 



" Pseudo-Bamboo Calamite." 



[Calamites pseudo hamhusia, of Sternberg. 



Suckovii, of Brongniart, Hist. Foss. Veg. tab. 14.) 



" This fossil was found in the clay which fills the fissures of a very fine grit, called by the 

 workmen ' Delf,' that forms a stratum from twenty to twenty-five feet thick, in the quarry 

 at Leabrook, near Wentworth, in Yorkshire. Immediately under this stratum there is a thin 

 bed of very good coal ; and at a considerable depth below this bed, there is a second layer of 

 coal, eight feet thick, which is covered in particular places with immense masses of fossil plants." 



The species here figured very closely resembles the Bamboos. The stem is arborescent, and 

 marked with parallel linear strife, which are intercepted at the sutures ; it is simple and cylin- 

 drical, and contracted at the articulations ; it occurs five feet or more in length. 



Fig. 1, represents part of the middle of a stem. 



Fig. 3, shows the gradual upward diminution of the stem, and its pointed termination.
