AFFINITIES OF CEPHALOTUS. 359 



length, and those forming the stratum or circle externally 

 bounding the wood and existing in the veins of the leaves, 

 no essential difference in structure will I believe be found. 

 In these points there is little resemblance between Nepenthes 

 and Cephalotus, in the internal structure of which last there 

 is nothing unusual. 



Between the parts of fructification of Nepenthes or 

 Cephalotus and Sarracenia, there is still less analogy, and it 

 is obviously unnecessary to compare in this respect any of 

 these genera with Dischidia.
