phyll in T. In the lower epidermis each cell bears a papilla (T.) ; 

 only a few slight papillae present (D.). Stomata in the plane of 

 the epidermis (T.) ; stomata raised (D.). The structure of the 

 upper part of the petiole is not very different in the two species, 

 but there is a considerable difference in the basal region. In the 

 stem the pitted vessels of the wood have spiral thickenings (T 

 no spiral thickening (D.). 



"All the points of difference enumerated above are comparatively 

 unimportant, and are such as are often found within the limits of 

 a single genus. Hence the investigation of the anatomy confirms 

 the close relationship of Tricuspidaria and Dubouzetia, while 

 leaving undecided the question as to whether the two genera 

 should be united or kept separate."
