few, very distant, serrate teeth, the upper surface supplied with 
numerous, irregularly disposed cystoliths which are distinctly 
visible to the naked eye, the lower surface somewhat paler, with- 
out cystoliths, smooth, the midrib conspicuous, the lateral nerves 
about 7 on each side of the midrib, slender, obsolete on the upper 
surface, not prominent on the lower surface, arched-anastomos-
