 incised in the middle : the dorsal margin arched near base ; 

 cells minute, orbicular, crowded, distinct at tips, larger and 

 clearer in body of leaf and base. Stipules free, close, quadrate, 

 sub-adpressed with the upper margin overlapping the stipule 

 above, and laciniate-toothed, the sides usually straight and
