 rows, very minute at apex and margins, larger in centre and at 

 base, apparently compound, each being dark with an orbicular 

 light centre. Stipules free, quadrate, broadest at base, wider 

 than stem, recurved, much toothed on three sides ; teeth acute 

 and bi-cuspidate, each composed of 2 clear longitudinal cellules ;
