 foot high, and are garnifhed with winged leaves, 

 compofed of two pair of oval acute-pointed lobes, 

 and at the bafc of the foot-ftalk is fituated a ftipula, 

 (or fmall leaf,) Ihaped like the point of an arrow cut 

 through the middle. This embraces the ftalk. The 

 lobes of the leaves are about an inch and an half 

 long, and near an inch broad, ending in acute points.

The flowers ftand upon foot-ftalks, which anTefrorii 

 the wings of the ftalk ; they arc about tTiree iiiche^
