This hasa great Root in refpect of the Plant, being more 
than an Inch long, woody, of a white brown colour, and 
firmly fix’d in the ground. From hence {pring two or three 
Stalks, two or three Inches long, having feveral Leaves exactly like thofe 
of Polygala vulgaris. ‘The Flowers are at top of the Brartches, yellow, and 
tetrapetalous, after which follows a {mall Pod. 
Ic grows in the claiy grounds inthe Town Savannas. 
This does not agree with the Title of Polygala S. flos Ambervalis Viginiana

to be no different Kind, but only a variety, and this variety in largenefs, 
in deeper waters, is taken notice of by Lobel in his Adverfaria. 
It is very good againft the Scurvy or Chronical Difeafes, it is Diuretick, 
and very opening, being made ufe of for many days together, in Sallads or
