Perennial. July. 



Root fibrous. Herbage not unlike the last, but the stem is more 

 branched, and at the upper part obscurely quadrangular. Leaves 

 smooth, thin and delicate ; the upper ones alternate. FL paler 

 than the preceding ; petals streaked at the base. Sdgyna small, 

 club-shaped and undivided, by which it esseptially difl'ers from

 Yet it is too abundantly propagated by seed to be supposed a 

 mule production.
