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. Stigma small, 

 club-shaped and undivided, by which it essentially differs from 

 E. montanum, and agrees with tetragunum hereafter described. 

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

 mule production. 



6. E. telragonum. Square-stalked Willow-herb. 



Leaves lanceolate, sessile, minutely toothed. Stem erect, 

 unequally quadrangular. Stigma undivided.

In ditches, and watery marshy places, common. 



Perennial. July. 



Root somewhat creeping. Herb nearly or quite smooth. Stem 

 erect, 12 or 18 inches high, seldom a little downy, roundish, 

 with 4 angular ribs at unequal distances. Leaves for the most 

 part alternate, generally sessile, much narrower than the last, 

 minutely and unequally toothed. Fl. few, in leafy clusters. Pet. 

 pale purple, cloven. Stigma ovate, or club-shaped, always un*- 

 divided. Caps, and JLower-stalks a little hoary.— Mr. Curtis 

 thought E. roseum a variety of the present species ; but from 

 long observation I am now persuaded they are permanently di- 

 stinct.
