4. E. watsonii Barbey. Plants 1% ft. high, tomentose-pubescent through- 

 out ; leaves elliptical, denticulate, rounded to short-winged petioles ; flowers

 branched above, 1% to 5 ft. high or more; glabrous below, more or less glandu- 

 lar above; leaves lanceolate, mostly alternate, with smaller ones fascicled in the 

 axils, sharply but minutely denticulate, mostly veined, iy± to 2 in. long; flowers 

 few. terminating the almost filiform spreading and nearly leafless branches, 

 the bracts almost subulate; petals deeply 2-cleft into linear-oblong lobes, rotate- 

 spreading, rose-purple, 3 to 4 lines long; capsule pediceled, about 1 in. long, 

 sharply 4-angled and acuminately beaked; seeds % to 1 line long. 



Dry ground, everywhere common. July-Oct. 



8. E. angustifolium L. Fire- weed. Stems erect, mostly simple from a 

 stout root, 2 to 5 ft. high, glabrate below r , the inflorescence canescent; leaves
