 annual, 1-2 ft. or more high. Stem terete below, angular above, 2-3 lin. 

 thick, branching, glabrous or slightly puberulous ; branches with narrow 

 wing-like angles. Leaves alternate on the stem and branches, opposite 

 only at the forkings of the flowering branches; petiole lJ-9 lin. long, 

 J-1 lin. broad, flat and thin, decurrent as angles on the stem and branches; 

 blade |-:3 J in. long, V-1 in. broad, lanceolate or on the flowering branches 

 sometimes linear, acute, cuneately tapering from below the middle into- 

 the petiole, irregularly serrate with smaller and larger teeth and with 

 a very prominent wing-like midrib beneath, thinly pubescent with 

 line ."Spreading hairs on both sides or nearly glabrous above. Stipules 

 reduced to glands. Flowering-branches forked or raceme -like, H-^ 

 in. long, ascending or spreading. Involucre sessile or very shortly 

 pedunculate, solitary in the forks or at the nodes and apex of the branches,. 

 1-1 J lin. in diam., cup-shaped, somewhat woolly-pubescent outside and 

 within, with 4 glands and a oblong or ovate-oblong lobes, more or less 

 toothed at the apex ; glands distinctly stalked, erect, transverse, about 

 i lin. in their greater diam., concave, entire, red or purple. Capsule 

 shortly exserted, erect, about J in. in diam. at the base, slightly 

 narrowing to the apex and about as long as broad, covered with long 

 soft spreading hairs ; styles 1-1 J lin. long, united for the greater part

 similar to broad-leaved forms of E. systyloides in habit and appearance ; 

 stems probably annually produced, 2-3 ft. high, herbaceous, somewhat 

 woody at the base, simple or sparingly branched below, usually divided 

 at the top into a forked or 3-rayed cyme, but sometimes undivided and 

 flowering at the upper nodes and as well as the cyme-branches more or
