Root perennial. Sle?n 2 to 3 feet high, branched, mostly hairy, especially at the 

 joints, and towards the summit, sometimes nearly smooth below, fistular (the var. 

 mollis, or oblongata, solid with pith). Leaves 2 to 3 or 4 inches long, and 3 fourths 

 of an inch to 2 inches wide, more or less ovate, serrate, hairy, punctate beneath ; 

 petioles half an inch to an inch long, piloseciliatc. Flowers on short pedicels, in 

 broad dense terminal heads (1 to near 2 inches in diameter), which are sometimes 

 proliferous; outer bracts lanceolate, or lance-ovate, acute, entire, or subdentate, 

 sessile, partially colored, purplish, or often greenish white ; iiiner bracts narrow', 

 sub linear, ciliate, with filiform points. Calyx about half an inch long, nearly 

 cylindric, slender, a little curved, striate, witli 5 acute teeth, hairy at the orifice. 

 Corolla varying from violet-purple to flesh colored, and greenish white, pubescent ; 

 upper lip linear, sub-falcate ; tube slender, exserted. Sla?nens 2, ascending, a lit' 

 tie exserted, the. filatnents enclosed in the upper lip of the corolla. Style exserted 

 unequally bifid at apex. 



Uab. Fence-rows; borders of thickets, &c. frequent. Fl July. /^.September. 

 Obs. This is a variable plant ; and Mr. Dentham has reduced several species, 

 of preceding Authors, into this one. Even the M. mollis, L. Pursh, &c. he consid- 

 ers as nothing more than a varicty,-znd I have not ventured, in opposition to such 

 high authority, to retain it as a distinct species : But I must say that it seems to 

 possess some striking and constant characters of its own. It is not so common as 

 the true M. fistulosa ; and I find the plant to be generally smaller and more hoary- 

 pubcscent,-the stem more slender, and constantly solid with pitb,-the leaves 

 narrower and more oblong,-thc heads of flowers more dense, more conspicuously
