Root tuberous. Stem two to four feet high, simple, glabrous ; lower leaves 

 very narrow or Hnear; glabrous, though a little hairy near thebase, crowded, 

 and frequently, as has been remarked by Mr. Nuttall, resembling tufts of the 



!f ^ *^*pi^ ^'^'^ ^'""^ palustris, upper leaves very small, setaceous, scatter- 

 ed. Howers crowded in a terminal raceme. Peduncle four to six lines 

 long, furnished with two or three small scales. Involucrum oblong, con- 

 taming about five flowers. Scales oval, membranaceous along the margin. 

 Corolla bright purple, sprinkled with glandular dots. Seeds furrowed, 

 very hairy. Pappus feathered, not coloured. 



I have specimens from the western districts of Georgia, in which the 

 lower scales of the involucrum are lanceolate, acute; the interior all emar- 

 ginate and sometimes lacerate; in all other respects agreeing exactly with 

 this species. I have always been accustomed to consider this plant as the 



L. Graminifolia, of Willdenow and Muhlenburg. though not of Walter and 

 Pursh. 



Grows in dry pine barrens. 

 Flowers, August — October.
