Leaves larger, lanceolate to oblong-lanceolate, 
entire, thin, or membranous, acuminate at the 
apex, strongly auriculate-clasping at the base, 
roughish above, pubescent beneath, usually nar- 
rowed below the middle, sometimes 6’ long; heads 
usually numerous, 1’-2’ broad, panicled, or some- 
what racemose on the branches; bracts of the 
involucre lanceolate, glabrate, rather loose, with 
herbaceous tips; rays numerous, purple-blue. 
In woods and thickets, New York to Ohio, North 
Carolina and Tennessee. Perhaps a sylvan race of 
the preceding species. Aug.—Sept.

Stem stout, hispid pubescent, corymbosely 
branched above, 2°-8° high, very leafy. Leaves 
lanceolate, entire, rather thin, acute, pubescent, 
2’-5’ long, 6-12” wide, clasping the stem by an 
auriculate or broadly cordate base; heads nu- 
merous, I’-2’ broad, clustered at the ends of the 
branches; involucre hemispheric, its bracts linear- 
subulate, somewhat unequal, green, spreading, 
pubescent and more or less glandular, viscid; 
rays 40-50, linear, 5’-8” long, violet-purple, 
rarely pink or red, or white; achenes pubes-
