Aster patens var. phlogifolius Nees, Gen. & Sp. Ast. 49. 1832.

Similar to the preceding species, usually taller. 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 narrowed below the middle, sometimes 6' long; heads usually numerous, 1'-2' broad, panicled, or somewhat 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.
