Stem glabrous, villous, or hirsute, paniculately 
branched, usually bushy, 1°-3° high, the branches 
racemose, and the branchlets often somewhat se- 
cund. Leaves firm or rigid, the basal ones spatu- 
late, obtuse, dentate, narrowed into margined peti- 
oles, glabrous or ciliate; stem leaves narrowly 
linear to linear-lanceolate, acute, entire, 1-3’ long, 
1-3” wide, those of the branches linear-subulate, 
numerous; heads usually very numerous, 4-7” 
broad; involucre campanulate to hemispheric, its 
bracts coriaceous, lanceolate or linear-lanceolate, 
abruptly acute or acuminate, green-tipped, imbri- 
cated in about 3 series; rays 15-25, white, or tinged 
with rose; pappus white; achenes finely pubescent.

A densely villous, broad-leaved relative or race of this species, ranging from Ohio to North 
Carolina and Michigan, is known as Aster ertcoides platyphyllus T. & G. 
This species apparently hybridizes with A. paniculatus Lam. where the two grow together.

Stem very slender, glabrous, simple, or with

bushy, 6’-2° high. Basal leaves lanceolate, oblong 
or oblanceolate, 2’-6’ long, 2’-6” wide, entire, or 
slightly toothed, ciliate and sometimes a little 
pubescent, at least on the slender petioles which 
are often as long as the blades; stem leaves nar- 
rowly linear, those of the branches small and sub- 
ulate; heads as large as those of A. ericoides, or 
commonly smaller, usually fewer, solitary at the \ 
ends of the branches and branchlets; bracts of 
the involucre with short green tips; rays white. 
On banks, especially in rocky places, Massachusetts 
and Vermont to Wisconsin. Aug.—Oct.

Stem pubescent, widely branched, 1°-23° high. Basal 
leaves oblanceolate, obtuse or acutish, entire, petioled, 
1’-3’ long, the petioles ciliate, broad; stem leaves linear- 
lanceolate, sessile, ciliate, acuminate, #’-2’ long, those 
of the branches similar but smaller; involucre nearly 
hemispheric, about 3” high, its bracts linear, the outer

broad; rays bright purple or pink.

Aster kentuckiénsis Britton, also of Kentucky and North 
Carolina, differs in being glabrous, its involucral bracts all 
gradually acuminate.
