A herbaceous perennial, with a wide-creeping rhizome. Stems 
half to one and a half foot high, ascending, angular, firm, sulcate, 
scabrous, usually with one head, rarely with two to four. Leaves 
aggregated upon the lower third of the stem, sessile, ascending, 
linear or lanceolate, two to four inches long, acute, distantly 
toothed, rigidly subcoriaceous, distinctly triplinerved, very rough 
on both sides, with raised points and short bristly hairs; upper 
half of stem with only two or three much reduced linear bract- 
like leaves. Involucre campanulate, composed of two or three 
rows of firm linear acuminate scabrous subequal phyllaries. 
Heads an inch and a half to two inches broad, all the florets her- 
maphrodite and perfect. Achenes gray, flattened, scabrous, 
margined with a distinct border. Disk-florets yellow; ray-florets 
twenty to thirty, purple. Pappus double, the brisiles of the outer 
row very minute, of the inner rigid, elongated, distinctly 
ciliated.

flower; 4, ray-flower; 5, its stigmas; 6, bristle of pappus: all

A somewhat peculiar and straggling species of Aster. It is 
treated as a cool greenhouse plant in my garden, but it will 
stand the climate of a mild winter in this country out of doors, 
as I have ascertained by occasionally leaving a plant or two in 
the open borders. I am indebted to Mr. Daniel Hanbury for my 
stock of this plant.—W. W. S.
