Nutt. 2. p. l6l. 
Stem erect, robust, three to five feet high, striate, pubescent. Leaves , 
except the lowest, sessile, lanceolate, serrate towards the summit; slightly 
pubescent on the upper surface, very pubescent underneath. Flowers large, 
in compound erect racemes. Involucrum imbricate, the scales linear, re- 
flexed like those of the Aster. Florets of the ray about ten, scarcely longer 
than the involucrum; of the disk sixteen to twenty. Seeds glabrous. Pap- 
pus hairy, scabrous. 
I have described the southern species, on which this name was first im- 
posed by Dr. Muhlenberg. It appears to differ in some though not very 
important characters, from the northern plant described by Mr. Nutt- 
all. It is one of our most ornamental species; it has the structure of an 
Aster, with the appearance and peculiar fragrance of a Solidago. 
Grows in dry sandy soils. 
Flowers in September.

S. caule erecto, gla-

Stem erect, gla- 
brous; leaves subulate, 
nearly linear, entire, 
glabrous, racemes e- 
rect, paniculate; florets 
of the ray middle sized. 
Stem two to three feet high, very glabrous, generally coloured, with many 
slender, erect branches near the summit. Leaves sessile, subulate, some- 
times lanceolate linear, acute, those of the stem very entire, very glabrous, 
though slightly scabrous along the margins, the upper axils frequently bear-
