These two species are considered by our Botanists now as mere varieties. 
I have, therefore, placed them together. 
Stem very variable in size, three to seven feet high, robust, very hairy, 
branching very profusely towards the summit. Lower leaves sessile, lan- 
ceolate, acute, very rugose, very scabrous on the upper surface, scabrous 
and hairy underneath, more or less coarsely serrate; upper leaves generally 
ovate, with a few serratures. Flowers in large almost corymbose panicles, 
composed of small recurved branches. Scales of the involucrum linear- 
lanceolate, nearly glabrous. Florets of the ray rather small. Seed pubes- 
cent. 
There are certainly some remarkable varieties included under this species; 
a few I shall enumerate. 
а . Rugosa. Muhl. Stem about three feet high, villous. Leaves finely 
serrate, less rugose than those of the other varieties. Flowers in a pyra- 
midal panicle. 
б. Stem hairy, rough. Leaves very rugose. Lateral branches of the pani- 
cle long, slender, slightly recurved. 
C . Stem and leaves similar to the last. Branches more robust, producing 
numerous recurved racemes; each branch forming a long cylindrical mass 
of flowers. 
d. Stem softly pubescent. Branches scattered, divaricate, recurved, nearly 
simple. 
Grows in damp rich soils. 
Flowers September — October. 
8. Villosa. Pursh. 
S. caule erecto, vil- 
loso; foliis sessilibus, 
oblongo - lanceolatis, 
subpilosis, enervibus, 
inferioribus serrulatis; 
racemis paniculatis, 
secundis. 
Pursh, 2. p. 538, Nutt. 2. p. 159. 
Stem three to five feet high, robust, villous, with many recurved expand- 
ing branches near the summit. Lower leaves oblong-lanceolate, serrulate, 
with a few long scattered hairs along the veins, slightly scabrous, particu- 
larly along the margins and midrib; the upper oval or ovate- lanceolate, very 
entire, with the axils generally crowded with small leaves. Flowers nume- 
Stem erect, villous; 
leaves sessile, oblong- 
lanceolate, somewhat 
hairy, nerveless, the 
lower serrulate; ra- 
cemes paniculate, se- 
cund.
