“ Similar to A. divaricatus, stems red, tough 
“ Leaves chiefly ovate-lanceolate, not large, rough, thick, 
slender-petioled, coarsely serrate, pale, or dull, the apex incurved- 
acuminate, the upper spreading or deflexed, sessile by a broad 
base, lanceolate-triangular, serrulated. Inflorescence high, with 
percurrent axis, the long suberect branches each bearing a small 
umbelliform cluster of heads ; peduncles filiform, as long as the 
heads, 3"—4" long; bracts pale ; rays short, narrow, chiefly 6, 
snow-white ; disks at first golden-yellow, finally sienna-brown ; 
florets about 20 ; achenes [when young ; sometimes when mature] 
densely short- hairy. 
“In sunny or e shaded rocky places, New York to the 
mountains of Virginia. September.’ 
OTA remarks. Stem usually about 2 ft., without 
obvious hair, dull red or reddish-brown, tough, terete, erect but 
slightly sinuous above. 
Leaves about 314 x 2 in. or smaller, rather uniform, very 
slowly diminished ed often all are about 2 x I in. 
eaf-texture thick or thickish, compared with A. divaricatus 
L., strongly roughened when dry; often roughish when fresh, 
but as often smooth, even sometimes so when in the sun 
Leaf-form ovate-acute to ovate-lanceolate. Petioles short, 
slender, mostly less than half the leaf-breadth, finally forming a 
short concave wing, and usually disappearing with the axiles. 
Sinus strong, quite persistent, chiefly sharp; broad and deep 
in one or more lowest leaves, broad and shallow sometimes in one 
Or more upper ones, and then replaced by truncate or finally 
rounded bases. Teeth sharp, moderate in size, curvescent or with 
back of a single-curve, irregularly spaced. Apex incurved-acute 
or short acuminate. 
Axiles lanceolate-triangular, broad based, sessile or almost so, 
deflexed or spreading sharp-serrulate. Rameal similar but Mee 
denly and greatly reduced. Ramulars form little discules, 4} in. 
broad or less often none. 
Veins inconspicuous above, very slender and cord-like Beto 
forward-curved, chiefly 6 pairs, sparingly strigose-hairy.
