“Stem stout, 2—3 ft. high, with long internodes. Basal leaves 
often in extensive colonies, thin, dull green, firm, rough above, 
with scattered slender appressed bristles, pubescent beneath on the 
veins, reniform-cordate or cordate-triangular, often 7 in. long by 
5 in. wide, the basal sinus when well developed rectangular, 2 in. 
across and 1 in. deep. Upper leaves ovate-oblong to lanceolate, 
with a short broad basal wing, or sessile. Petioles of the lower 
leaves long, conspicuously ciliate when young [in certain forms]. 
Inflorescence decompound, flattish, or irregularly convex, 6 to 12 
in. broad; heads about 5 lines high; bracts greenish, mostly 
obtuse, tips and midrib dark-green, ciliate; rays usually 10. — 
In borders of woods and along fence-rows in partial shade, N. Y. 
to Mich. and Va. July-Aug." 
Stem greenish or brown, nearly smooth. Radicals chiefly 3, 
thickish and firm, thicker than in preceding ; thinner than the similar 
radicals of A. macrophyllus, and roughish above with flatter ap- 
pressed pale remote bristles. Rootstocks brownish, strong but not 
very much thickened. Primordial rather large and persistent, sub- 
orbicular, 2 in. across, with long pendant lobes and narrow sinus. 
Leaf-form reniform-cordate or deltoid. Sinus typically broader 
than in the last, closed by overlapping in growth, when flattened 
showing one straight line across within, and forming an oblong 
figure, not polygonal as in A. /imicola. 
Middle caulines still subreniform or deltoid, the sinus becoming 
broad, shallow and irregular. Upper caulines ovate-acute without 
sinus, with slender petiole. Axiles ovate-oblong, slightly tapered 
at the sessile or winged base ; the upper axiles lanceolate, usually 
with short wing. Rameals also often all short-winged, short and 
oblong-ovate. Pubescence strong on veins beneath, almost lack- 
ing elsewhere. 
Inflorescence a very irregular broad corymb of several sharply 
ascending branches different in length and rising therefore to vari- 
ous heights. Some lateral patentee often surpassing the inner, 
but all nearly simultaneous in flowe 
Heads about ~% in. high, or Sahib pappus, sometimes 45; 
in.; rays chiefly 10, fis arog 8 or 12, shorter, broader and less 
tapering than in A. curvescen 
Bracts greenish, ciliate, GRUPO TENE with prolonged green 
tips, obtuse, only the innermost essentially more pale or narrow.
