and TN descriptio 
** Basal leaves often not cordate, deeply incised ; those of the 
stem long-acuminate or even caudate, sharply serrate with large 
acute close teeth, some of which are suberect; chief bracts of the 
involucre acute. — On rocky banks, solitary or in small clusters, 
Maine to N. Y. and N. J." 
Radicals rare ; those seen are variable, sometimes suboval and 
crenate-serrate, sometimes oblong, sharp serrate and without sinus. 
Hair more developed than on most A. C/aytoni, on bract edges 
and pedicels, and on leaves beneath. 
Leaves quite uniform in size, often about 2 17 x 14 in; or all 
narrower, as 312 x I% in 
ays short, oblong ; clear white, remaining for some time acute 
at the strongly flattening apex 
Bracts bevelled, few lingual, some of them tapering and acutish. 
Resembles typical A. Claytozi in leaf-texture, smoothish, fresh, 
highly roughened when dry, with cord-like veins obscure above ; 
and in lower leaf-bases, with strong sinus. Upper ones or axiles 
less truncate, more petioled; truncate axiles are finally reached 
high up the inflorescence. Unlike A. C/aytoni, the shallow sinus 
form of leaf-base is here predominant, or at least throughout the 
middle stem. Like A. Claytoni in the fragrance of its glowing 
golden-yellow just-opened disk-flowers; which quickly become 
light sienna-brown. 
— Grows in close masses occasionally, along roads, in sun, or 
in thin woods; but is most characteristically developed when in 
little solitary clusters, projecting from rocky slopes or even from 
nearly vertical cliffs. Seems to take the place of A. Clayton 
more and more toward the north, as about L. Erie. Collected in 
flower, Au. 10 to Se. 10, W: N. Y. to N. Y. City; in prime the 
last ten days of August. All the W. N. Y. plants grew on shale, 
those from near N. Y. City on gneiss, schist or basalt. Examples:
