Older Herbaria db these representatives : 
Herb. Linnaeus, in London, a leafy inflorescence of 4. divaricatus. 
Herb. Nees, fide specimen of Nees's certification, cultivated in Hort. Breslau ; 
given by Nees to Schultz Bipontinus, and in 1885 by Klatt to A. Gray ; now in hb. Cam- 
bridge Bot. Gar. Otherspecimens from hb. Nees represent vars. cymulosus and deltoideus.

the base of the one plant, all purplish at their ascending tips 
Puberulence moderate on midribs and principal veins beneath, 
increased to a minute tomentum over the pedicels, but little devel- 
oped over the involucre. Strigose hairs very slightly developed 
on the upper surfaces, most prominent as a ciliation upon bract- 
margins. Puberulence sometimes viscid when fast-growing in 
early summer ; but no true glandular or capitate hairs present. 
Radicals usually not developed except as small transient ovate- 
lanceolate basal leaves with much purple beneath, soon perishing. 
Walking daily for ten years in Central Park among thousands of 
plants more or less closely typical, no persistent radicals were seen. 
When developed these are usually few, small and inconspicuous, 
hardly raised into the light, glabrate, purplish-tinged, orbicular- 
acute, finely serrulate. More strongly developed persistent radicals 
have been observed in dry rock-clefts, in dry woods, among dead 
leaves of beeches (Ct. ; vic. N. Y.; and W. N. Y.), and also under 
hemlocks, a less usual habitat. They suggest the resource of slow 
growth, holding over in spite of unfavorable conditions. They are 
very thin, glabrate, cordate-oval, acutish or sometimes obtuse, 
2 x Id in. or rarely more, with broad, open sinus, about 5-7 
coarse sharp teeth on each side which project forward and are com- 
monly crenate or at least dorsally convex and elongated, much as 
in A. macrophyllus, and unlike the subsequent cauline leaves of A. 
divaricatus. They suggest that the common original for the two 
species had a strong crenate tendency. When most developed 
(beechen hills of W. N. Y.) such radicals form a rosette of 6—9 
dark nearly prostrate uniform leaves with very slender glabrous 
amc of nearly their own length. 
b commonly about 6 in. broad and 6 in. high; but 
cine twice this. Pedicels often 1 in. high. 
Heads round-topped in bud, on account of the obtuse bracts ; 
"eps of 4. MOMS tyllus are sharp-conical on account of acute 
racts.
