slender, the limb 5-lobed. Anthers obtuse and entire at the base, nearly or quite separate.

very plumose bristles. [Named for Dr. Adam Kuhn, of Philadelphia, a pupil of Linnaeus.]

Erect, puberulent and resinous, 1°-3° high, 
branched above. Leaves lanceolate or linear- 
lanceolate, acute or obtusish at the apex, nar- 
rowed at the base, sparingly dentate, or entire,

of the involucre lanceolate or ovate-lanceo- 
late, acuminate, the inner much longer, linear, 
cuspidate; pappus tawny, or sometimes nearly 
white. 
In dry soil, New Jersey to Georgia, Ohio, Min-
