Thtbsanthema htbeidum. Tussilago hybrida, Linn.

 somewhat sinuate-lobed, the lobes retrorse, as are also the seve- 

 ral prominent teeth of each : scape usually one only, 8 to 12 

 inches high, slender, much dilated under the involucre, the 

 dilatation an inch long or more and white tomentulose ; involu- 

 cre an inch long ; bracts few, subulate to subulate-linear, the 

 margins flocculent ; achenes slender ; pappus slenderly stipitate.
