Senecio Macounii, Grreene, Pittonia, Vol. III., p. 169. 



Tufted and apparently somewhat stoloniferous perennial, 

 the slender, nearly naked stems about a foot high, simple, 

 subcorymbose at summit, leafy below, lloccose-tomentose 

 throughout; leaves chiefly at and near the base of the 

 stem, hoary-tomentose beneath, more deciduously so 

 above, 3 to 6 lines long, including the slender petiole, this 

 much longer than the obovate or oblong-lanceolate or 

 oblanceolate blade, which is S-nerved and with variously 

 crenate, or dentate or repand-denticulate margin ; heads 

 small (as in S. Fendleri), in a rather compact cymose 

 corymb ; bracts of the involucre about 12 or 15, lanceolate, 

 thinnish ; rays as many, yellow ; achenes light colored, 

 5-angled, with 5 intervening striae ; pappus fine and soft.

 Distributed as S. lur/ens, var. exaltahis, Gray. 



Senecio Columbianus, Greene, Pittonia, Vol. III., p. 169. 



Taller and stouter than ^S*. lugens, often 3 feet high, the 

 stems solitary, not clustered, and without a root stock, but 

 proceeding from a not at all deep-seated fascicle of fibrous 

 roots ; leaves scattered up and down the lower half of the 

 stem (not clustered at base of a nearly naked stem) ; 

 pubescence scanty, curled-hairy rather than fine and 

 lanate or tomentose; heads three or four times as large as 

 in S. lugens, more than twice as numerous, and the corymb 

 compound ; bracts of the involucre more thick and fleshy, 

 scarcely black-tipped ; mature achenes light-colored, 

 scarcely angled or even striate.
