Stem simple, from an annual root, 3-4 dm. high, woolly, often 

 slightly yellowish ; leaves linear, or the lower oblong-spatulate, 

 white-wooll}'' with rather appressed pubescence, mostly erect and 

 close to the stem; heads in a small glomerate cyme, about 5 mm. 

 high and 4 mm. in diameter; involucre woolly at the base, otherwise 

 glabrous, shining and yellowish; achenes oblong, obtusely angled, 

 glabrous ; pappus straw-colored, falling off separately. 



Differs from G. Chilense Spreng. {^G. Sprengelii Hook. & Arn.) 

 in the simple stem, smaller size, small and dense flower-cluster, and 

 yellowish involucre. It resembles G. liiteo-albitm of Europe, which 

 differs in the scabrous achenes.
