Low gumweed as seen at about 4000' along Road S1750 on the east side of King Mt, which is several miles south of Mt. Adams.........September 30, 2006. Note that the tips of each involucral bract are curved outwards then reflexed downward and the resinous covering to the bracts. Note the acute-tipped teeth on the leaf margins which help separate this from Grindelia squarrosa.
