Native in the far West, and rarely adventive. Collected in 1929 in River Rouge Park, Wayne Co.
The phyllaries and inflorescences are stalked-glandular, and the plant smells of tar. It is a slender, nondescript, glandular-pubescent annual with lower leaves opposite and the upper ones alternate. Apparently a waif in Michigan, but recently collected along a roadside in Ontario just N of Lake Superior, so to be expected in Michigan again.
