Much like no. 1 [Galinsoga quadriradiata Ruiz & Pav.], less hairy, the stem glabrous or sparsely pubescent with appressed or sometimes spreading hairs, the peduncles appressed-hairy, or finely villous with spreading, gland-tipped hairs; lvs ovate or lance-ovate, mostly less coarsely toothed; outer invol bracts 2–4, scarious-margined, persistent, the inner ones and their attached pales also persistent; inner receptacular bracts deeply trifid; achenes sparsely appressed-hairy or glabrous; pappus scales of the disk-fls conspicuously fimbriate, generally blunt, nearly or quite as long as the cor; rays to 1.5(–2) mm, nearly or quite epappose; 2n=16. Native from sw. U.S. to S. Amer., but now a cosmopolitan weed.
