Glebionis coronaria, native to the Mediterranean countries, has become established in coastal and low-elevation regions of south and central California, and a few scattered places in Arizona. Stems branch several times towards the top, and bear alternate, hairless leaves at closely-spaced intervals. The leaves are divided into narrow, strap-shaped lobes, pointed at the tip, and with a few teeth along the margins.
The relatively large flowerheads are solitary or in groups of up to three; they have a hemispheric involucre lined by several rows of broad phyllaries, the lower of which are green, the upper ones whitish, and thinner. The yellow ray florets (sometimes white towards the tips) are up to one inch long, and number from ten to 20; disc florets from 60 to over 140.
