Porophyllum scoparium has limited distribution in southern New Mexico and west Texas, in counties adjoining the Rio Grande; it is more widespread in Mexico. Plants are small shrubs, producing many stiff, slender, gray-green stems, bearing narrow, linear, thread-like leaves.
Flowerheads, solitary at the branch tips, have narrow, cylindrical or slightly bell-shaped involucres, lined by seven to ten phyllaries, linear in shape, with blunt tips. Phyllaries are green, often reddish towards the tip. Each phyllary is marked with a pair of linear, reddish oil glands, above the midpoint. Flowerheads contain disc florets only, from 40 to over 80, all-yellow.
