Larger than either of the preceding species, two to three feet high, the whole plant usually rough-hairy. Base leaves about six inches in length, oblong to spatulate, lobed or coarsely and very irregularly toothed, narrowing to margined petioles; upper ones much smaller, lance-shaped, and clasping. Heads deep yellow, more than an inch broad, in an open corymbose cluster; involucre about a half-inch high, its principal bracts narrowly lance-shaped, the outer row short, pointed, and spreading. Achenes smooth, slightly tapering to the apex, with thirteen ribs and a spreading pappus of very fine, white bristles.
Hoe-cutting or spudding of first year leaf-crowns from the fleshy root; plants that survive to form fruiting stalks in the second year should be cut close to the ground before the first flowers mature.
