Hieracium greenei is a small, inconspicuous species found in the mountains of north California and (less commonly) south Oregon. The broad, greyish green leaves have quite a dense covering of long white hairs, on both sides, while the stem is coated by rough, tomentose hairs, plus a few of the longer hairs. Leaves grow only at the base.
Plants branch at or near the ground, sending up stems about one foot tall, topped by one or several flowerheads. The involucre is narrow and cylindrical, half an inch in length and enclosed by several rows of differently-sized phyllaries, with blunt-pointed tips. Flowerheads have between 4 and 10 yellow, ray-like florets (ligules), which have four notches at the tip and a style/stamen protruding from the base.
