Crepis pleurocarpa grows in dry, wooded or open habitat, sometimes on serpentine soils. It is a taprooted perennial herb producing a branching stem up to 60 centimeters (24 inches) in height. The mostly lance-shaped leaves are lobed and long near the base of the plant, approaching 30 centimeters (12 inches) in length, and smaller and sometimes unlobed farther up the stem. The inflorescence is an open array of many flower heads, each with pointed phyllaries with thick midribs and thinner, hair-lined edges. Each flower head has 5 to 8 golden yellow ray florets but no disc florets. The fruit is a narrow, ribbed achene with a whitish pappus.[4]
