	Crepis capillaris	Crepis intermedia
	smooth hawksbeard	gray hawksbeard, intermediate hawksbeard, limestone hawksbeard
Habit	Branched annual, 1-9 dm. tall, often covered with short, stiff, pointed yellow hairs throughout, with milky juice.	Perennial with 1 or 2 stems from a tap-root, 2-7 dm. tall, more or less grey-woolly throughout, with milky juice.
Leaves	Basal leaves petiolate, the blade lanceolate to oblanceolate, with fine teeth to pinnatifid, 3-30 cm. long and 5-45 mm. wide; cauline leaves reduced upward, becoming sessile, narrowly lanceolate, clasping and auriculate.
