Burke: Crepis capillaris vs. Crepis bursifolia

	Crepis capillaris	Crepis bursifolia
	smooth hawksbeard
Habit	Branched annual, 1-9 dm. tall, often covered with short, stiff, pointed yellow hairs 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.
Flowers	Heads several or numerous, 20-60 flowered; involucre 5-8 mm. high, its inner bracts 8-16, white-woolly and often glandular-bristly with black hairs, becoming spongy-thickened on the back; outer bracts linear, less than half as long as the inner.
Fruits	Achenes tawny, 1.5-2.5 mm. long, tapered at both ends.

Flowering time	May-November
Habitat	Roadsides, fields, ditches, wastelots, and other disturbed, open areas at low elevation.
Distribution	Occurring chiefly west of the Cascades crest and east in the Columbia River Gorge in Washington; Alaska to California, east across most of North America to the Atlantic Coast. [WildflowerSearch map] [BONAP county map]	[BONAP county map]
