Burke: Packera breweri vs. Packera pseudaurea

	Packera breweri	Packera pseudaurea
		streambank butterweed
Habit		Fibrous-rooted perennial from a short rhizome, essentially glabrous by flowering time, 3-7 dm. tall.
Leaves		Leaves thin, the basal ones long-petiolate, the blades sharply toothed, ovate, cordate to truncate at the base, the cauline ones few, progressively reduced upward, becoming sessile, pinnatifid or incised toward their bases.
Flowers		Heads several to many, the disk 8-13 mm. wide; involucre 5-8 mm. high; rays 6-10 mm. long, yellow.
