SENECIO PSEUDAUREUS.
Perennial from a creeping rootstock ; plant perfectly glabrous except the tips of the bracts; stem 5-8 dm. high ; basal leaves broadly ovate, somewhat cordate at the base, serrate, 4-7 cm. long, long-petioled ; stem leaves more or less laciniate at the base, the upper sessile ; inflorescence corymbose, flat-topped, of 8—'0 heads about 8 mm. high ; bracts linear ; rays orange, about 8 mm. long.
It most resembles S. aureus and represents it in the Rockies.
It has the same large basal leaves as that species, but they are less cordate at the base, not quite as wide and serrate instead of crenate. S. aureus is a strictly Eastern species.
