~ Senecio Kingii sp. nov. 
Senecio eremophilus D. C. Eat., Bot. King’s Exp. 191. 1871. 
Not S. eremophilus Richards. 1823. 
Perennial, with a thick rootstock; stems glabrous, 3-6 dm. 
high, rather stout, leafy; leaves obovate or oblanceolate in out- 
line, 4-7 cm. long, the lower petioled, all pinnately lobed one 
third to one half the distance to the midrib, with ovate or lanceo- 
late, more or less toothed lobes; heads numerous, corymbose- 
paniculate, 9-11 mm. high; involucres glabrous, campanulate, 
7-8 mm. high, 6-7 mm. broad; bracts linear, acute, carinate, 
sometimes with small black tips; the calyculate ones few, subulate; 
rays 5-7 mm. long; achenes scabrous-papillose on the rounded 
angles. 
This species is related to S. eremophilus, but differs in the some- 
what smaller and erect heads, less deeply dissected leaves, and 
their broad and short divisions, and shorter rays. One of the - 
specimens cited below was determined some years ago as S. glauci- 
folius, but that species differs from this as well as from the rest 
of the group in the narrower and scarcely carinate bracts.
