toothed or 2-3-lol)ed, terminal one on the lower leaves often roundish and 
coarsely toothed ; heads many in a compound corymb ; involucres bell-shaped, 
almost ecalyculate; the scales glabrous, 12-15, 3" long; rays 7-12, 4-5" 
long ; achenia glabrous. — Forms with the leaves less incised approach S. 
aureus, and those with much incised leaves resemble S. multilobatus, but the 
plant is smaller, has fewer stems, and is almost always somewhat webby- 
tomentose. New Mexico, Utah and Nevada. Frequent from the West to 
the East Humboldt Mountains, Nevada, and in the Wahsatch and Uintas ; 
5-9,000 feet elevation ; May-August. (G74.) 
Senecio multilobatus, T. & G. PL Fendl. 109. ' 'Annual or biennial, 
[and probably sometimes perennial, webby pubescent but] very soon glabrous ; 
stems very many, a foot high, simple, coryml)osc at the summit ; leaves some- 
what fleshy, the primary ones spatulate, often entire ; later ones all pinnately 
9-21-parted; lower ones long-petioled, the uppermost sessile, tlic base 
scarcely or not at all auricidatc ; segments cuneate-ol)long, incisely toothed or 
2-3-lobed at the apex ; coryml) dense, the heads numerous ; involucre nearly 
ecalyculate, of 12-14 scales; rays 5-G, oblong; disk-flowers 20-30; achenia 
strigosely puberulent. — Abundant on the Uinta River, (Fremont.) Common 
on the foot-hills about Salt Lake City and in the lower caiions of the Wah- 
satch; also on Antelope Island; 4,500-6,000 feet elevation; June. The 
specimens collected were apparently perennial ; the rays are 7-8, and the 
achenia quite glabrous, and strongly striated lengthwise. The plant grows in 
dense clumps. (675.) 
Senecio filifolius, Nutt. Perennial, suffruticose, densely webby-

parted, the divisions 3-9, narrowly linear, G-15" long, 1" wide, the margins
