glabrous. Root-leaves 3 to 6, occasionally more, erect on very 
slender petioles 4’ to 8’ long, the blade 114’ to 3’ in length by 1%’ 
to 114’ in breadth, lance-oblong, acute or obtusish, the base short- 
cuneate to sub-cordate, sharply and unequally serrate; the cauline 
sessile and partly clasping, but some apparently petioled by the 
intervention of a more or less long, naked portion of the mid-rib, 
serrate above, below laciniate toothed, to distantly lacinately lobed. 
Heads mostly 8 to 12, on long, sometimes very long, slender 
peduncles, 3¢’ high; scales lance-linear acutish two-thirds as long 
as the disk-flowers ; akenes linear-oblong, sharply ribbed. 
Occurring in wet meadows and bogs along the border of woods 
or in otherwise partly shaded situations, Northern New England, 
New York, also in North Carolina. Collected by Robbins at 
Brownington, Vt.; T. G. White at Franconia, N. H.; Mrs. Clark 
and Dr. Britton, near Mt. Marcy, in the Adirondacks; Rusby and 
others at Willoughby, Vt.; and by Messrs. Small and Heller on 
Roan Mountain, North Carolina. 
It is a little strange that this fine species of Senecio has so long 
escaped publication asa species. It is probably due to the fact 
that the comparatively few botanists of the past generation who 
have dared say what they thought, never saw it in a growing state. 
In the herbarium it is not difficult to mistake it for S. aureus, but 
not so when seen growing. During the past season it was almost 
simultaneously discovered by Dr. Britton and myself, and each of 
us at once resolved to describe it as a species. Mr. Oakes, who 
first described it from Robbins’ specimen as a variety, had a strong 
feeling that it was distinct, and wrote on the label, “If this is a 
-new species I should be glad to have it called S. Robbinsii.”’ Out 
of deference to Mr. Oakes, I give him credit for the species. Upon 
the same sheet, Dr. Gray writes, “S. aureus, var. Robbinsii (An Sp. _ : 
Nov. ?),” but in later years, misled by its great resemblance to S. | 
aureus, he assigns it to a very insignificant position. ~
