The type specimen is rather more hairy than the culti- 
vated plant; its leaves are much smaller, and all are 
subsessile, but only the upper ones are present. There 
are variations, too, in the depth of the lobing of the leaves, 
and in the breadth of the ultimate lobes. 
Descr.—A perennial, subshrubby, branched herb, erect, 
two to four feet high, densely leafy, everywhere shortly and 
softly pubescent; branches very spreading, subterete or 
obscurely angular, the stronger about half an inch in 
diameter. Leaves spreading, subsessile, or long-petioled, 
dark green, somewhat viscid, bipinnatifid, deltoid, one to 
six inches long, three-quarters to six inches broad at the 
base; ultimate lobes ovate, rounded at the apex, very 
minutely apiculate, the terminal ones narrower and acute ; 
petioles up to an inch and three-quarters long, like the 
rhachis narrowly winged and channelled on the upper side. 
Flower-heads shortly peduncled, an inch and a half to two 
inches in diameter, with bright yellow florets. Outer 
bracts of the involucre herbaceous, green, pilose, spathulate- 
oblong, nearly a quarter of an inch long, acute; inner 
larger, membranous, oblong, yellow, pilose outside. Ligu- 
late florets usually eight, oblong, two-thirds to slightly 
more than three-quarters of an inch long, a quarter to a 
third of an inch broad, minutely toothed at the apex. 
Receptacle flat, with narrowly oblong scales slightly longer 
than the achenes. Achenes oblong-linear, about a fifth of 
an inch long, compressed, setulose on the margins and on 
the inner side. Pappus small, of short, setose hairs, and 
two opposite bristles five or six times shorter than the 
achene.—§, A, Sxan.
