Pursh, 2. p. 574. 
I know not whether the plant I am about to describe be the real R. Dis- 
color of Pursh; it has many points of resemblance. 
Plant about two feet high, a little hairy, with a few long, slender naked 
branches. Leaves alternate, sessile, spathulate-lanceolate, triplinerved, 
finely and sparingly denticulate, sprinkled like the stem with very short 
hair, sometimes slightly cordate at base. Flowers few, small, terminal. 
The leaves of the involucrum oval, rather obtuse, a little hairy. Florets of 
the ray twelve to fourteen, lanceolate, two-cleft at the summit, externally 
hairy, scarcely longer than the involucrum; of the disk very numerous, dark 
purple. Seeds four-angled; the pappus a slight margin. Receptacle con- 
vex, chaff oblong, keeled, dark purple and fringed at the summit. The flo- 
rets of the ray in this plant are trilobed and have, at least when dry, their 
bright yellow, the base or under surface dark orange. 
To the preceding species this has great affinity, but it is altogether less 
hairy, its leaves are fewer, smaller, and more finely denticulate, its branches 
summits fewer, more slender, and naked. 
Grows in the western districts of Georgia. 
Flowers August and September.
