 E. spathulata, Micnx. Snigulcse : stem slender, 8 inches to 3 feet high : leaves obovate 

 or spatnlate, or the uppermost lanceolate, denticulate or sparingly serrate, their pubescence 

 wholly appres.sed and short; radical and lowest cauline leaves mostlr roundish at summit at 

 base abruptly contracted into a winged petiole, or even subcordate: peduncle usually elon-

-R. speciosa, Wexderoth. Sparsely strignlose or hispid, or glabrate : stem 1 to 3 feet 

 high, u,sually with spreading branches terminating in long naked peduncles: leaves ovate- 

 lanceolate or the upper elongated-lanceolate, bright green, irregularly serrate or some 

 laciniately dentate, acute or acuminate; radical and lower cauline oblong or ovate, 3-5- 

 nerved, abruptly contracted into long margined petioles: ravs 12 to 20, elongated, at lenc?th 

 inch and a half long: disk two-third,s to three-fourths inch high at maturity, the tips of the 

 purple chaffy bracts sparingly or obscurely ciliate : akenes larger and longer than in the

b. Chaffy bracts of the receptacle with the obtuse tips canescently puberulent or pubescent, and the 

 flowers duller purple; the di-k therefore browner. 



1. Cauline leaves all closel_v sessile or partly clasping, not nervose: bristly style-tips little thick- 

 ened: akenes small : p:ippus very short or obsolete. 



- R. mollis, Ell. Cinereous, the leaves with fine and close pubescence, the (2 or 3 feet high 

 and usually branching) stem with hirsute or villous hairs, leafy: leaves spatulate-oblong, 

 obtuse, obscurely serrate, somewhat triplinerved (1 to 3 inches long): rays 12 to 20, at 

 length inch and a half long and disk fully half-inch high. — 8k. ii. 453 ; Torr. & Gray, 1. c. 

 R. spathulata, Pursh, Fl, ii. 574. — Dry soil, Georgia and Florida. 



2. Cauline leaves mostlv petinled: heads small: quadrangular al^enes only a line long: pappus an 

 obscure crown or hardly any. 



E. Heliopsidis, Torr. & Gray. Almost glabrous, 2 feet high, rather slender, branched 

 above : leaves oblong-ovate, somewhat serrate, triplinerved and with a pair of nearly basal 

 nerves, abruptly contracted, the upper into short and wing-margined, the lower into long and 

 naked petioles : peduncles rather short and corymbose : involucre much shorter than the at 

 length globular disk (which is hardly half-inch high) : rays light yellow, 10 or 12, an inch or 

 le.ss long. — Fl. ii. 310. — Pine woods, Columbus, Georgia, Boykin. Cherokee Co. and Lee 

 Co., jVlabama, Bucklej, J. Donndl Smith. 



3. Cauline leaves mostly petioled and like the radical 3-5-nerved; the veinlets reticulated: heads 

 large and showy: the soon drooping light yellow rays 1 or 2 inches long, and the hemispherical 

 at length somewhat conical receptacle becoming three fourths of an inch high : invoUicre rather 

 small: akenes somewhat compressed: pappus a conspicuous cup-shaped irregularly dentate or 

 crenate crown : stem 2 or 3 feet high, usually simple, and head long-peduncled. 



E. alismsefolia, Torr. & Gray. Glabrous or minutely scabrous : leaves oval, obtnse or 

 sometimes acute, obscurely repand-dentate or entire, 3 to 6 inches long, abruptly contracted 

 into the petiole: rays 10 to 15. — Fl. ii. 310. — Plains and open pine woods, S.Arkansas, 

 W. Louisiana, and adjacent Texas, Lfarenworth, Hale, Drummond. 



E. grandiflora, C. C. Gmeli:--. Hispidulou,^ and- scabrous throughout : leaves more rigid, 

 ovate to oval-lanceolate or uppermost lanceolate, commonly acute or acuminate at both ends, 

 sparingly serrate or denticulate, 4 to 9 inches long : rays 20 or more. — Hort. Bad. Carlsr, 

 1811 ; DC, 1, c. 556 (with some erroneous characters as to chaff and pappus, taken from a
