Wooded hill-sides of Kentucky, Rafincsque ! Dr. Short ! S^v. to the 

 mountains of North Carolina, as far east as Wilkes County, Mr. Curtis ! 

 and of Georgia, Mr. BucMey ! Aug.-Oct. — Stem 2-4 feet high, pubescent, 

 as well as the lower surface of the leaves, usually with a few lax and spread- 

 ing or recurved branches at the summit. Radical leaves deeply cordate, 

 3-5 inches broad, more or less acuminate, finely veined and reticulated, 

 somewhat triplinerved ; the cauline gradually reduced in size and less cor- 

 date ; the upper merely obtuse at the base; the uppermost nearly sessile 

 and entire. Heads about 3 lines long. Rays a little longer than the disk. 

 Achenia almost glabrous. — This plant is more closely allied to Solidago than 

 to Gutierrezia (Brachyris) ; only differing from the former, indeed, in its cor- 

 date leaves and very short pappus. The latter does not consist of 5-6 paleas, 

 as stated by De Candolle ; but of about 20 linear squamelte, not longer than 

 the ovary, which, if prolonged to the length of the corolla, would form 

 bristles scarcely stronger than those of Solidago.

Solidago, Euthamia, & Clirysoma, Nutt. 



Heads few-many-flowered ; the ray-flowers few (1-16), or sometimes 

 wanting; those of the disk tubular, perfect. Scales of the oblong involucre 

 imbricated, appressed, destitute (except in Chrysastrum) of foliaceous or 

 herbaceous tips. Receptacle narrow, mostly alveolate. Appendages of the 

 style lanceolate. Achenia many-ribbed, somewhat terete. Pappus simple, 

 of numerous scabrous capillary (mostly equal) bristles. — Perennial herbs, 

 rarely suffruticose (the greater portion North American), mostly with strict 

 or virgate stems, and sessile alternate cauline leaves ; the radical never cor- 

 date. Heads in terminal or axillary racemes or clusters, sometimes corym- 

 bose ; the pedicels often unilateral. Flowers yellow (the rays white in S. 

 bicolor), never turning purplish. 



§ 1. Herbaceous: scales of the {much imbricated) involucre with squarrose 

 herbaceous tips : rays 12-16, or entirely wanting: the inner bristles of the 

 unequal pappus slightly thickened at the apex! : heads in glomerate clus- 

 ters or racemes disposed in a compound spike or panicle : leaves ample, 

 veiny ; the loioer narrowed into petioles. — Chrysastrum. 



♦ Rays Tume: corolla of the disk deeply ^-defl : inner bristles of the pappus manifestly 

 davellate-thickened at the apex. 



1. S. discoidea: stem somewhat villous, branching above ; leaves mostly 

 pubescent ; the lower ovate, coarsely toothed or serrate, abruptly narrowed 

 into a margined petiole ; the upper oblong or ovate-lanceolate, acute at each 

 end, somewhat petioled ; the uppermost entire ; racemes paniculate, often 

 glomerate ; scales of the canescently pubescent involucre linear-lanceolate, 

 acute, squarrose; disk-flowers 10-15. — Aster? discoideus, Ell.! sk. 2.
