9 S. caesia Ait. St. erect, round, smooth and glaucous, often flexuous ; Ivs. 

 smooth, linear-lanceolate, lower ones serrate ; roc. axillary, erect, ach. minutely 

 pubescent. A very elegant species, in thickets and dry woods, Can. and U. S. 

 Stem 2 to 4f high, of a bluish-purple color, terete and slender, somewhat flexu- 

 ous, simple or branched. Leaves 2 5' long, ending in a long point, sessile, 

 glaucous beneath. Racemes axillary, numerous, short. Flowers of a deep, rich 

 yellow. Rays 3 6, once and a half the length of the involucre. Aug. (S 

 axillaris, Ph.) 



p. FLEXICAULIS. St. flexuoua, angular ; Ivs. ovate-lanceolate, longer than the 

 subcapitate racemes. Leaves about 2' by V. Rays pale yellow. (S. flexi-

 spicuous rays. A coarse showy golden rod, iu woods, White Mts., N. H., Wil- 

 loughby and Green Mts., Vt. It is remarkable for the long slender stalks of the 

 lower ovate leaves, and for tho large hds. which exceed in size most other spe-

 ray elongated; has. large, about 3Q-flowered ; scales very thin, acute. This is the 

 only species common to the two continents. One of its numerous varieties is 

 seen scattered here and there on the lower summits of the White Mts., N. H., 

 Essex Mts., N. Y.. L. Superior, C. W., also? Mts. of N. Car. The hds. are few, 

 sometimes one only, but larger than those of most other species, and" of a rich, 

 golden yellow. St. often purple, 2 to 3' high, simple, with axillary and ter- 

 minal flowers. Aug. (S. glomerata MX. whose description answers well to tho 

 larger specimens of S. virgaurea.)

 Newfoundland. St. G to 12' high, somewhat glutinous. Rac. slender, strict.

13. Taller ; hds. more numerous, in short, glomerate clusters, forming a dense, 

 slender, interrupted rac. Near the Willey House, White Mts.

 (>' to If long, composed of small clusters. Sept., Oct.

 very entire, rough-edged, radical Ivs. serrate, very long; rac. paniculate, erect; 

 ped. smooth; hds. about 10-flowered. In wet woods, N. States. St. (and every 

 other part) very smooth, about 2f high. Lvs. 2 to 4 to 8' by i to i to 1', tower

 of short, dense, appressed racemes. Aug. 



15 S. speciosa Nutt. St. smooth, simple ; Ivs. lanceolate, entire, and scabrous, 

 on the margin, thick, tho radical and lower Ivs., subserrate, very broad; rac. erect, 

 numerous, forming a terminal, thyrsid panicle; pedicels shorter than the invol., 

 pubescent; rays largs, G to 8. Woods, Mass, to Ohio and Ga. A noble species,
