9 S. coesia 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. arid U. S. 

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

 oas, 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 5 7, once and a half the length of the involucre. Aug. (S. 

 axillaris, Ph.) 



/?. FLEXICAULIS. St. flexuous, angular; Ivs. ovate-lanceolate, longer than tho 

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

 caulis, Ph. not of L.)

 spicuous rays. A coarse showy golden rod, in woods, White Mts., N. II., Wil- 

 loughby and G-reen Mts., Vt. It is remarkable for the long slender stalks of tho 

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

 cies. St. 1 to 3f high, racemes axillary and terminal, usually in a thyrse-liko 

 panicle. Aug. (S. virgaurea, Bw.)

 only species common to tho two continents. Ono of its numerous varieties is 

 seen scattered here and there on tho lower summits of tho White Mts., N. II., 

 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. whoso description answers well to tho 

 larger specimens of S. virgaurea.)

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

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



13 S. virgata MX. Glabrous, strict, virgate, tall, simply racemom at top; Ivs.

 Damp pine barrens, N. J. to Fla. St. 3 to 5f high. Lower Ivs. 3 to 4' long,

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



14 S. stricta Ait. Smooth ; st. strict, erect, simple ; cauline Ivs. lanceolate, 

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

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

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