9 S. cassia 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 flcxu- 

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

 axillaris, Ph.) 



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

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

 caulis, Ph. not of L.)

 Ivs. smooth, ovate, coarsely and sharply serrate, acute, the lower on long petioles, the 

 upper subsessile, lanceolate; rac. mostly simple, short; has. large, with con- 

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

 loughby and Green Mts., Yt. 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-like 

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

 ray elongated; hds. large, about ^-flowered; scales very thin, acute. This is tho 

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

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

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

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

 golden 3 r ellow. 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.)

 petiolate, obtuse and crenate-serrato at apex; the cauline oblanceolate. and lan- 

 ceolate, acute; rac. simple or paniculate; hds. middle size, about \2-flowcred; 

 scales oblong, oUuse; rays short. Rocks along mountain streams, Yt., N". II., to 

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

 Lvs. of the stem about 2' by 3 to 4", serrulate, lids. G to 8 rayed. Aug., Sept. 



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

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



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

 entire, thickish, oblong-lanceolate, and oblanceolate, rough edged, the lowest 

 subserrate, petiolate; hds. about 15-flowzred ; rays 5 to 7 ; ach. pubescent. 

 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 i to l' lower

 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, thyrsoid panicle ; pedicels shorter than the invol, 

 pubescent; rays Iarg3, 6 to 8. Woods, Mass, to Ohio and Ga. A noble species,
