1 S. pauciflosculosa MX. Shrub, much branched, glabrous, glaucous and 

 somewhat viscid; Ivs. somewhat lanceolate and linear, obscurely 3-veined, obtuse, 

 sessile, entire ; panicle compound, of erect racemes ; fads. 5 to 7 -flowered, with 1

 serrate, the upper ovate-lanceolate ; rac. erect, in a virgate or thyrsoid pan. ; hds. 

 discoid, about I2-flowered; scales downy-canescent, the acute herbaceous tips 

 squarrous-spreading. Ga. and Fla. (uplands), to La. Plant 3 to 4f high, remark- 

 able for its rayless fls. and squarrous aster-like involucre. Lower Ivs. 3 to 4' long, 

 gradually reduced upwards. Sept., Oct. 



3 S. brachyphylla Chapm. Rough-pubescent; Ivs. numerous, appressed-ser- 

 rate, spatulate, oval and ovate, glabrous : rac. secund, in virgate panicles ; scales 

 erect (not spreading), obtuse, smooth; hds. discoid; disk-flowers 5 to 6. Mid. Fla,, 

 uplands (Chapman). Tall (4 to 6f), with erect leafy branches. St. Ivs. 1' long,

 spreading green tips ; hds. many flowered; rays 10 12, elongated. A handsome 

 species, found on rocky hills, Can. to Penn. Stem 2 5f high. Heads very

5 S. squarrulosa (T. & G.) Pubescent, striate; Ivs. rough, numerous, oval or 

 lanceolate, the upper entire, the lower serrate, all abruptly contracted at base but 

 scarcely petiolate; hds. large (20 to 25-flowered), in a terminal, virgate raceme; 

 rays 6 to 10 ; scales linear or lance-subulate, with loose herbaceous tips, the outer 

 spreading, bract-like. Uplands, N. Car. to Fla. and La. St. 2 to 31 high, often 

 branched above. Lvs. 1 to 2 'long. Aug., Sept (S. squarrosa Nutt S. petio-

 serrate, short-stalked; rac. short, dense, axillary, paniculate- virgate above; in vol. 

 scales obtuse; rays about 8, whitish. Woods and dry hills, Can., N. Mid., & "W. 

 States. Eemarkably distinguished among the solidagos by having white or 

 cream-colored rays. St 2f high, a little hairy. Lvs. hairy on both sides, mostly 

 entire, gradually reduced in size upwards. Axillary clusters approximating above 

 into a terminal, interrupted spike. Kays short and obscure, JL, Aug. (Aster 

 bicola Nees.)

 each end, subsessile ; clusters axillary, loose, much shorter than the Ivs. ; ped. 

 villous : scales glabrous, acutish, rays 4 to 6, dik-flowers 9 to 12 ; ach. compressed, 

 glabrous. Interior of Ala. (Buckley). St 2 to 3f high? Lvs. as large as in 

 No. 8, the hds. larger. Oct. 



8 S. latifolia MuhL St somewhat flexuous, angular, smooth below, pubescent 

 above; Ivs. broadly ovate, acuminate at each end, deeply serrate, pubescent be- 

 neath ; petioles marginal ; rac. axillary and terminal ; ach, silky pubescent. A 

 singular and well-marked species common in dry woods and by rocky streams, 

 U. S. and Can. St slender, simple, about 2f high. Lvs. 3 to 5' by 2 to 4', with 

 acute, often long-acuminate serratures. Clusters very short, axillary, the stem 

 ending with a long terminal one. Hds. few. Sept. Variable. The clusters are
