Soli dago Chrysopsis. 



5 mm. high, 



Perennial, slender, glabrous. Stem erect or ascending, wire- 

 like, 2-3 dm. tall, paniculate above, nearly naked : leaves mainly 

 basal or near the base of the stem, 6-20 cm. long or those on stem 

 shorter ; blades elongated linear, acute, entire or nearly so, acute, 

 curved, slender-petioled : heads in narrow pan 

 conspicuous on account of the silvery-white pappus : involucres 

 becoming lax : bracts thin, linear-lanceolate or linear, rather ob- 

 tuse : flowers 1 1 — 14 : rays yellow, several, linear: achenes finely 

 pubescent.

in habit to that 



of Solidago laxa. The stems bear very few leaves. The thin nar- 

 row linear or linear-lanceolate bracts of the involucres form a 

 strong contrast with the thick broad bracts of Solidago gracil- 

 lima. The several rays are also diagnostic so far as Solidago gra-

Solidago flaccidi folia. 



Perennial, glabrous below the inflorescence, bright green. 

 Stems erector ascending, 7- 11 dm. tall, simple or nearly so, 

 ridged, slightly zigzag : leaves alternate; blades elliptic, 6-15 cm. 

 long, thin, acuminate, sharply serrate above the cuneate base, ses- 

 sile or nearly so : heads few in axillary clusters, short-pedunclcd, 

 4 mm. high, clusters subtended by spatulate or elliptic-spatulate 

 bracts: involucres campanulate : bracts linear, finely pubescent, 

 obtuse, green or green-tipped: flowers 5-7, crowded : rays yel- 

 low, oblong or ovate-oblong, 3 mm. long : achenes pubescent. 



On hillsides, Rome, Georgia. Fall. Like so many others of the 

 species of the Southern States, Solidago flaccidifolia will doubtless 

 prove to be a local species. It is most closely related to Solidago 

 pabcns from which it differs in the almost glabrous foliage, only 

 the upper part of the inflorescence is pubescent and hairs are sparse, 

 short and not spreading. The leaf-blades are larger and their 

 margins are not toothed so far below the middle. The involucres
