332 LXXV. COMPOSITE. Solidago. 



Stem 2— Sfhigh, yellowish-green. Leaves U— 3' by 3—5", with a strong, yel- 

 lowish midvein, but no veinlets. Panicle inclined. Racemes 2—3' long, 

 spreading, each generally with a leaf at base, and a simple row of small heads 

 on the upper side. Jl.— Sept.— The only species of solidago which has proper- 

 ties generally considered either agreeable or useful. The leaves are aromatic 

 and yield by distillation a fragrant volatile oil from the pellucid rescrvoii's. 

 They are a good substitute for tea, and have been exported to China.

St. erect, hairy; lvs. lanceolate, lower ones deeply serrate, rough and

 or serrate, numerous both upon the stem and branches. Branches widely 

 spreading, each terminating in a recurved panicle with the flowers turning up- 

 wards. Scarcely two of the plants look alike. The branches are very widely
