high, somewhat secund on the spreading, often 
very slender and elongated branches of the pani- 
cle; bracts of the involucre oblong, very obtuse; 
rays 6-10; achenes puberulent, or glabrous below. 
In dry soil, Tennessee and Missouri. July-Aug.

Solidago pulchérrima A. Nelson (S. lJongipetiolata

ward into Wisconsin and Missouri, differs mainly by 
somewhat larger heads, and is here regarded as one of 
the many races of S. nemordalis Ait.
