bracts yellowish with a greenish midrib, lanceolate and acute ; 
achenes hirsute-strigose ; ligules 3 mm. long and nearly I mm. 
wide. 
This is closely related to Solidago nana, but differs in the 
narrower, lanceolate, and acute bracts. Its pubescence is usually 
also denser and whiter. Platt’s specimens were labeled S. ms- 
souriensis v. montana Gray, to which it has no relationship, only 
resembling it a little in habit and in the narrow bracts.

This species is related to Solidago mollis, S. radulina, and S. 
Radula, It differs from the first in the thinner, green, more decid- 
edly obovate, and sparingly pubescent leaves, and the open, few- 
branched panicle; from S. radulina in the larger, thinner leaves, 
the open and more leafy inflorescence, and the acute instead of 
obtuse bracts; and from S. Radu/a in the thin, broad leaves, large, 
ample upper stem-leaves, the small inflorescence, and acute bracts.
