Solidago humilis, Pursh, of the Eastern States, and its Allies. 
(Prates CLIII-CLV.) 
Solidago Virgaurea, I.. has long been regarded as native in 
the higher latitudes of North America, and appears as such in the 
Flora of Torrey and Gray. In the 5th edition of his Manual, 
which covers less territory, Dr. Gray admits the species, but re- 
stricts it to two varieties, alpina, Bigelow, and humilis (Pursh).
