‘ Solidago glaucophylla sp. nov. 
Perennial, with a branching rootstock ; stems slender, pale, gla- 
brous up to the sparingly pubescent inflorescence; leaves glabrous, 
glaucous, minutely ciliolate on the margins, rather thick, linear- 
oblanceolate or the upper linear, triple-nerved, 6-10 cm. long, 
4-10 mm. wide, entire, acute ; inflorescence a round-topped panicle, 
the branches somewhat recurved-spreading and somewhat secund ; 
heads about 5 mm. high; bracts oblong, obtuse, or the outer 
lance-oblong, acutish ; rays short, 2-2.5 mm. long, 0.7-0.8 mm. 
wide ; achenes slightly strigose-hirsute. 
This species is related to Solidago missourtensis and S. glaber- 
vima, but differs from both in the narrow, entire, glaucous leaves 
and the thicker, oblong and obtuse instead of linear-lanceolate and 
acute bracts. The type grew on dry plains at an altitude of 
1000 m.
