11. Solidago glaberrima Martens. Map 2013. Local and restricted to 

 the prairie area of the state. It is generally found in colonies because it 

 suckers freely from the roots as does Solidago juncea. 



This is a perplexing species to name because it closely resembles four 

 other species. The original description calls for smooth plants with 

 3-nerved, serrulate leaves that are shining-punctate below. This species is 

 much like small specimens of Solidago juncea but differs in being glab- 

 rous throughout, in having leaf margins sharply serrate; and in having 

 the upper leaves more crowded and elongate. It differs from Solidago 

 missouriensis Nutt. in having the branches of the inflorescence spreading 

 or recurving instead of being erect. Solidago moritura Steele differs in 

 that the leaves are not triple-nerved, at least the lateral nerves, if present, 

 are short and faint.

11a. Solidago juncea Ait. Early Goldenrod. Map 2013a. This is our 

 early goldenrod and is more or less frequent throughout the state. It is 

 generally found in small colonies in dry soils along roadsides, railroads, and 

 fences and on dry gravelly or clayey knolls in open woodland.

12. Solidago gigantea Ait. (Rhodora 41 : 457. 1939.) (Solidago serotina 

 var. gigantea (Ait.) Gray.) Map 2014. Frequent to infrequent in the lake 

 area and infrequent to local south of it. The habitat is the same as that 

 of the variety although it is usually found in wetter places.

12a. Solidago gigantea var. leiophylla Fern. (Rhodora 41: 457. 1939.) 

 {Solidago serotina Ait.) Map 2015. Frequent in the glaciated area but less 

 frequent south of it. It prefers a moist rich soil and is usually found in low
