Solidago grammifolla IL.) Salisb. 

 var. Nuttallii (Greene) Fern. 



in northern Indiana and very local in southern Indiana in similar habitats. 

 Now found mostly along roads and railroads. 

 Mass. to Sask., southw. to Ga. and Tex. 



23. Solidago ohioensis Riddell. Map 2027. Infrequent in marly marshes 

 in the lake area and very local in springy places south of it. It is usually 

 common where it occurs. I once saw a colony of about five acres on the 

 wide marl border of the south side of Lake Pleasant which is located just 

 south of the Michigan State line in Steuben County. Only the most tolerant 

 calciphiles were associated with it such as Triglochin maritima, Eleocharis 

 pauciflora var. Fernaldii, Juncus brachycepludus, and Lobelia Kalmii. This 

 species is always indicative of a limy soil and if the soil is not too alkaline 

 Lobelia Kalmii and Parnassia glauca will be found with it. 



N. Y., Ont. to Wis., southw. to Ohio and 111. 



24. Solidago Riddellii Frank. Riddell Goldenrod. Map 2028. Infre- 

 quent in the lake area and local south of it where its habitat occurs. It is 

 found in springy and marshy places that are somewhat alkaline. It is often 

 found closely associated with Solidago ohioensis, which flowers about 10 

 days earlier, but in a wetter habitat. This zonal distribution is often quite 

 conspicuous. It is to be noted that where this species grows in numbers the 

 plants vary greatly in size, doubtless due to some habitat factor.

25. Solidago graminifolia (L.) Salisb. var. Nuttallii (Greene) Fern. 

 (Solidago graminifolia of early Indiana authors, Solidago hirtella (Greene) 

 Bush, and Euthamia hirtella Greene.) Map 2029. Infrequent to frequent in 

 every county of the state. It prefers a moist rich soil but adapts itself to 

 almost all kinds of soils and habitats. It is usually found in large colonies 

 where its spread is not limited. Frequent along roadsides and railroads, in 

 open places in alluvial soil along streams, in open woodland, and in fallow 

 fields.
