Solidago uniligulata (DC.) Porter 



wide which does not agree with the facts. The character described is the 

 sunken area between the veinlets and has nothing to do with the prominent 

 lateral veins. The surfaces of the blades appear as "hammered metal" 

 without a design.

17b. Solidago rugosa var. celtidifolia (Small) Fern. (Rhodora 38: 223- 

 224. 1936.) The range of this variety is given by Fernald to include 

 Indiana. This range is based upon a specimen labeled "Valparaiso, Indiana, 

 Sept. 17, 1927. Benke, 5096" in the Gray Herbarium. I have not seen 

 this specimen.

18. Solidago uniligulata (DC.) Porter. (Solidago uniligulata var. neg- 

 lecta (T. & G.) Fern., Solidago uliginosa Nutt. of Indiana authors, and 

 Solidago stricta Ait. of early Indiana authors.) Map 2023. Infrequent 

 throughout the lake area and in a few springy places south of it. This 

 goldenrod is strictly a bog and marsh plant. It is conspicuously variable in 

 size, in branching of the inflorescence, and in the number of rays to a head. 

 I have had an opportunity to study it in several places where it grew in 

 abundance. One place was a decadent marsh on the south side of Little 

 Long Lake, Noble County. This marsh covered about an acre and in places 

 large colonies of Cornus and Salix were established on the border. In the 

 center of the marsh, which was the wettest part, grew very slender plants 

 of this species, while in the drier part on the border of the shrub zone, grew 

 larger and branched plants. Between these two extreme habitats inter- 

 mediate plants were found. I collected a large series for future study which 

 has convinced me that the difference in the plants was a result of environ- 

 ment. The reason for the difference, I do not know. I have found this 

 species in both marl and peaty habitats. 



Newf. to Minn., southw. to N. C, Ohio, Ind., and 111. 



18a. Solidago uniligulata var. levipes Fern. (Rhodora 17: 7. 1915.) 



I think this is merely a glabrous form of the species and is found with it.
