separated until 1901. Campanula aparinoides is more southern in its dis- 

 tribution. Since most of our reports were made before the preceding 

 species was described it is impossible to say to which one, the reports 

 should be referred. I believe all, or almost all, reports from the lake area 

 should be referred to Campanula uliginosa. Campanula aparinoides is rare 

 in northern Indiana.

5. Campanula rotundifolia L. (Malte. Critical notes on plants of 

 Arctic America. Rhodora 36: 188-190. 1934.) Harebell. Map 1968. In 

 sandy or gravelly soil usually on the slopes and ledges of banks of streams 

 and lakes. This is the true species and has the stems densely pubescent at 

 the base and is found in Europe and western America and rarely inland or 

 in eastern America. I found it on the gravelly bank of the south side of 

 Lake Gage in Steuben County, and on the slope of the high, wooded bank 

 of the south side of North Twin Lake in Lagrange County where it was 

 growing side by side with the glabrous form which was common, while the 

 species was rare.

5a. Campanula rotundifolia var. intercedens (Witasek) Farw. Map 

 1969. This is the glabrous form of the species; it is found in the interior 

 and eastern North America. The habitat is the same as that of the species. 

 I found it common, however, on the north side of the Wabash River below 

 Georgetown in Cass County, in the upper crevices of the 10 foot rock cliff 

 which forms the bank of the river. 



This variety is more or less frequent throughout most of the lake area 

 where its habitat is well represented. 



The var. arctica Lange has been reported by Peattie as occurring in the 

 dunes. This is merely a dwarf form of the preceding variety and I regard 

 it as an ecological variation without taxonomic significance.
