3381. SANGUISORBA [Rupp.] L. Burnet 



1. Sanguisorba canadensis L. American Burnet. Map 1172. This 

 species has been found in only two places in the state. Blatchley found it 

 in Vigo County, August 1, 1892, along the Vandalia Railroad through the 

 Heckland Prairie north of the Otter Creek Junction, about 6 miles north- 

 east of Terre Haute, and along the same railroad near Heckland, in sec. 8, 

 about 8V2 miles northeast of Terre Haute. I found a few specimens in the 

 last named place in 1917. In 1923 I found a few specimens in a springy 

 place along Flint Creek about 3 miles northwest of Westpoint in Tippe- 

 canoe County. 



Lab. to Man., southw. to Va. and Ind., and in the mts. to Ga.

Eileen Whitehead Erlanson, who has for years intensively studied the 

 wild roses of North America, has had them under cultivation in the 

 Botanical Garden of the University of Michigan, and has written volum- 

 inously about them, has examined all of my specimens and written the 

 following key. It is now known that some of the species freely hybridize 

 and when specimens of hybrids are at hand it is difficult to name them. 

 Our native species nos. 4, 5, and 6 are extremely variable and the more 

 conspicuous forms have been named. Some of these forms are described in
