1. Polanisia graveolens Raf. Clammyweed. Map 1056. This species 

 grows in very sandy soil and is usually found on sand and gravel bars of 

 streams, along roadsides and railroads, and rarely in fallow or cultivated 

 land along streams. On large sandbars it often forms extensive colonies.

2. Polanisia trachysperma T. & G. Map 1057. This species was found 

 by Madge McKee in sandy soil along the roadside, 2 miles west and ll/ 2 

 miles south of Lake Village, Newton County. It is a western species and 

 there is a slight possibility of its having been introduced. The locality 

 where it was found is within the prairie area. The nearest railroad and 

 the nearest main highway are both two miles to the east. I think this 

 is an eastern extension of the range of the species. Found at the same 

 place on Sept. 4, 1938, by Indiana botanists on a field trip and specimens 

 were collected. 



This species was included in a list of plants reported from Monroe 

 County by Andrews. No data accompanied the report and no specimen 

 was preserved. Since the habitat does not occur in Monroe County, it must 

 have been a waif if the plant was determined correctly.
