plant surrounding a pond of about 2 acres nearly 2 miles southeast of 

 Palmyra. It has also been found by Edna Banta in Jefferson County. 



Atlantic coast from s. N. Y. to Fla., westw. through the Gulf States to

5. Ranunculus oblongifolius Ell. Map 961. I found this species to be 

 frequent in a low, open woods in the Hunley Bottoms about a mile north- 

 east of Huntingburg in Dubois County, and in three widely separated 

 places in Posey County where it was common in hard, white clay soil in 

 very wet, fallow fields. Winona Welch collected it in Graebert's woods 

 about 8 miles southwest of Mt. Vernon in Posey County, and Edna Banta 

 found it in the "flats" in Jefferson County.

 there are no reports from the northwestern part. The most northern

 This buttercup is frequent to common throughout the state and is found 

 in all kinds of habitats except in very sandy or very wet places. Where

 pernicious weed. 



Lab. to Man., southw. to Fla., Ark., and Colo.
