ists in regard to the true conception of the species but little 

 can be done with our material.

(c) Ascending or creeping by stolons. 



Ranunculus repens L. Sp. PI. p. 554. 1753. 



Habit and foliage closely resembling Ranunculus septen- 

 trionalis Poir., more or less hairy, spreading by runners 

 and forming patches ; leaves often blotched ; achenes mar- 

 gined, the beak stout, short, and slightly bent. 



The only genuine specimens of this species we have 

 seen are from Muscatine and Johnson counties. Messrs. 

 Nagel and Haupt reported the species from Scott county 

 which report is confirmed by Messrs. Barnes, Reppert and 

 Miller. Prof. Bessey reports the species from Poweshiek, 

 Warren and Story counties. Prof. Hitchcock does not 

 include this species in his Catalogue of the plants of 

 Ames, Story county. It seems entirely probable that the 

 species considered by Prof. Bessey was Ranunculus septen- 

 trionalis Poir. which species is R. repens of Gray's Man- 

 ual, 5th edition, the current edition at the time of the 

 publication of Prof. Bessey 's article. The same in part 

 may be said in regard to Messrs. Nagel and Haupt's report 

 of the species from Scott county. The species blooms in 

 low grounds from May until July, and is apparently infre- 

 quent.
