13. Ranunculus fascicularis Muhl. Tufted Buttercup. Map 969. I 

 have found this species in dry, sandy soil locally in only the northern 

 counties, but it has been reported from Clark, Dearborn, Decatur, Frank- 

 lin, Jefferson, Monroe, Shelby, and Vigo Counties and from the Lower 

 Wabash Valley. 



Eastern Mass., Ont., Wis., and Minn., southw. to N. C, Tex., and Kans. 



14. Ranunculus pennsylvanicus L. f. Pennsylvania Buttercup. Map 

 970. Infrequent in wet places about lakes and in marshes and rarely in 

 ditches in the lake area. Coulter reported it in his Catalogue for Mc- 

 Dougal from Putnam County, but there is no specimen in the herbarium 

 of DePauw University where MacDougal's Indiana specimens are de- 

 posited.

15. Ranunculus repens L. var. villosus Lamotte. (Fernald. Varia- 

 tions of Ranunculus repens. Rhodora 21: 169. 1919.) Map 971. This 

 species was reported by the majority of the earlier authors and un- 

 doubtedly all or nearly all of the reports should be transferred to other 

 species. Coulter, in his catalogue, transferred most of them to Ranwi- 

 culus septentrionalis. It has recently been found as a weed in a lawn 

 at Goodland, Newton County, by Madge McKee, and as a weed in a lawn 

 in Bedford, Lawrence County, by Ralph M. Kriebel. It doubtless is more 

 widely distributed in our state than our reports indicate.

16. Ranunculus hispidus Michx. Bristly Buttercup. Map 972. This 

 species, as I am treating it, seems to me to be a complex but I am not 

 able to divide it. It has been reported from seven counties. I have 67 

 sheets from Indiana and these come from all parts of the state and from 

 many habitats— from bogs to the crests of our highest and driest hills, 

 and from the shade in woods to the brilliant sun of roadsides and prairies. 

 The foliage varies so widely that no classification can be made on this
