Ranunculus fascicularis Muhl. 



local south of this area. Our plants vary from glabrous to pubescent all 

 over. 



Throughout N. A. except in the extreme north; also in Eurasia. 



9. Ranunculus micranthus Nutt. (Ranunculus cymbalist es* Greene.) 

 Map 965. There are seven reports for this species, all from the southern 

 half of the state. My specimens are from near the bases of slopes wooded 

 with sugar maple and from the crests of wooded ridges. It is either very 

 local or so inconspicuous that it is overlooked.

10. Ranunculus bulbosus L. Bulb Buttercup. Map 966. There 

 are reports from seven counties. Nieuwland collected it in Lake and 

 Porter Counties and the specimens are in the herbarium of the Univer- 

 sity of Notre Dame. Clark collected it in Marshall County and the speci- 

 men is in the National Herbarium at Washington, D. C. A specimen col- 

 lected by Flora Haas in Owen County is in the herbarium of Indiana 

 University.

11. Ranunculus recurvatus Poir. Hooked Buttercup. Map 967. In- 

 frequent to frequent or even common in moist, rich woods throughout 

 the state. 



N. S. to Man., southw. to Fla., Ala., Mo., and Kans. 



12. Ranunculus acris L. Tall Buttercup. Map 968. This species 

 has been reported from eight counties, mostly northern. It is local along 

 railroads and roadsides. I have seen it abundant in a few places, and in 

 time no doubt it will become a weed in favorable habitats. My Allen 

 County specimen, no. 47063, is exceptional in that the blades of the stem 

 leaves are divided into three parts and these are on petiolules 0.5-3 cm long.

* Fernald makes this name a variety and calls it Ranunculus micranthus var. cym- 

 balistes (Greene) Fern. (Rhodora 41: 543. 1939.)
