been collected, however, and the only specimen is in the herbarium of the 

 University of Notre Dame, having been collected at Notre Dame. 

 Tropical regions, almost cosmopolitan. 



4. Oxalis stricta L. (Xanthoxalis stricta (L.) Small.) Upright Yel- 

 low Wood Sorrel. Map 1295. Mostly in fallow or abandoned fields, along 

 roadsides and railroads, and less frequent in woodland ; apparently pre- 

 ferring an impoverished soil. Throughout the state but more abundant in 

 the southern part. 



P. E. I. to B. C, southw. to Fla., Tex., and Mex. 



4a. Oxalis stricta f. viridiflora (Hus) Fern. (Rhodora 38: 425. 1936.) 

 This is a form with green petals. It is represented in my herbarium by 

 a specimen from Gibson County collected by Schneck. 



4b. Oxalis stricta var. piletocarpa Wieg. (Rhodora 27: 123. 1925.) I 

 have this variety from only Bartholomew and Fountain Counties. There 

 is a specimen from Putnam County collected by Grimes, which is in the 

 herbarium of DePauw University. 



P. E. I., southw. to N. J.; also in Wyo. 



5. Oxalis florida Salisb. (Rhodora 27: 133. 1925.) (Oxalis filipes Small, 

 Xanthoxalis filipes Small, and Oxalis Brittoniae Small.) Map 1296. Our 

 only specimens are from a wooded bluff along the Ohio River about 6 miles 

 above Cannelton and from a wooded bluff in Jefferson County. 



I reported Oxalis Brittoniae Small from Steuben and Wells Counties. 

 (Proc. Indiana Acad. Sci. 1904: 220. 1905.) I am now referring these 

 specimens to Oxalis europaea Jordan. 



Pepoon reported Oxalis filipes Small from Lake and Porter Counties for 

 Umbach but Fassett (Rhodora 35: 200. 1933) refers the Lake County 

 specimen to Oxalis stricta and says there is no specimen labeled Oxalis 

 filipes from Porter County. 



Maine to Fla., "mainly toward the coast but apparently not on the 

 Coastal Plain" (Wiegand) ; inland in Ind.
