fallow fields. The plant is highly variable even as to the number of achenes. 

 Since I am not recognizing this variety, its distribution in the state is not 

 given, although I have specimens from the northern to the southern border. 

 Mass., Ont. to Kans., southw. to Fla. and Tex. 



4. Hieracium longipilum Torr. Long-beard Hawkweed. Map 2240. 

 This species has been reported from the dune area, Lower Wabash Valley, 

 and from Parke, St. Joseph, Steuben, and Vigo Counties. I have seen the 

 Parke County specimen and it should be referred to Hieracium Gronovii. 

 This hawkweed is a weed in sandy fallow fields in the vicinity of Heaton 

 Lake, Elkhart County, and in several fields in northeastern St. Joseph 

 County. It is probably more widely distributed. I noted it as frequent in 

 the old Beaver Lake Basin about 3 miles south of Lake Village, Newton 

 County. 



Ont. to Minn., southw. to Ind. and Tex. 



5. Hieracium venosum L. Rattlesnake-weed. Map 2241. I have 

 found this species in three places in Clark County and in no other place. A 

 few plants were found on the crests of ridges with chestnut oak and Vir- 

 ginia pine. It has also been reported from Floyd, Jefferson, Monroe, and 

 White Counties. I have not been able to check any of these reports. I have 

 searched the herbaria of the Field Museum and of the University of 

 Illinois for the Lake County specimen, but I did not find it. N. C. Fas- 

 sett says there is no specimen in the Umbach herbarium at the University 

 of Wisconsin. Specimens of Hieracium Gronovii might be mistaken for 

 this species.

6. Hieracium paniculatum L. Map 2242. Infrequent to very local in 

 the counties shown on the map. It has been reported from Jefferson, 

 Johnson, Lake, and Monroe Counties. N. C. Fassett says that the Umbach 

 specimen from Lake County is H. canadense. It prefers slightly acid and
