3. Echinodorus cordifolius (L. ) Griesb. Upright Bur-head. 



"Reported only from the southern part of the State and probably not 

 extending far northward, as the species is southern in its mass distribu- 

 tion." (State Catalogue, p. 624.) The only citation given is Vigo County. 

 This species occurs in abundance in a wet river bottom in Tippecanoe 

 County, where it was collected in midsummer. 



*4. Panicum capillare gailingeri Nash. 



Hamilton County, with the typical form. Probably of wider distribu- 

 tion in the State. 



5. Chactochlua verticillata (L. ) Scribn. (Ixophorus v. ) Fox-tail Grass. 



In waste places about dwellings, Tippecanoe County. Previously 

 reported only from Marion County. (State Catalogue, p. G30.) 



6. Aristida oligantha Michx. 



Common along the Mouon Railroad in Putnam County, growing in 

 sandy soil. "Found in the counties bordering on the Ohio and lower 

 Wabash rivers." (State Catalogue, p. 633.) Probably a railroad migrant, 

 but now well established. 



*7. Bromus purgans L. 



Putnam County, in thickets. In his elaboration of the Crarnineae for 

 Britton's Manual Nash has included this species with B. ciliatus, from 

 which it is easily distinguished by having the flowering glumes pubescent 

 throughout, remarking that "the form known as var. purgans * * * 

 may be distinct." Later he has separated the two species in Small's 

 Flora of the Southern States. Probably of general distribution in the 

 State. 



*8. Bruuius erectus Huds. Upright Brome-grass. 



Tippecanoe County. This is the determination by the Bureau of riant 

 Industry of a specimen sent by Mr. Fisher of the Experiment Station dur- 

 ing the present season. 



9. Bromus tectorum L. Downy Brome-grass. 



Putnam County, common along railroads and in waste places. Pre- 

 viously reported from Lake, Madison and Tippecanoe counties. (Proc. 

 End. Acad. Sci. 1900: 137; 1904: 301.) 



*10. Lolium temulenium L. Darnel. 



Tippecanoe County. Streets of Lafayette, apparently introduced with 

 grass seeds.
