Leontodon autumnale L. Fall Dandelion. Lion's Tooth. 



Wells County (C. C. Deam). In yards at Bluffton, introduced in grass. 

 Helianthits pedolaris Nutt. Prairie Sunflower, 



Lake County (E. J. Hill). A western prairie form occasionally found in 

 dry, waste places eastward. Probably introduced into Indiana along east 

 and west railway lines leading into Chicago. 

 Seneeio Balsamitce Muhl. (S. aureus Balsamit?e T. and G. ) 



Wabash County (J. N. Jenkins). The range of variation in S. aureus, so 

 widely distributed throughout the State, is the only ground for question- 

 ing the above citation. The material submitted seems to bear out the 

 description of the species Balsamitw. It is therefore included in the list. 

 Centaurea Jacea L. Brown or Rayed Knapweed. 



Lake County (E. J. Hill.) A form fugitive from Europe, usually found in 

 waste places north, or in ballast about seaports. 

 Wolffiella Floridana (J. D. Smith). Thompson. 



Marshall County, near Culvers (H. Walter Clarke). The abundant material 

 furnished by Mr. Clarke leaves no room for questioning the accuracy of 

 the reference. The range of the species by this citation is sharply ex- 

 tended northward, its assigned limits heretofore being "Georgia and 

 Florida to Missouri, Arkansas and Texas.'" 

 Wolffia papulifera Thompson. Pointed Duckweed. 



Gibson County (J. Schneck, M. D. ). "Two miles east of Mt. Carmel, 111., 

 in Indiana. This is another decided extension of range, in this case 

 eastward, the recorded range of the species being, " Kennett and 

 Columbia, Mo." (Britton and Brown, Vol. 3, p. 510.) 



SPECIES ESCAPED FROM CULTIVATION. 



Pinus resinosa Ait. Canadian Pine. Red Pine. 



Wabash County (J. N. Jenkins). A northern form which will probably not 

 maintain itself in our area. 

 Populus balsamifera candicans (Ait.) A. Gray. Balm of Gilead. 



Gibson County (J. Schneck, M. D.). Specimens of this form were in the 

 Purdue herbarium at the time of collating the catalogue, but it was not 

 included, being considered as an escape, and there being no record of its 

 persistence. 

 Broussonetia papyrifera (L. ) Vent. Paper Mulberry. 



Gibson County (J. Schneck, M. D. ). An evident escape from cultivation. 

 The inclusion of the species should depend upon the persistence of the 

 form in the wild state.
