69. Tragopogon porrifolius L. Oyster Plant. 



Putnam County, in waste places about Greencastle. Previously re- 

 ported from Wells County by Deani. (Proc. Ind. Acad. Sci. 1900: 142.) 



*70. Silphium terebinthinaceum pinnatifidum (Ell.) A. Gr. 



Hamilton County. The citation of the species (State Catalogue, p. 

 982), is incorrect, as the specimens have laciniate radical leaA r es. 



71. Helianthus petiolaris Nutt. 



Tippecanoe County, along- the Big Four Railroad west of Lafayette. 

 Previously reported from Lake County. (Proc. Ind. Acad. Sci. 1900: 141.) 



72. Synosma suaveolens (L. ) Raf. 



Hamilton County. The material first collected of this species was 

 defective, and so determined as Coleosant litis grandiflorus and reported 

 to Dr. Coulter. Later collections of material made a correct determina- 

 tion possible. The latter species should, therefore, be stricken out of the 

 doubtful list of Indiana plants. (State Catalogue, p. 008.) 



73. Centauria cyanas L. Blue Bottle. 



Tippecanoe County, in cultivated ground and about dumps. 



*74. Centauria solstitialis L. Yellow Star Thistle. 



Dearborn County. This plant was sent to the experiment station 

 under date of October 10, 1905, by Lute Helm of Moores Hill, who re- 

 ported it as a weed in alfalfa fields. It is an old world plant which is 

 sparingly naturalized in the Southern States. It can be readily distin- 

 guished from C. calcitrapa by its yellow flowers. This species is not in- 

 cluded in Brittoms Manual. 



Lafayette, Ind., November, 1905.
