Prenanthes rueemosa Michx. "Open, grassy land, East Chicago, Ind., Oct. 

 5, 1892." (E. J. Hill.) Noble County (W. B. Van Gorder). The range of this 

 species in Indiana seems to be limited to the northern tier of counties. The form 

 is found in "plains, N. Maine to N. J. and northward," though extending also 

 into Missouri. It is easily distinguished from the other species of the genus 

 found in the State by its heads being in crowded clusters, and could scarcely have 

 escaped the attention of collectors had it been of any general distribution. 



Pyrola chlorcmtha Swartz. "Sandy woods. Whiting, Ind., May 25, 1878." 

 (E. J. Hill.) A northern form, ranging from Labrador to Minnesota, northward 

 and westward, with the single record from Indiana as indicated. The specimens 

 in the possession of the Survey are, so far as known, the only ones from the In- 

 diana station in the herbaria of the State. 



Trientalin Americana Pursh. "Damp woods, Miller's, Ind., May 11, 1878."^ 

 (E. J. Hill.) "In tamarack marshes in moss near the roots of trees. Very com- 

 mon in some places. Noble County." (W. B. Van Gorder.) The mass distribu- 

 tion of this species is decidedly northern, its southern limit being the northern 

 tier of counties in Indiana, save where it extends southward along the mountains. 

 It will probably be found in all of the northern counties, but need scai-cely be ex- 

 pected farther south. 



Menyanthe!^ trifoliatd h. "Bogs and peat marshes, Pine Station, Ind. May 

 13, 1876." (E. J. Hill.) " Moist shores of lakes — very common at Pleasant Lake, 

 Noble Tp., Noble Co." (W. B. Van Gorder.) Whiie the sixth edition of Gray's 

 Manual includes Indiana in the range of this species, its authenticated distribu- 

 tion is confined to the stations mentioned. It probably occurs throughout the 

 northern portion of the State in favorable localities. 



Conrolndus arveni^i'i L. "By railroad. Pine Station, Ind. July 28, 1875. 

 Rare." (E. J. Hill.) Also reported from Jay, Delaware, Wayne and Randolph 

 Counties (Phinney), and Dearborn Co. (Collins). This adventive species, hereto- 

 fore restricted to North Atlantic States, has evidently made lodgment in Indiana. 

 I am inclined to think the Dearborn County reference somewhat doubtful, judg- 

 ing frgm the general range of the plant and taking into consideration the means 

 of distribution to which the presence of this intruder is evidently dne. I believe 

 its range in the State will be found limited to the northern and central counties. 



Siachys hyssupifolia Michx. "Wet, sandy banks, Laporte, Ind. July 22, 

 1875." (E. J. Hill.) Also collected at Laporte by C. R. Barnes. The State cata- 

 logue notes the plant as occurring from " Marion Co. and northward." The Ma- 

 rion County reference was doubtless based upon the authority of the late Dr. H. 

 E. Copeland, who was an exceedingly keen observer, but who, unfortunately, left
