PolyyoneUa ariiculata Meissn. "Sand hills, Millers, Ind , October 1, 1881. 

 Flowers white or rose-colored." (E. J. Hill.) This seems to be the only authen- 

 ticated station for this species. Mr. Van Gorder includes it in his list of plants 

 of Noble County, published in pamphlet form in 1884, but excludes it from list 

 published in 1887 in Eighteenth Report of the State Geologist. I infer from this 

 that its inclusion in the first list was an error. Baird and Taylor also include it 

 in their "Flora of Clark County," but as they made no collections the record is 

 necessarily a doubtful one, with the probability against the accuracy of the de- 

 termination. The assigned range is: " Dry, sandy soil ; on the coast from Maine 

 to New Jersey, and along the Great Lakes." It can be readily seen that its distri- 

 bution in Indiana is in all probability limited to the northwestern counties. 



Shepherd id Cnn«f?eH.x-(N Nutt. "Sand ridges, usually near sloughs. Pine 

 Station, Lake County, May 13 and 27, 1876." (E. J. Hill.) This attractive shrub 

 has perhaps its southern station in this record. Its reported range is from "Ver- 

 mont and New York to Miciiigan, Minnesota and north and westward." It is 

 Avorthy of notice, perhaps, that in Indiana it occurs "near sloughs," while in 

 other regions it is found chiefly on rocky or gravelly banks. 



Euphorbia pohjcionifdlw L. " Sandy shores of Lake Michigan, Lake County, 

 Indiana, September 4, 1893." (E. .J. Hill.) The range of this species is probably 

 limited to the shores of Lake Michigan, at least so far as Indiana is concerned. 

 While in general appearance it might be easily confused with other species, it 

 is characterized by having seeds larger than those of any other species in section 

 Anii^ophylluin. 



Mijrtca aspleni/olia Kndl. "Sand hills, .Miller's, Indiana. Flowers collected 

 April 29 and May 30, 1882; fruit, July 4." ( E. J. Hill.) This is the only lo- 

 cality for the State and it was upon this collection that the range of the sjiecies 

 was extended in the sixth edition of Gray's Manual to include Indiana. 



Betnla papi/rifera Marshall. "Sandy soil. Pine Station. Ind. Flowers col- 

 lected May 18, 187fi ; fruit, September 3, 1876. Trees ten to thirty feet high." 

 (E. J. Hill.) The material furnished the Survey was somewhat scant, but seemed 

 sufficient to verify the determination. The petioles were shorter, perhaps, 

 than in the normal form, but this seemed the only deviation from type in the 

 leaf characters. The reduction in size from a tree fifty to seventy-five feet high 

 in the normal range, to that indicated above, is the most marked feature in this 

 extension of range. The form also occurs in northern Illinois, but I have no data 

 at hand which indicate whether or not a similar reduction in size occurs. The 

 species, as is well known, is northern in its general range.
