example, of the flora of lime stone clifTs, of clay soils, of sand hills, etc. The 

 work needed is not so much a collection of plants as a collection of /ac^s verified 

 by plants. 



In the following notes I have not in all cases referred to Mr. Bradner's list of 

 the plants of Steuben County, because I have had no opportunity to examine his 

 collections. The references, save as indicated in the notes, are to material in the 

 possession of the Snrvey. A large number of interesting forms of Cypemcen' and 

 Gramineip have been omitted, because our knowledge of the distribution of these 

 forms in the State is too scant to justify any conclusions concerning them. 



Cardamine pratensis L. This rare Northern plant, which was included in the 

 State catalogue, but of which no specimen had been preserved, is now definitely 

 reported with verifying specimens from two localities. Wet banks of Calumet 

 River, Miller's, Lake Co., June 6, 1893 (E. J. Hill); Section 5, York Tp., Noble 

 €o., May 28, 1894 (W. B. Van Gorder). Mr. Van Gorder sent me specimens of 

 this plant last June, at which time I determined it to be C. pratensis L., a deter- 

 mination which was later confirmed by a careful comparison with the material in 

 the Gray Herbarium at Harvard University. Under date of November 6, 1895, 

 Mr. Van Gorder writes as follows: 



' ^ Cardamine pratensis L. grows plentifully on a tract of wet land, three or four 

 acres, in section 5, York Tp., Noble Co. This tract is a part of the Elkhart 

 River flat. I had seen the plant for several years, and at a distance thought it 

 C. rhomboidea DC. This last spring it was dry enough, and passing the place I 

 determined to know for sure. It flowers from May 15 to June 10. The specimen 

 sent you was collected May 28." 



The manual range of the plant is, '"Wet places and bogs, Vt. to N. J., Wis., 

 and northward ; rare." 



The following local references which I was able to collate while at the Gray 

 Herbarium during the j^ast summer may serve to show the interest which attaches 

 to this plant as a member of the Indiana flora :
