a mistake in that the author confused the county with Jef- 

 ferson Co., Kentucky. Young does does not mention it in his 

 Botany of Jefferson County, Indiana, 1871.) 



In the Catalogue of the Phanerogamous and Vascular Crynto- 

 gamous Plants of Indiana, prepared by the editors of the Botani- 

 cal Gazette and C. R. Barnes in 1881, the only word indicating 

 the distribution is "Knobs." 



In Stanley Coulter's Catalogue of the Flowering Plants and 

 Ferns of Indiana (1900) we read: "It occurs in Jefferson and 

 Clark Counties sparingly. No other stations are reported." 

 (The records from Jefferson County, Indiana, are probably 

 erroneous; see above.) 



In Short's Fourth Supplementary Catalogue of the Plants of 

 Kentucky we read: '^^Psoralea congesta, — a new species lately 

 discovered by Dr. Clapp and Mr. Jones of New Albany, on 

 the islands of the Ohio River near that place." (This specific 

 name was never published but it appears on the type sheets of 

 P. stipulata.) 



I have written to Mr. C. C. Deam, Bluffton, Indiana, to 

 Prof. Stanley Coulter at Purdue University and Prof. Young at 

 Hanover College. Mr. Deam has never collected it. He an- 

 swered among other things, "The area about the Ohio Falls is 

 now all town and there is very little chance for anything to 

 survive there. If it is a plant of low ground and local it is 

 no doubt extinct now, as all area about the Falls is under culti- 

 vation or has buildings on it." I understand that the Rock 

 Island, the original locality, was blasted away some years ago 

 when the Ohio was made more navigable. 



Professor Coulter answered that in preparing his catalogue 

 he "relied for citations from Jefferson County on the cata- 

 logues" by A. H. Young, J. M. Coulter and C. R. Barnes (res- 

 pectively). Young's catalogue does not cite P. stipulata, J. 

 M. Coulter's I have not seen unless it is the one published by 

 the editors of the Botanical Gazette. In Barnes' catalogue the 

 plant is credited to Jefferson County, Indiana, but I believe 

 that this County has been confused with Jefferson County, 

 Kentucky, where the plant has existed. In a later letter, 

 Prof. S. Coulter added: "I do not believe the plant exists at 

 present in Indiana. I have no specimen of it in my herbarium. 

 I have written to my brother about it and his reference was from 

 Clapp's collection."
