Collected by Mr. Wm. Jones of Portland, Ky. 

 [Dr. Clapp — rec'd. July 9th, 1839] 



There is also another specimen in said herbarium from "Rock 

 Island, Falls of Ohio, June, 1842, C. W. Short, M.D.," and in 

 the Columbia University Herbarium one labeled, "New Albany, 

 Ind." collected by A. Clapp. This was received from Matin- 

 dale. New Albany was Dr. Clapp's home. As no date is 

 given, this might have been a specimen from the original col- 

 lection or it might be an additional station. In the herbarium 

 of The New York Botanical Garden there is one from the Falls 

 of Ohio collected by Short in i860. The Gray Herbarium and 

 the U. S. National Herbarium contain no other specimens ex- 

 cept duplicates of one or two specimens given above, and no 

 specimens have been collected since i860. The plant seems, 

 therefore, to have been confined to Clark County, Indiana, and 

 JeflFerson County, Kentucky. 



The species is not mentioned in the earlier editions of Wood's 

 Classbook, but in the editions of 1 863-1 872 (p. 315), and' in his 

 Botanist and Florist (i 873-1 889, p. 92), there are short descrip- 

 tions and the locality is given as Ohio Falls, Ky. In Gray's 

 Manual (ed. i, p. 105) the distribution is also given as Ohio 

 Falls. This remains unchanged up to the 6th edition, where 

 it is changed to "Rocks, S. Ind. and Ky, " In the New Gray's 

 Manual it reads: "Limestone ledges, Ohio River above Louis- 

 ville, Ky., and New Albany, Ind." 



In Britton & Brown's illustrated Flora (both editions) and 

 in Britton's Manual (both editions) the distribution is given 

 as, "in rocky places, Ohio, Indiana and Kentucky." The 

 extended distribution seems to be due to Miss A. M. Vail's 

 revision of the genus (Bull. Torrey Club 21: 113), where she 

 erroneously placed "Falls of the Ohio" and "Rock Island" in the 

 State of Ohio. Miss Vail also states that in Short's herbarium 

 at the Philadelphia Academy there is a note "That he never 

 found this plant in fruit growing wild, and that he cultivated 

 it vainly for years. " 



In local publications of Indiana and Kentucky we find the 

 following records: 



In Barnes' Catalogue of the plants of Jefferson County (1881, 

 p. 7) is given "Knobs" without authority. (This is probably
