Plants of Indiana (1881), by the editors of the Botanical Gazette 



By E. J. Hill. 



Having found this grape the past summer growing wild in the 

 woods of the dune region of Lake and Porter Counties, Ind., the 

 question arose as to its range, since published statements are some- 

 what contradictory. In the last issue of the " Synoptical Flora of 

 North America" (1897),* Professor Bailey says : " Not known to 

 occur west of eastern New York in the north, but reported from 

 southern Indiana, Munsott" He remarks on the ease with which 

 it may be confounded with V. aestivalis. In the Catalogue of the

Jefferson County, which is in the southeastern 



part of the state bordering on the Ohio River. In the " Catalogue 

 of the Flora of Minnesota" (1884) by Warren Upham, it is said to 

 occur " frequently according to Clark, in the eastern part of the state 

 as far northward as Pine County (Upper St. Croix), and rarely 

 on the St. Louis River (Head of Lake Superior), Lake Pepin 

 Miss Manning." Britton and Brown, in their " Illustrated Flora" 

 ( l8 97). give its range from New England to Minnesota, Georgia 

 and Tennessee. Dr. Engelmann in The True Grapes of th« 

 United States, i883,t says of it : "This species usually known 

 as the Fox-Grape, or Northern Fox-Grape, is a native of tin 

 Alleghany Mountains and of their eastern slope to the southeast 

 from New England to South Carolina, where it prefers wet thicket 

 or granitic soil. Here and there it descends along streams to th< 

 western slope of the mountains, but it is a stranger to the Missis- 

 sippi Valley proper." " Large and downy-leaved varieties of V. 

 aestivalis are in the west and southwest not rarely mistaken 

 for Labmsca r Accordingly in some of his papers on Vitis 

 he corrects such determinations as came to his notice. 



In another paper the following statement is made: " V. La ' 

 brusca is our most local species, being confined to the Alleghany 

 Mountains and the region between them and the Atlantic, unknown 

 in the Mississippi Valley or beyond. Whatever has been called 

 so there, or in Louisiana or Texas, is a laree and downy-leaved 

 form of aestivalis, always readily distinguished by its ' intermit- 

 tent' tendrils, while Labmsca has more or less ' continuous' ten
