1072 Excluded Species 



plants of the same county subsequent to that of Coulter. He was in close 

 communication with the preceding authors, but he does not list this species. 

 It thus appears that Coulter and Barnes did not agree with Young in his 

 determination of this form of Ilex. Also reported by Scott from a tamarack 

 bog near Leesburg in Kosciusko County. This is an Appalachian Mountain 

 species and since Scott did not report Ilex verticilkitci which I have collected 

 in this bog, it is fairly safe to presume that this report should be trans- 

 ferred to Ilex verticillata. 



Mountain woods from N. Y. and Pa. to Ga. and Ala. 



430. Ilex opaca Ait. Reported in Coulter's Catalogue for the Lower 

 Wabash Valley on the authority of Robert Ridgway. Ridgway told me 

 that he had never seen it in Indiana as a wild plant, so there must have 

 been some confusion in the records. 



Atlantic coast from Mass. to Fla. and the Mississippi Valley from 111. 

 to the Gulf and west to Tex. 



431. Acer pennsylvanicum L. This tree was reported from the en- 

 virons of New Harmony by Prince Maximilian under the name of Acer 

 striatum. Since there is no preserved specimen, it is excluded. Robert 

 Ridgway told me that it occurred just across the Wabash River in Illinois. 



N. S. to Lake Superior, southw. in the Great Lakes region and in the 

 mts. to Ga. 



432. Cardiospermum Halicacabum L. Balloonvine. Reported from 

 Clark County (Baird & Taylor) ; Jefferson County (Barnes, J. M. Coulter, 

 and Young) ; and from the Lower Wabash Valley (Schneck). I have it 

 from Wells County. This is an occasional garden escape and probably not 

 yet established. All reports and specimens date back more than 30 years. 



Introd. from the Tropics and escaped from gardens. 



433. Rhamnus cathartica L. Common Buckthorn. Reported from 

 Wayne County by Phinney and from Monroe County by Andrews. Neither 

 author makes any comment so we are at a loss to know whether it is an 

 escape and, if so, how successfully it has maintained itself. A. R. Bechtel 

 found it as an escape in Montgomery County. We planted it in our abore- 

 tum and before we observed it hundreds of seedlings came up. We at once 

 destroyed these and the parent pistillate trees. 



Introd. from Europe and will escape in Indiana if cultivated. 



434. Vitis rotundifolia. Michx. Muscadine Grape. A specimen of 

 Cissus Ampelopsis was referred to this species by Deam in Proc. Indiana 

 Acad. Sci. 1911: 372. 1912. This was an error and was corrected in Proc. 

 Indiana Acad. Sci. 1912: 83. 1913. 



435. Vitis rupestris Scheele. Sand Grape. A form of Vitis vulpina 

 found in the dunes bordering Lake Michigan was referred to this species 

 in Coulter's Catalogue upon the authority of L. H. Bailey. This was a 

 wrong determination of Vitis riparia var. syrticola (Fern. & Wieg.) Fern. 



S. Pa. to Mo. and southw.
