NORTHERN LIMIT OF WILD GRAPE YINES—LAWSON. 103 
V. Lasrusca, Linn. Canada.—Pursh, Torrey & Gray. 
Near the Falls of Niagara—Provancher. Extends south to 
Georgia and west to Arkansas and Texas. 
Torrey speaks of the fruit of the wild plant as having a strong 
disagreeable flavour, whilst when cultivated “it is as pleasant as. 
any of the varieties of Vitis vinifera.” In Hooker's Flora (pub- 
lished so long ago as 1833) it is remarked that “two sorts are 
much esteemed at New York, and known under the name of 
‘Bland’s-grape’ and the ‘Isabella-grape.’ ” 

V. CORDIFOLIA, (V. vulpina, of Hook.) Shores of Lake Ontario. 
west from Kingston; several places on the banks of the St. 
Lawrence, as at Thousand Islands, Brockville, La Chine, ete. 
Extends south through the United States to Florida and west 
to Arkansas. 
V. riparia, Mich. Canada—Mr. Cleghorn, Mrs. Percival. Lake- 
Huron.—Dr. Todd, extending to the south end of Lake Winnipeg 
in lat 50 degrees N., (Hook. FI. B. A.) 
Nicolet, P. Q., and Malden Ont.—Dr. P. W. Maclagan. 
Belleville, common, especially along streams.—J. Macoun. Lisle- 
aux-Coudres.—Provancher. Some of the localities may belong to 
V. cordifolia. Extends through the Uuited States south to 
Virginia and west to Arkansas. 
Without specimens from the several localities, or careful deter- 
minations made on the spot by competent botanists, it is impos~ 
sible to assign with certainty to their proper species the stations 
quoted for V. cordifolia and V. riparia. Dr. Englemann made 
a very careful examination of the distinctive characters of the 
N. American species of Vitis, and characterized V. riparia, as 
differing from its ally as follows: — “Leaves larger, usually 
incisely three lobed, the lobes long-pointed; panicles small, 
rather simple; berries larger and mostly with bloom; seeds 
larger, obtuse and somewhat obcordate and with an inconspicu- 
ous raphe. May, earlier than the allied species."—See Gray’s 
Manual, fifth edition, eighth issue,—Addenda, p. 679 (January , 
1868). V. cordifolia “has the berries black without bloom, the
