on our dry ridges, which produce larger grapes wi 
juicy and palatable pulp, undoubtedly belong to V. estivalis. 
Vitis estivalis of Prof. Swallow, “the largest of all our 
vines,” “with stems like huge cables,” can not be any thing 
but the same Vitis cordifolia ; while the variety “of the 
limestone ridges,” etc., probably has to be referred to the true 
V. estivalis. 
3. Vitis cordifolia is erroneously considered a smaller 
plant than those enumerated under 2 and 3. The true V. 
cordifolia and its variety, 4. V. riparia, which forms com- 
plete transitions into the former, are by far the largest Amer- 
ican grape-vines. 
5. Vitis vulpina, Lin., differs essentially from all the other 
k, which i 
large size in our alluvial bottoms. The vines of smaller size 
h more 
joining Indian country is common on the gravelly banks of 
the smaller streams, which are overflowed during freshets. 
My specimens of this plant are not complete enough to class 
it with acing confidence, but they indicate a close alliance 
and probably identity with Vitis rupestris, Scheele, of West- 
ern Texas, characterized by a low, bushy, rarely climbing 
stem; small, roundish, glabrous leaves, coarsely dentate, al- 
most truncate, or with a broad sinus at base; by middle sized 
berries, in small bunches, of pleasant taste. It has much the 
growth and appearance of the Muscadine, but can always be 
distinguished by the shaly bark of the stem and the lighter 
ore S. : 
The wild muscadine grape as well as its cultivated variety, 
the Scuppernong, has been grown in gardens about St. Louis, 
but has never, I believe, borne fruit, showing that our climate 
does not suit it. a ee 
No. 6, Vitis bipinnata, Torrey & Gray, and 7, Vitis ind 
visa, Willd., can not come into consideration in a revieW ' 
our native grape-vines, which considers only their economica 
value, as they do not bear edible fruit. They belong to the 
section Cissus (genus Cissus, Lin.) together with Vitis _in- 
cisa, Nutt., which is found from Florida to Texas. — wits 
indivisa is common throughout the State, especially in 9 
valleys of our larger rivers. Vitis bipinnata is a southemm 
species and was not observed by me north of Arkansas, 
though it may occur in the southern parts of the State.
