shows that his V. bicolor applies to some cultivated variety 
of Vitis vinifera with “berries round, soft, black and white on 
the same branch,” and further, the description is placed in 
Section II, “Exotic Grape Vines.” 
Section I of Rafinesque’s “monograph,” treats of the 
“North American Grape Vines,” and among the many species 
so inadequately defined, the real Vitis bicolor of LeConte, 
may exist under the names: V. callosa, V. hyemalis, V. labrus- 
coides or V. dimidata, but it is quite impossible to find any- 
thing in the description of these four, which might positively 
indentify them with Vitis bicolor LeConte, here renamed in 
his honor. 
In this connection it should be noted that while most of 
Rafinesque’s names in the genus Vitis are impossible of recog- 
nition, they nevertheless render several later names invalid,

The description by Rafinesque reads as follows: 
“Partly pubescent and clammy; leaves petiolate, elliptical, 
lanceolate, acuminate at both ends, mucronate, serrate, base 
entire, flowers corymbose, terminal and axillary, glomeru- 
lated ; folioles of the perianthe ovate-lanceolate, acute, rufous, 
ciliolate—A fine species not uncommon in Kentucky in fields 
and woods. It belongs to the genus Gynema of my Flora 
Ludoviciana. Stem two to three feet high. The whole plant 
has a very strong balsamic smell. It blossoms in August and
