___§ 68 Rege! on the Species of Vitis—E. Regel, in Garten Flora ; 
efor J uly 28, 1878, publishes a revision of the species of Vitis from 
North America, Northern China and Japan. Our grapes have 
_ always been a puzzle to botanists, and it may interest the readers 
_ of Tax Burierin to see what disposition has been made of our 
Species by one who studies them in comparison with those from 
countries nearly related botanically. ; 
Taking the species as they are enumerated in Torr. & Gray’s FL 
N. Amer., I give in brief Regel’s views of them. 
V. bipinnata, Torr. & Gray’s Fl., I., p. 243, he hasas V. arborea, 
Inn, ae : 
V. incisa, Nutt., in Torr. & Gray, is left undisturbed. ; 
V. indivisa, Willd., is placed as V. heterophylla, var. a, cordata. 
VY. Labrusca, in its many forms, is disposed of in three varieties : 
&, typica, f, estvalis and y, lanata, the first two of which have 
several sub-varieties. In his arrangement V. candicans, Englmn., 
in Smithson. Contrib. IIL, 5, p. 32, and V. mustangensis, Buckl., 
in Proc. Phil. Acad., 1861, p. 451, would both be V. Labrusca a, 
_ lypica,c, ficifolia, and our V. estivalis Michx.; Torr. & Gray, is 
V. Labrusca, 8, westivalis. 
V. zestivalis, Michx; Torr. & Gray: See V. Labrusca. 
V. cordifolia, Michx; Torr. & Gray: See V. vulpina. _ 
V. riparia, Michx.; Torr. & Gray, was by Dr. Gray in his Manual 
reduced to a variety of V. cordifolia, and Regel has it as V. 
vulpina, &, riparia.’ a 
_V. vulpina, Linn.; Torr. & Gray, Regel makes four varities, 
his var. a, rotundifolia includes our V. vulpina, and our V. cordi- 
_ folia is his var. f. : : no 
The following is Regel’s conspectus of our species, which will . 
_ Serve to show, in brief, the characters upon which his classification 
Is based: : ee 
_ A. Inflorescence cymose, Petals spreading in flower, soon decidu- 
ous, . 
| a. Cymes from opposite the leaves from the shoots of the 
current year. 
_ _ * Leaves pinnate or pinnately compound. 
1. Vitis arborea, L. , : 
** Lower leaves three-lobed, upper three-foliolate, 
 %. Vitis incisa, Nutt. 
** Leaves entire or palmately lobed. 
8. Vitis heterophylla, Thunb. | 
-__-b, Cymes from the branches of previous years.
