of the eleven was a true hybrid. This hybrid plant is living and healthy 
at this date. This is the first true Botundifolia hybrid with the native 
Euvitis grape (although of hybrid origin) that is recorded. It will be 
found fully described in our succeeding bulletin entitled, “Some Fj 
Hybrids Between Yitis Botundifolia and Belated Species.” In the 
spring of 1916 the variety Winchell was again used as the female parent 
plant and two self-fertile seedlings (Botundifolia) were used as the male 
parent. 
The first cross, Winchell x 1-1 (light colored seedling of Scupper- 
nong x Hope), resulted in 378 seeds. Of these, 79 hybrid seedlings that 
were strong enough to set in the nursery were obtained. 
The second cross, Winchell x G-52 (dark colored seedling of Thomas x 
Hope), resulted in 34 seeds. Among the resultant seedlings from this 
lot, only one strong hybrid was obtained and transplanted to the 
nursery. 
Vitis Rotundifolia X ( Vinifera-Labrusca-7Estivalis Hybrid) Var. 
Winchell 
In order to test the possibility of a reciprocal cross (Y. rotundifolia x 
Winchell), two Botundifolia seedlings X-32, a seedling of Scuppernong 
crossed with Light Male Ho. 2, and a dark selfed seedling of Hope were 
used in 1916. The first, an imperfect hermaphroditic vine (X-32), had 
ten hags covering twenty flower clusters. The flowers on these clusters 
were hand pollinated every morning with fresh Winchell pollen. Xone 
of the flowers developed fruit. 
The dark seedling of Hope, a perfect flowering vine, had only one 
flower cluster prepared and it was crossed with Winchell pollen. Xo 
fruit set on this cluster. 
Thus far our effort to hybridize Yitis rotundifolia with Winchell 
pollen has met with only negative results. Dearing (5) reports the 
production of some hybrid vines from Yitis rotundifolia crossed with 
Winchell as the male parent. It is quite apparent that hybrids of this 
reciprocal cross are rather difficult to obtain. 
Vitis Bourquiniana Var. Herbemont X Vitis Rotundifolia 
In 1912 Yitis bourquiniana var. Herbemont was used as the female 
parent and crossed with Y. rotundifolia, Light Male vine Xo. 2. In the 
fall of the year 28 seeds were harvested. Of these 28 seeds only two 
germinated and these died soon afterward. 
In 1913 Herbemont was crossed with Y. rotundifolia, Light Male vine 
Xo. 1, as the pollen parent. Eour clusters of the Herbemont vine were 
emasculated and later crossed with pollen from the male vine. In the 
fall 19 seeds were gathered from this cross and out of this lot of seeds 
in 1914 one true hybrid vine, strong enough to withstand the vicissitudes
