species: V. vinifera, Y. labrusca, Y. bourquiniana, Y. cordifolia and 
the hybrid variety Winchell. 
2. The Muscadine group when hybridized with species of Euvitis is 
not as prepotent in regard to its external or visible characteristics as 
has generally been supposed. 
3. The hybrids which are derived from Yitis rotundifolia and species 
of Euvitis are almost sterile and this sterility is due mainly to hybridi¬ 
zation. The perfect hermaphroditic forms are sterile from this cause 
alone, while the imperfect hermaphroditic and the staminate vines are 
sterile because of the double phenomenon of sex or intersexualism and 
hybridization. 
4. The so-called “false hybrids” which have been reported at various 
times in horticultural literature and which are said to be hybrids 
between Muscadine vines and species of Euvitis are not hybrids but 
straight seedlings of the supposedly dominant parent species, Yitis 
rotundifolia and Yitis munsoniana.
