The wood is intermediate in color and hardness and bench-grafts 
grow readily. 
The pith is more like that of Rotundifolia than that of Euvitis, but 
the occasional diaphragms and the indications of such structures at the 
nodes, also the occasional brown, dead pith cells without starch grains 
are characteristic of Euvitis. 
The bark on both the young and on the old wood is of an intermediate 
character although the persistence of this bark to the wood is more of 
a Rotundifolia character. In some hybrids (Vinifera-Rotundifolia 
1916) the bark is inclined to be somewhat shreddy hut not entirely like 
that of Euvitis. 
The nodes may be said to be intermediate in character. 
The leafbuds are probably slightly larger than in Rotundifolia but 
their shape, especially at maturity, more nearly approaches that of the 
Euvitis bud. 
The young growing shoots of the hybrid vines generally are soon 
clothed with foliage, but at times a shoot grows more rapidly and 
appears more or less naked. 
The leaves are hybrid in character. The size of the leaf is prac¬ 
tically that of Rotundifolia, while the lobing and general appearance 
and the size of the stipules when compared with the sizes of the leaves 
are characteristic of that of Euvitis. 
The tendrils are variable in size and forking. Some are small and 
weak while others are found to be large and strong. Some are simple, 
some bifid and all gradations between these two extremes, but none of 
the trifid type have been found. 
The flower-clusters are typically Rotundifolia in size but more like 
Euvitis in character. The type of flower in the Fi hybrid seems to be 
governed largely by the Rotundifolia species when it is used as the male 
parent, for example: 
Herbemont (perfect hermaphrodite) X Rotundifolia (staminate) 
produced 1 hybrid vine (staminate). 
Winchell (perfect hermaphrodite) X Rotundifolia (staminate) pro¬ 
duced 1 hybrid vine (imperfect hermaphrodite). 
Winchell (perfect hermaphrodite) X Rotundifolia (perfect her¬ 
maphrodite) produced hybrid vines 4 of which are perfect hermaphro¬ 
ditic and 1 imperfect hermaphroditic. 
Malaga Seedling No. 1 (imperfect hermaphrodite) X Rotundifolia 
(perfect hermaphrodite) produced hybrid vines 4 of which are perfect 
hermaphroditic and 2 imperfect hermaphroditic. 
The blooming period of the staminate and the imperfect hermaphro¬ 
ditic hybrid vines coincides more nearly with that of Rotundifolia than 
that of the Euvitis species, while that of the perfect hermaphroditic 
vines seems to be more intermediate, however, some overlapping occurs.
