Elower-clusters: Two types as regards size; tlie clusters on the per¬ 
fect hermaphroditic vines are small, practically the same size as those 
found on the Rotundifolia parent vine. The largest cluster produced 
about 300 flower buds. The clusters usually assume the characters of 
the Vinifera parent but the size and occasionally the branching of the 
Rotundifolia. The clusters on the imperfect hermaphroditic vines are 
much smaller and similar to those on the imperfect hermaphroditic 
Rotundifolia vines. 
Fig. 19. Two types of flower-clusters found among tlie Fi hybrid vines 
when Malaga Seedling No. 1 (imperfect hermaphroditic) is crossed with G-52 
(perfect hermaphroditic). The cluster on the left (perfect hermaphroditic) 
and the cluster on the right (imperfect hermaphroditic) are typical in size 
of similar flower-clusters found among vines of the Rotundifolia species, 
otherwise the clusters are hybrid in character. Reduced. 
Flowers: Perfect hermaphroditic and imperfect hermaphroditic; 
stamens upright and pistils medium large in the perfect hermaphroditic, 
stamens reflexed and pistils well developed in the imperfect hermaphro¬ 
ditic flowers. 
Blooming period: Practically half way between that of the two 
parent vines.
