Some Hybrids 25 
Blooming period: Late, practically simultaneous with that of 
Botuudifolia. 
Fertility of the flowers: Since the vine is staminate, we can test 
only the pollen grains for fertility. A microscopic examination reveals 
a mixture of mostly shriveled and angular grains, but also some that 
are perfectly normal in shape. Pollination tests indicate that some of 
the pollen grains are fertile. The pollen is mostly sterile because of 
hybridization. As this vine happens to be staminate, no description of 
fruits and seeds is possible. 
II- b. Heebemont X Botundifolia (G-52), 1916 and 1917. 
The only difference between these vines and the preceding one lies 
in the following characters : 
1. The color of the growing vines, leaves, tendrils, etc. is a deep 
reddish-brown. 
2. The leaves are variably lobed. 
3. These vines undoubtedly will bear two types of hermaphroditic 
flowers similar to those of the Wincliell-Rotundifolia hybrid lots of 
1916 because the male parent is one of the identical vines, G-52. The 
blooming period of these vines might be more intermediate between the 
two parent species. 
4. The perfect and the imperfect hermaphroditic vines of these two 
lots will probably hear fruit which will he described in a later pub¬ 
lication. 
5. These vines will also he more or less sterile because of hybridiza¬ 
tion. 
III- a. Malaga Seedling Ho. 1 X Botundifolia (G-52), 1916. 
General character of plants: Vines are somewhat variable. Some 
are indicative of tall climbers while others seem to he more of the 
spreading type. While the lobing of the leaves is somewhat variable, 
nevertheless, all possess typical hybrid characters. Hot much branched. 
Vigor of vine: Variable from very strong to very weak. 
Canes: Long, slender, fairly strong, somewhat zigzag, few in num¬ 
ber, strongly angled on tip of cane, more or less rounded on the base, 
compressed, obscurely striated. 
Wood: Softer than Botundifolia but harder than Vinifera; new 
w r ood greenish in color. 
Pith: Green, filled with starch during the dormant season, mostly 
continuous, occasionally interrupted by a diaphragm. In comparison 
with the diameter of the cane, the pith column is larger than in 
Botundifolia and smaller than in Vinifera. At the nodes the pith 
cells are more compressed than elsewhere.
