Fertiliza’tion (p. 100), (1) fusion of 
two cells (gametes) to form a new 
individual cell (zygote); (2) the 
effect of pollen, deposited on stig- 
matic surface, resulting in con- 
version of flower into fruit, and of 
ovule into seed; doub’le ~ one 
generative nucleus from the pollen- 
tube fuses with nucleus of egg-cell 
(oosphere), the other with the 
definitive nucleus, itself formed by 
fusion of the polar nuclei. 
Fibonac’ci Se’ries, Braun’s series of

the Germ. ‘‘ Hochblatt” ; a bract. 
floc’culose, like wool (Leighton).

yevos, offspring), causing fluores- 
cence, as certain bacteria. 
foeni’nus (foenum, hay), ‘‘hay-grey” 
(Hayne), 
Fo’lial = FouioLe. 
Fo'liole, Yol’iola, add, (2) employed by 
Spruce for the postical leaves of 
Hepaticae, those on the ventral or 
rooting surface; fo’liose, applied 
to a Lichen with a leaf-like ex- 
pansion of the thallus. 
Fol'licle, (3) « little bladder on the 
leaves of some Moases, as Pottia 
cavifolia, 
Fore-leaf, a translation of the Germ. 
“Vorblatt” ; a bracteole or pro- 
phyllum.
