gatae; zygomorph’ic, zygomor’- 
phous (uop¢), shape), used of 
flowers which are divisible into 
equal halves in one plane only, 
usually the antero-posterior, ¢/. 
ACTINOMORPHIO; Sachs extends 
the meaning to such flowers as 
may be equally bisected in any 
one plane, as Dicentra; Zygo- 
morph’ism, or Zygomor’phy, the 
state just described; it may be 
diag’onal~, as in Solanaceae, or

in yeast; cf. ANTHOZYMASE, and 
ZYTHOZYMASE ; zy mic, relating to 
fermentation; Zy’mogen (yevvdw, 
I produce), the ‘‘ mother of fer- 
mentation,” an antecedent body of 
an enzyme ; zymogen’‘ic, applied to 
a peptonising enzyme ; Zymohydro-
