 phous (/Aop07/, shape), used of 

 flowers which are divisible into 

 equal halves in one plane only, 

 usually the antero-posterior, cf. 

 ACTINOMORPHIC ; Sachs extends 

 the meaning to such flowers as 

 may be equally bisected in any 

 one plane, as Dicentra ; Zygo- 

 morpn'ism, or Zygomor'phy, the 

 state just described ; it may be 

 diag'onal~, as in Solanaceae, or 

 trans'verse as in Papaveraceae ;

 a division of Phycomycetes pos- 

 sessing zygospores (Tubeuf) ; Zy'- 

 gophytes (<pvTbv, a plane), applied 

 to Algae which conjugate ; adj. 



zygophyt'ic ; Zygo'sis, M'Nab's 

 term for the union of gametes to 

 form a zygote ; Zy'gosperm (aTr^a, 

 a seed), a proposed emendation of

 a sphere) GAMETE ; Zy'gospore 

 (ffiropd, a seed), a body produced 

 by the coalescence of two similar 



ametes ; Zygospor'ophore { + 

 POROPHORE), the suspensor in

 (eldos, like), the result of the 

 union of two gametoids, that is, 

 apocytial structures, as in Mucor 

 (Hartog).

 SPORE), a motile zygospore.
