 disposition or phy Ho taxis of buds ; 

 (3) budding', as in the multiplica- 

 tion of yeast (Huxley) ; nu'clear ■^ , 

 in Syiichptriujn when the karyosome 

 of the parent nucleus gives off a 

 small karyosome whioh passes 

 through the nuclear membrane and 

 becomes an independent nucleus, 

 repeated until a definite gi'oup of 

 nuclei is formed (Griggs) ; Gem- 

 mid'iom = Tetraspoke ; genimi- 

 ferous {/(^ro, I bear), bearing buds ;

 insertion of all equivalent lateral 

 members of ^n axis, in order of 

 age. 



Genetic'ian, an expert in Genet ics

 bent knees), abruptly bent so as to
