3o8 Appendixes 



Brassica. Kajanus has Investigated the genetics of 

 seme species of this genus, particularly napus and rapa and 

 their hybrids. He confirms older observations as to the 

 production of lumpy outgrowths (resembling "finger and 

 toe") as the result of certain such crosses, and in this 

 respect he found remarkable differences between reciprocals. 

 Zts. f. ind. Abstam,, 191 2, vi. p. 217. 



Cotton. Leake found the sympodial habit partially 

 dominant over the monopodlal, with many forms of blending 

 between the two types. The inheritance of the leaf-shapes 

 was determined by a special method of measurement and 

 it was found that certain shapes were always heterozygous.

 made.
