occurred in the proportions expected according to Mendel's laws, but in 

 others this was not so clearly shown. The Mendelian proportions were 

 perhaps best seen in the segregation of the character of fleshiness or 

 " bulbing " in the lower part of the stem shown in the second generation, 

 but were not visible only here, as in several instances the character of 

 the foliage also showed the same kind of phenomena. 



It is noticeable that the hispid green-leaved turnip crossed with the 

 hispid glaucous -leaved swede proved sterile, and that ragged Jack kale 

 and asparagus kale, which like the swede have hispid glaucous foliage 

 when young, cross readily with the swede. 



A few unaccountable and interesting phenomena were met with, such 

 as a form of leaf in the second generation totally unlike that exhibited 

 by either of the parents, and, in the case where the drumhead cabbage 

 was one of the parents, in the appearance in the second generation of a 

 purple coloration in the foliage.
