Negative correlations are indicated between leaf width and liguleless 
leaves in all three groups, and in the brachytic and dwarf groups a corre¬ 
lation with length of leaf is found. The correlation with leaf width is in

the nature of a disherence, since the parental combination was liguleless 
and wide-leafed. Disherences of this nature where deleterious vari¬ 
ations are combined with characters of diminished size indicate some
